Answer:
a.) 
Step-by-step explanation:
Factor 
Find what two numbers add up to 16, and equal 60 when multiplied:
and 

Factor:

<em>Finito.</em>
Perimeter is the addition of all the sides
x-2+x+3x+1=2x-5+x+4+6x-7; since their perimeters are equal
5x-1=9x-8
collect the like terms
-1+8=9x-5x
7=4x
x=7/4
x=1.75

Answer:
x = ± 10
Step-by-step explanation:
To solve the equation let y = 0 , that is
0 = 100 - x²( add x² to both sides )
x² = 100 (I take the square root of both sides )
x = ±
= ± 10
Then solution is x = - 10, x = 10
