Answer: What is the distance from 0 on a number line called?
The distance between a number's place on the number line and 0 is called the number's [absolute value]. To write the absolute value of a number, use short vertical lines (|) on either side of the number.
Step-by-step explanation:
Here's a hint. I hope this helps.
32/3.2 = 3.2c/3.2
c = 32/3.2
c = 10
Answer:
7-x
Step-by-step explanation:
49 - x^2 is a perfect square so
it factors to :(7+x)(7-x)
since there is a negative in 49 - x^2, it would make sense that the answer would be a negative to get that negative answer in the first place (negative times a positive equals a negative)
Forgive me for my lame explanation :')

The answer is in the attached file below
Step-by-step explanation:
Answer:
Assuming the area is made up of a square and a semicircle.
<u>Perimeter</u>
The side length of the square = 18 ft
We can see 3 full side lengths plus one side length from which we need to subtract 12 ft (see attached diagram).
⇒ perimeter of the square = (3 x 18) + (18 - 12)
= 54 + 6
= 60 ft
Circumference of a circle =
d (where d is the diameter)
⇒ arc length of the semicircle = 1/2 circumference
= 1/2 ·
· 12
= 6
ft
Total perimeter = 60 + 6
= 78.8 ft (nearest tenth)
<u>Area</u>
Area of a square = s² (where s is the side length)
⇒ area of square = 18²
= 324 ft²
Diameter = 2r ⇒ r = 1/2 diameter
Area of a circle =
r² (where r is the radius)
⇒ area of the semicircle = 1/2 ·
· 6²
= 18
ft²
Total area = 324 + 18
= 380.5 ft² (nearest tenth)
