For this case we have a quadratic equation of the form:

Where:

We find the roots:

The roots are:

Answer:

Answers:
1. gh = -21
2. g^2 - h = 46
3. g + h^2 = 2
4. g + h = -4
5. h - g = 10
6. g - h = -10
Step-by-step explanation:
1. -7 x 3 = -21
2. -7^2 = - 49
-49 + 3 = -46
3. 3^2 = 9
-7 + 9 = 2
4. -7 + 3 = -4
5. 3 - -7 = 3 + 7 = 10
6. -7 - 3 = -10
Answer:
Part A: 40% are pennies
Part B: NIckels 10, Quarters 20, Pennis 20
Step-by-step explanation:
(2(x+y)÷(x+y)(x-y) )×(x+y÷(x^2+2×x×2y+2y^2)
2÷x^2+2y^2
Answer:
