The first integer is going to be x and the second one is going to be y.
We now turn the clues into equations:
x = y - 5
xy = 84
The substitution method:
(y - 5)y = 84
y^2 - 5y - 84 = 0
(y+7)(y-12) = 0
y = -7, 12.
If y = -7, then x = -12.
If y = 12, then x = 7
Answer:
Step-by-step explanation:
<u>Order of operations, use the operation within the parenthesis:</u>
<u>Distributive property, a(b + c) = ab + ac:</u>
- 1) 4*5 - 4*2 = 20 - 8
- 2) 20 - 8 = 12
Both ways are correct and lead to same result
Answer:
8

3x-7-2x+5x=
6x-7
Answer:
2(2x-5)(2x+5)
Step-by-step explanation:
I think you meant to say 8x^2-50. If so then factoring this down should be easy. Since there is no x value in the middle the equation will have a positive and a negative number. This is also a perfect square therefore, this factors down to: 2(2x-5)(2x+5).
