Answer:
First Equation is Right which is -56/8 = 7
Step-by-step explanation:
LHS = -56/8
=> -7
RHS = -7
So LHS = RHS
If the length of the ladder is x then 12/x=cos70, so x=12/cos70=35’ approx, answer c.
Answer:
D) 1
Step-by-step explanation:
using the distributive property we have ax+a+bx-b-2=0. because the equation is true for all real x, ax=-bx. this means a-b-2=0 and a=-b. a-b-2=0 becomes a=b+2. then we substitute a for -b and get -b=b+2 which becomes 2b=-2 so b=-1. since a=-b, a=1

f(x) = 2x
g(x) = x + 3
First let us find (fog)(x)
(fog)(x) = f(g(x)
= f(x+3)
= 2(x+3)
= 2x + 6
==> (fog)(x) = 2x + 6
Now let us find (gof)(x):
(gof)(x) = g(f(x)
= g(2x)
= 2x + 3
==> (gof)(x) = 2x + 3
Step-by-step explanation:
Width: x
Length: 3x
Perimeter=x+x+3x+3x=8x
8x=400
