If the length of the ladder is x then 12/x=cos70, so x=12/cos70=35’ approx, answer c.
The formula of the line is
y=mx + b
The likes goes through the point (0,0)
that means that y-int = 0, b=0
y=mx
So we need to find only slope.

Answer:
422 in.2
Step-by-step explanation:
Substitute the measurements of the rectangular prism into the formula SA = 2(lw) + 2 (lw) + 2(lh): 2(13)(7) + 2(6)(7) + 2(13)(6) = 422 in2.
Answer:
(4x² + 24x + 35) in²
Step-by-step explanation:
(5+2x)(7+2x)
35 + 14x + 10x + 4x²
4x² + 24x + 35
