Answer:
40 = d+q
7.15=0.10d+0.25q
there are 19 dimes and 21 quarters.
Pretty sure the answer is 18
3^2+3^2=9+9=18 (with a square root)
A(x - x₁)(x - x₂) = 0
a=5, x₁=-3, x₂ = 3
so:
5(x-(-3))(x-3)=0
5(x+3)(x-3)=0
5(x²-9) = 0
5x² - 45 = 0 ← answer
1. Yes because of the constant and coefficient if you add it. Like the answer is 5m +4.
