Answer:
see below (I hope this helps!)
Step-by-step explanation:
9) We know that the perimeters of the square and triangle are equal so to find x, we can write:
4(x - 5) = x + x + 12
4x - 20 = 2x + 12
2x = 32
x = 16
10) To find the perimeter, we can substitute x = 16 into 4(x - 5) which would be 4(16 - 5) = 4 * 11 = 44.
first factor out -4
-4(x^2 + 7x + 12)
then you can factor what is in parenthesis
-4(x+4)(x+3)
9514 1404 393
A congruent
In similar polygons, corresponding sides are proportional, and corresponding angles are <em><u>congruent</u></em>.
b is the answer I believe so because it have to be greater than 0
I hope it's right and if not my bad
