Answer: Length = 13 ft. , Width = 9 ft.
Step-by-step explanation:
Rectangle area = Length x width
Area = 117 ft.
Length = x + 4
Width = x
To solve
(x)(x + 4) = 117
x^2 + 4x = 117
x^2 + 4x - 117 = 0
(x - 9)(x + 13)
x = 9, -13
x = 9 <em>(measurement cannot be negative)</em>
Length
x + 4
9 + 4 = 13

b: Project A.
Not sure about a-1, hope I helped.
Answer:
(A) x=-28
Step-by-step explanation:
237 -6x = 405 [note that 6*(-x) is (-6x)]
-6x = 168 [subtract 237 from both sides]
x = -28 [divide both sides by (-6)]
Answer:
x ≈ 3.4 cm
Step-by-step explanation:
Using the sine ratio in the right triangle
sin57° = 
= 
( multiply both sides by 4 )
4 × sin57° = x , thus
x ≈ 3.4 cm ( to 1 dec. place )
