Pythagorean theorem
a^2 + b^2 = c^2
c = longest side
a^2 + 13^2 = 20^2
a^2 + 169 = 400
a^2 = 231, a = squareroot 231

Solve the equation.
elena55 [62]

Answer:

C: x=-3 or x=4

Step-by-step explanation:

To solve the equation x^2-x-12=0 we need to factor it

We are looking for two numbers that when multiplied give -12 and when added give -x

This means that when factored, the equation would be (x-4)(x+3)=0

Now we can set each of these equal to 0, which means that at

x=-3 and x=4 , the equation will equal 0

PLEASE HELP!
RUDIKE [14]

3x^2 + 23x - 8 can be factored into (3x - 1)(x + 8). To double-check, you can multiply the terms together again using FOIL: first, outside, inside, last.


(3x)(x) + (3x)(8) + (-1)(x) + (-1)(8)


3x² + 24x - x - 8


3x² + 23x - 8


Check.
