Answer:
2x = 6
Step-by-step explanation:
Simplify the following algebraic expressions.
- 6x + 5 + 12x -6
2(x - 9) + 6(-x + 2) + 4x
3x2 + 12 + 9x - 20 + 6x2 - x
(x + 2)(x + 4) + (x + 5)(-x - 1)
1.2(x - 9) - 2.3(x + 4)
(x2y)(xy2)
(-x2y2)(xy2)
Solution
Group like terms and simplify.
- 6x + 5 + 12x -6 = (- 6x + 12x) + (5 - 6)
= 6x - 1
Expand brackets.
2(x - 9) + 6(-x + 2) + 4x = 2x - 18 - 6x + 12 + 4x
Group like terms and simplify.
= (2x - 6x + 4x) + (- 18 + 12) = - 6
Group like terms and simplify.
3x2 + 12 + 9x - 20 + 6x2 - x
= (3x2 + 6x2) + (9x - x) + (12 - 20)
= 9x2 + 8x - 8
Expand brackets.
(x + 2)(x + 4) + (x + 5)(- x - 1)
= x2 + 4x + 2x + 8 - x2 - x - 5x - 5
Group like terms.
= (x2 - x2) + (4x + 2x - x - 5x) + (8 - 5)
= 3
Expand and group.
1.2(x - 9) - 2.3(x + 4)
= 1.2x - 10.8 - 2.3x - 9.2
= -1.1x - 20
Rewrite as follows.
(x2y)(xy2) = (x2 x)(y y2)
Use rules of exponential.
= x3 y3
Rewrite expression as follows.
(-x2y2)(xy2) = -(x2 x)( y2 y2)
Use rules of exponential.
= - x3 y4
Simplify the expressions.
(a b2)(a3 b) / (a2 b3)
(21 x5) / (3 x4)
(6 x4)(4 y2) / [ (3 x2)(16 y) ]
(4x - 12) / 4
(-5x - 10) / (x + 2)
(x2 - 4x - 12) / (x2 - 2 x - 24)
Solution
Use rules of exponential to simplify the numerator first.
(a b2)(a3 b) / (a2 b3) = (a4 b3) / (a2 b3)
Rewrite as follows.
(a4 / a2) (b3 / b3)
Use rule of quotient of exponentials to simplify.
= a2
Rewrite as follows.
(21 x5) / (3 x4) = (21 / 3)(x5 / x4)
Simplify.
= 7 x
(6 x4)(4 y2) / [ (3 x2)(16 y) ]
Multiply terms in numerator and denominator and simplify.
(6 x4)(4 y2) / [ (3 x2)(16 y) ] = (24 x4 y2) / (48 x2 y)
Rewrite as follows.
= (24 / 48)(x4 / x2)(y2 / y)
Simplify.
= (1 / 2) x2 y
Factor 4 out in the numerator.
(4x - 12) / 4 = 4(x - 3) / 4
Simplify.
= x - 3
Factor -5 out in the numerator.
(-5x - 10) / (x + 2) = - 5 (x + 2) / (x + 2)
Simplify.
= - 5
Factor numerator and denominator as follows.
(x2 - 4x - 12) / (x2 - 2x - 24) = [(x - 6)(x + 2)] / [(x - 6)(x + 4)]
Simplify.
= (x + 2) / (x + 4) , for all x not equal to 6
Solve for x the following linear equations.
2x = 6

Why do many animals in grasslands stay together in herds?
a
Staying together allows them to eat the same food.
b
Staying together allows them to stay warm.
c
Staying together allows them to be safer from predators.
d
Staying together allows them to take care of the ecosystem.
Question 2 (3 points)
Fill in the blank of the following sentence to make it true:
An adaptation of plants growing in the _______________ biome is they have deep roots to help them get moisture when it's dry, as drought is common in this biome. Fires are also common here, so the plants' deep roots also allow them to regrow if there is a fire.
a
Tropical Rainforest
b
Tundra
c
Desert
d
Grassland
Question 3 (3 points)
Desert biomes are arid, or dry, environments that receive less than 10 inches of rain each year. Some deserts can be very hot, while other types of deserts can also be cold, like the Gobi Desert. A scorching hot desert like the Namib Desert in Africa cools rapidly each night when the sun goes down.
Which of the following is a behavioral adaptation that many animals living in a hot desert have developed to help them survive in a desert biome climate?
a
nocturnal, active only at night
b
migrating south during the winter season
c
hibernation
d
thick fur coats
Question 4 (6 points)
Select ALL of the following physical adaptations that plants found in a desert biome have developed to survive in this type of biome?
(Think about what we've learned about the characteristics of a desert biome climate)
a
large, broad leaves where water is evaporated quickly into the air
b
thick, waxy skin to hold in water
c
no leaves or have spines to prevent water loss
d
a shallow root system to soak up water quickly before it's evaporated
Question 5 (3 points)
Which of the following adaptations would best help a plant living in the understory or forest floor of a Tropical Rainforest biome?
a
Thin stems that bend but do not break in windy conditions
b
Small leave to reduce the amount of water loss
c
Large, broad leaves to consume as much sunlight as possible
Question 6 (3 points)
Poison dart frogs found in a Tropical Rainforest biome are brightly colored to aid in their survival in this type of biome.
Why is being brightly colored a beneficial adaptation for poison dart frogs?
a
to visually warn predators they are poisonous
b
to blend in with colorful flowers
c
to attract a mate
Question 7 (3 points)
How do extra layers of fat help animals survive in the Tundra biome?
a
It helps them sink deeper when dividing in the water to find food
b
It insulates their body to keep them warm
c
It provides them water
Question 8 (3 points)
Permafrost, the permanently frozen layer of subsoil of a Tundra, prevents plants found in this biome from pentrating this solid layer in order to grow deep roots.
What is a special adaptation that Tundra biome plants have developed to overcome this in order to survive there?
a
growing in clusters since clumping helps protect them the cold and wind
b
growing very tall to help reach more sunlight
c
large, broad leaves to help them get rid of excess water

Coupon A: 30% off of $63 shoes.
Coupon B: $22 rebate on $63 shoes.
Answer: Cupon B ($22 rebate on $63 shoes)
Step-by-step explanation: Cupon A would equal $44.10 while Cupon B would equal $41
The question you posted seems incomplete. You posted the set up information, but the actual question itself is missing. I'm assuming you want to find which is the better deal? If my assumption is correct, then go ahead and read on. If my assumption is incorrect, then you can ignore this post.
---------------
Solution:
The percent 30% converts to 0.30 when we move the decimal point two spots to the left. Note how 30% = 30/100 = 0.30
So saying 30% of 63 means 0.30*63 = 18.90, which is the amount of money we save. This value is smaller than the $22 rebate amount so that means Coupon B is the better deal.
We can see that if we go with Coupon A, then the final price will be 63-18.90 = 44.10; if we go for Coupon B, then the final sale price is 63-22 = 41. This is further confirmation that choice B is better.
Be careful though: The $22 rebate means that you'll have to mail (or possibly email) some kind of proof of purchase form/card. A bit of time will pass by until you can get the $22 in the mail. Some companies probably offer some kind of direct deposit. A rebate is basically a partial refund that acts more or less like a discount, but it's not an immediate discount. In short, you will not save the $22 right away and instead you'll be expected to pay the full $63 for the shoes when you're at the checkout counter. So if you want to save money right away, then go for option A. However, I still think option B is the better choice in the long run. Of course, it will depend on how long you're willing to wait for that savings.
