Answer: The correct answer is Choice C.

For this polynomial to be a perfect square, it would need to be:
(10x + 7)^2

This will ensure that the first terms and the last terms will be 100x^ and 49. However, if you use foil to multiply the factors, you will not get 150x for the center term. Choice C also states that 150x will not be the middle term.

liq [111]
<span>y = 2x + 20. The answer is A. Explanation: Vlad spends a known amount of time on his history homework (20). On top of it, he also spends an unknown amount of time on solving a number of math problems (x). Each problem takes two minutes to solve, so the amount of time that he spends solving math problems is 2*x or 2x. In total (y), Vlad spends 20 + 2x amount of time on his homework. So y = 2x + 20, where y is clearly greater or equal to 20 and x is greater or equal to 0.</span>

timurjin [86]

Answer:

common denominator of 1/a + 1/b is  ab

however simplifying the complex fraction gives:   (b-a)/(b +a)

Step-by-step explanation:

common denominator of 1/a + 1/b

should be the product of the denominators

a*b

so   1/a  + 1/b =   (b + a)/ab

ao

( 1/a  - 1/b)  divided by (1/a + 1/b) =  (b - a)/(ab)  divided by (b+a)/ab
