If x = -2, y = 6.
To solve this quesiton, we need to find the value of y if x is equal to -2. We can do this by substiuting the value of x and then solving.
y = 2 (-2) + 10
y = -4 + 10
y = 6
First, find the length
L^2+W^2=D^2 )L for length, W for width, D for diagonal)
L^2=25^2-15^2=625-225=400
L=20
A=1/2 of L*W= (1/2)*20*15=150 square inches
