Find the solution of -x-2-10x=25

x = -5

Step-by-step explanation:

start with factoring

-x^2 - 10x - 25 = 0 (i moved 25 to the left side)

then you can multiply the entire equation by -1 to get rid of the negative sign

x^2 + 10x + 25 = 0

now 5x5 = 25 and 5+5 = 10.

so (x^2 + 5x + 5x + 25) = 0

x(x+5) 5(x+5) = 0

(x+5)(x+5) = 0

(x+5)^2 = 0

so x = -5

the ratio of white tiles to blue tiles is 48: 16. the ratio in it's simplest form is 3: 1.

step-by-step explanation:

ratio: take the first number and add a colon next to it, then add the second number after that. make sure the ratio order matches up with the written problem!

simplest form: we can simplify the ratio 48 : 16 by dividing both terms by the greatest common factor (gcf).

the gcf of 48 and 16 is 16.

divide both terms by 16:

48 ÷ 16 = 3

16 ÷ 16 = 1

reducing to simplest form:

48 : 16 = 3 : 1
