<span>Let's assume the mat as a right triangle
Taking length of triangle be x
so height = x-21
and hypotenuse= x+6
for right triangle we can apply pythagoras theorem
so (x+6)^2=x^2+(x-21)^2
expanding we get
x^2 + 12 x + 36 = 2 x^2 - 42 x + 441
solving for x we get
x=9,45
But for length to be 9 height will be negative
So the length of mat will be 45 inches</span>

Answer:
first graph
Step-by-step explanation:
Answer:
w = 18
Step-by-step explanation:
Given
(w + 18) = 12 ← distribute parenthesis on left side
w + 6 = 12 ( subtract 6 from both sides )
w = 6 ( multiply both sides by 3 to clear the fraction )
w = 18
