Answer:
3
Step-by-step explanation:
there are two solutions in the given system of two equations:
a=10; b=7 and a=7; b=10.
|a-b|=3.
Let length of shortest side be x
then length of each congruent sides = x + 1
perimeter of the triangle = x + x+1 +x + 1 = 3x + 2
perimeter of the square = 4(x-2) = 4x - 8
So we have
4x - 8 = 3x + 2
x = 10
the shortest side is 10 units long.
<u>Answer:</u>
<h2>
h(x) = 2x²+2x-3</h2>
<u>Steps:</u>
f(x) = 3x²+7x-4
g(x) = x²-5x+1
h(x) = f(x) - g(x)
h(x) = 3x²+7x-4 - x²-5x+1
h(x) = 3x²-x²+7x-5x-4+1
h(x) = 2x²+2x-3
