Solve by factoring 25x^2+5x-12=0

x = -4/5 and x = 3/5.

Step-by-step explanation:

The coefficient of x^2 is 25, which is 5 * 5. 5 * -3 = -15, and 5 * 4 = 20. 20 - 15 = 5.

So...

25x^2 + 5x - 12 = 0

(5x + 4)(5x - 3) = 0

5x + 4 = 0

5x = -4

x = -4/5

5x - 3 = 0

5x = 3

x = 3/5

So, x = -4/5 and x = 3/5.

Hope this helps!

answer:

1. 0.04

2. 0.15

step-by-step explanation:

i just finished that assignment for properties of probability distributions.

location: point 0

step-by-step explanation:

well, -8 to 10 on a number line is 18 spaces.

1/9 of 18 is 2.

so, 4/9 of 18 must be 8.

8 spaces from -8 (a) is 0.

so, 4/9 of the way from -8 to 10 is 0!
