Answer:
B
Step-by-step explanation:
5a^2 - 44 = 81 Add 44 to both sides
5a^2 = 81 + 44 Collect like terms
5a^2 = 125 Divide both sides by 5
a^2 = 125/5
a^2 = 25 Take the square root of both sides
√a^2 = √25
a = +5
a = -5
The answer is B
<B+<D = 180
x+148 = 180
x = 32
<A = 2(32) + 1
<A = 64+1
<A = 65
Answer:
2x(x − 3)(x + 3)
x(x + 4)(x + 2)
Step-by-step explanation:
2x³ − 18x
x(2x² − 18)
2x(x² − 9)
2x(x − 3)(x + 3)
x³ + 6x² + 8x
x(x² + 6x + 8)
x(x + 4)(x + 2)
