J (22hrs)

Step-by-step explanation:

812 divided by 14= 58

1,276 divided by 58= 22 hrs

1) Transform the polynomial into a perfect square trinomial to solve. 3x^2+24x=27
a) {-21, -11}
b) {-29,21}
c) {-41,9}
d) {-1,1}

Answers

If you would like to solve 3 * x^2 + 24 * x = 27, you can do this using the following steps:

3 * x^2 + 24 * x = 27
3 * x^2 + 24 * x - 27 = 0
3 * (x^2 + 8 * x - 9) = 0
x^2 + 8 * x - 9 = 0
(x + 9) * (x - 1) = 0
1. x = - 9
2. x = 1

None of the above results is correct. The correct result would be {-9, 1}.

What two numbers add up to 20 but multiply to 75?

Answers

First you find all the numbers that multiply to get 75.

75 x 1
25 x 3
15 x 5

Then find out which two add together to get 20.

75 + 1 = 76
25 + 3 = 28
15 + 5 = 20

So the answer would be 15 and 5.
15 and 5 because 15 times 5 is 75 and 15 plus 5 is 20
