Answer:
(5x + 7y)² = 25x² + 70xy + 49y²
Step-by-step explanation:
(5x + 7y)² = 25x² + 70xy + 49y²
Because,
(5x + b)² = (5x)² + 2(5x)(b) + b²
2(5x)(b) = 70xy
b = 7y
b² = (7y)² = 49y²
Answer:
3
Step-by-step explanation:
8x + 7 = 31 Subtract 7 from both sides
<u> -7 -7</u>
8x = 24 Divide by 8
8x/8 = 24/8
x = 3
5(x + 10) + x
First, expand. / Your problem should look like: 5x + 50 + x
Second, gather like terms. / Your problem should look like: (5x + x) + 50
Third, simplify. / Your problem should look like: 6x + 50
Answer: 6x + 50 (C)
