Answer:
7.3
Step-by-step explanation:
You have to make this a pythagorean theorm equation.
so you would have a side length of 7 and 2.
7^2+2^2=c^2
49 + 4 = c^2
53 = c^2
sqrt:53
7.28010
round
7.3
Answer:
The correct answer is D.
Step-by-step explanation:
You got it!
15 - x = 2(x + 3)
15 - x = 2x + 6
15 = 3x + 6
9 = 3x
3 = x
x = 3
Answer:
Perimeter = (Length x 2) + (Width x 2)
27.5 = (9 x 2) + (Width x 2)
27.5 = 18 + (Width x 2)
9.5 = (Width x 2)
4.75 = Width
check:
27.5 = (9 x 2) + (4.75 x 2)
27.5 = 18 + 9.5
27.5 = 27.5
Since the width is 4.75 and the length is 9, we can multiply the two to get the area. 4.75 x 9 = 42.75 sq. ft.
