Factor the expression below.
x² - 64
A. (x+3)(x-8)
B. (x-8)(x-8)
C. (x - 16)(x - 4)
D. (x+16)(x-2)

Answers

Answer 1

Answer:

(x + 8) (x - 8)

Step-by-step explanation:

To factorise the expression follow the steps:

Think the factorising means you want like:-

  ( x + _ ) ( x + _ )

Now, add the numbers to get 0 & multiple together to get -64

 -64 = 8 x -8

 8 + -8 = 0

Now fill the numbers in the factorising mean which will give you,

( x + _ ) ( x + _ ) --> ( x + 8 ) ( x - 8 )

Therefore, the answer will be: ( x + 8 ) ( x - 8 )

I hope this will help you :)

Jerome photographed an aquarium that measured 12 inches by 18 inches by 24 inches. Lim photographed an aquarium that was 12 inches by 30 inches by 12 inches. Both aquariums are rectangular prisms. How much more volume does Jerome’s aquarium have than Lim’s?

Answers

Answer:

the answer is 864 in3

Step-by-step explanation:

Jerome photographed an aquarium that measured 12 inches by 18 inches by 24 inches.

So V=LxWxH....

12 x 18 x 24= 5,184

Then...

Lim photographed an aquarium that was 12 inches by 30 inches by 12 inches.

So= V=LxWxH

12 x 30 x 12=4,320

And they need to see who has more so 5,184-4,320=864in3

Which expression is equivalent to a2 + 2a – 8?
A. (a + 2)(a – 4)
O B. (a + 1)(a – 8)
o C. (a - 1)(a + 8)
D. (a + 4)(a - 2)

Answers

Answer:

D

Step-by-step explanation:

(a+4)(a-2)=a^2+2a-8

a*a=a^2

a*(-2)=-2a

a*4=4a

4*(-2)=-8

a^2-2a+4a-8=a^2+2a-8

what equation will give the perimeter of the figure? HELP HELP HELP

Answers

Answer:

(2l + 2w) + (a + b + c)

Step-by-step explanation:

The formula for the perimeter of a rectangle is

P = 2l + 2w

so if you substitute, it becomes

P = 2(12) + 2(2)

= 24 + 4

= 28

For the perimeter of a triangle the correct formula would be

P = a + b + c

The missing side in the triangle is 3 because 15 - 12 is 3.

If you substitute, it becomes

P = 2 + 3 + 6

P = 11

If we add both perimeters together we get the full perimeter of the figure which is

28 + 11 = 39

I am not sure if you wanted the answer as well but just in case :)

(c) Charmaine compared the statistics from her team's baseball season. She determined that having fewer hits did not imply that a player

There is no correlation between number of hits and number of balls caught.
There is a correlation between number of hits and number of balls caught. There may or may not be causation. Further studies would have to be

SUPER CONFUSED! EXPLAIN PLS! EMERGANCY!

Answers

Answer:

73.12m²

Step-by-step explanation:

Okay, you can break this figure into a half-circle and a triangle, we're going to start with the triangle (using the handy formula sheet you have up there)

12 x 8 = 96

96 x ½ = 48

Now we do the semicircle (the formula for a circle is pi x radius² )

the radius is half of the diameter so:

8 ÷ 2 = 4

4² = 16

we're using 3.14 for pi so:

3.14 x 16 = 50.24

Now we'd normally stop there, but this is only a semicircle, so we have to chop it in half again:

50.24 ÷ 2 = 25.12

Now we add both of those together:

48 + 25.12 = 73.12‬

So the area of the figure is 73.12m²

2. [tex]p \geq 8[/tex] where [tex]p[/tex] represents the total number of people.

4. [tex]p > 20[/tex] where [tex]p[/tex] represents the total number of people.

Step-by-step explanation:

Question 1 explanation: Since no more than 10 people are allowed in the elevator, that means 10 and under are allowed, so the inequality would be [tex]p \leq 10[/tex].

Question 2 explanation: Since the tour bus needs at least 8 people to sign up to run, that means 8 and more people will allow the tour bus to run, so the inequality would be [tex]p \geq 8[/tex]

Question 3 explanation: Since the most you will pay for a pair of jeans is $60, that means jeans costing $60 and under are fine, so the inequality would be [tex]c \leq 60[/tex].

Question 4 explanation: Since over 20 people showed up to the party, that means there were more than 20 people at the party, so the inequality would be [tex]p > 20[/tex].
