You FOIL the binomials out to get a quadratic.
Answer:
x = -8
Step-by-step explanation:
1) 5x + 7= 7x +23
Move the terms
2) 5x + 7 -7x = 23
Collect like terms
3) 5x -7x = 23 - 7
Calculate
4) -2x = 16
Divide both sides by <em>-2</em>
5) x = -8
It’s 7 in that’s the only answer that makes sense
PEMDAS means we do exponents before we multiply.
10 ^ 7 = 10,000,000
(10 * 10 * 10 * 10 * 10 * 10 * 10)
5.8 * 10,000,000
= 58,000,000
