Compute $\sqrt{64} + \sqrt{225} - \sqrt{64 + 225}$.
Answer:
6
Step-by-step explanation:
Simplify the following:
sqrt(64) + sqrt(225) - sqrt(64 + 225)
Hint: | Evaluate 64 + 225.
64 + 225 = 289:
sqrt(64) + sqrt(225) - sqrt(289)
Hint: | Simplify radicals.
sqrt(289) = sqrt(17^2) = 17:
sqrt(64) + sqrt(225) - 17
Hint: | Simplify radicals.
sqrt(64) = sqrt(2^6) = 2^3:
2^3 + sqrt(225) - 17
Hint: | In order to evaluate 2^3 express 2^3 as 2×2^2.
2^3 = 2×2^2:
2×2^2 + sqrt(225) - 17
Hint: | Evaluate 2^2.
2^2 = 4:
2×4 + sqrt(225) - 17
Hint: | Multiply 2 and 4 together.
2×4 = 8:
8 + sqrt(225) - 17
Hint: | Simplify radicals.
sqrt(225) = sqrt(15^2) = 15:
8 + 15 - 17
Hint: | Evaluate 8 + 15 - 17.
8 + 15 - 17 = 6:

What is the complete factorization of x^2 + 2x − 63?
A. (x + 21)(x − 3)
B. (x − 9)(x + 7)
C. (x + 9)(x − 7)
D. (x − 21)(x + 3)
Answer:
C. (x+9)(x-7)
Step-by-step explanation:
(x*x)=x^2
(9*x)=9x
(-7*x)= -7x
(9*-7)= -63
x^2+9x-7x-63 = x^2+2x-63

A gardener will use up to 240 square feet for planting flowers and vegetables. She wants the area used for vegetables to be at least four times the area used for flowers. Let x denote the area (in square feet) used for flowers. Let y denote the area (in square feet) used for vegetables. Shade the region corresponding to all values of x and y that satisfy these requirements.

Answer:
9 is the correct answer all the best
Step-by-step explanation:
(x + 0.5)/6 = 19/12
2(x + 0.5) = 19 (multiply 12 on both sides)
x + 0.5 = 9.5 (divide 2 on both sides)
x = 9 (subtract 0.5 on both sides)
The answer is 9.

Two snakes race the speed of the first is 24 1/2 inches per minute and the speed of the other is 26 inches per minute how far apart with they be in 3 min? 10 min?
Answer:
637, 245
Step-by-step explanation:
Speed is the rate of change in the position of an object. The distance between the two snakes after 10 mins is 15 inches.
What is the relation between speed, distance, and Time?We know that sped, distance, and time all are in a relationship to each other. this relationship can be given as,
[tex]\rm{Speed = \dfrac{Distance}{Time}[/tex]
Given to us
Two snakes race The speed of the first is 24 1/2 inches per minute The speed of the other is 26 inches per minute What is the distance between them after 3 mins?The relative speed between them, as they are moving in the same direction, therefore,
Relative speed = (26-24.5) = 1.5 inches per minute
[tex]\text{Distance between them after 3 mins}= \rm speed \times \rm time[/tex]
[tex]= 1.5 \times 3\ mins\\= 4.5\ inches[/tex]
Thus, the distance between the two snakes after 3 mins is 4.5 inches.
What is the distance between them after 10 mins?The relative speed between them, as they are moving in the same direction, therefore,
Relative speed = (26-24.5) = 1.5 inches per minute
[tex]\text{Distance between them after 10 mins}= \rm speed \times \rm time[/tex]
[tex]= 1.5 \times 10\ mins\\= 15\ inches[/tex]
Thus, the distance between the two snakes after 10 mins is 15 inches.

A giant tortoise travels at 0.17 miles per hour and an arctic hare travels at 37 miles per hour. If
The tortoise and the hare start out together and after half an hour the hare stops to take a rest. How long does it take the tortoise to catch up
Answer:
3.145 Hours
Step-by-step explanation:
37÷2=18.5
18.5×.17=3.145
It will take the tortoise to catch up with the hare 109 hours.
Given that,
A giant tortoise travels at 0.17 miles per hour and an arctic hare travels at 37 miles per hour. If The tortoise and the hare start out together and after half an hour the hare stops to take a rest. How long it takes the tortoise to catch up is to be determined.
Speed is defined as when an object is in motion, the distance covered by that object per unit of time is called speed.
Here,
Distance traveled by hare in half hour,
= speed * time
= 37 * 1/2
= 18.5 miles
Time is taken by the tortoise to catch up with the hare,
= distance / speed
= 18.5 / 0.17
≈ 109 hours
Thus, it will take the tortoise to catch up with the hare 109 hours.

x=12 but who knows maybe
Step-by-step explanation:
if we are trying to say those lines are equal length than surely the equations must be equal value otherwise they aren't equal so we can probably set them equal to each other and solve for x right? 2x+6=3x-6 subtract 6. 2x=3x-12. subtract 3x. -1x=-12. divide by -1 so x=12.
