Answer:
a) 4
b) 
Step-by-step explanation:
<u>PART A</u>
Simplify the expression by solving out the square roots.
= 
You can cancel out the
on the top and bottom.
So, a should be 4.
<u>PART B</u>
Solve out the square root. The square root is pretty much the 1/2 power, so you can divide the exponents by half.
= 
You can subtract exponents to divide them. So the y variable becomes
, or
.
Then, the overall expression is
, or you can turn that into
.
Answer:
Step-by-step explanation:
The given equation passes through the origin:

The segment passes through the point (-2,6)
So the equation will become 
The perimeter of the rectangle is 2(2x+5), and the perimeter of the triangle is x+7+x+4+x+11, which simplifies to 3x+22.
Therefore...
3x+22=4x+10
x=12
The perimeter of the rectangle is 2(2(12)+5)=2(24+5)=2(29)=48.
a. x=12
b. The perimeter of each figure is 48.
