Answer: The answer to this question is (2a-5)(2a+5)
Step-by-step explanation:
- Because first, you have to write the quadratic equation 4a^2-25 in exponential form
- Then, you calculate the product by multiplying the terms with equal exponents by multiplying their bases
(2a)^2-5^2
- And then last but not least, using a^2-b^2=(a-b)(a+b), factor the expression
(2a-5)(2a+5) and then there's your answer and your explanation!!!!!
Answer:
O4) x = y
Step-by-step explanation:
I took this before
<span>(2x + 1) • (4x2 - 2x + 1)
———————————————————————— 32x<span>2</span></span>
2,3,5,8,13,19 they are all going up the first one goes up by one,then, 2, 3.. etc
Cory . . . . 21/60 = 0.35 = 35 percent
Krista . . . 18/45 = 0.4 = 40 percent
Paula . . . 17/50 = 0.34 = 34 percent
From this point, I'm pretty sure you can line them up.
