Does anyone know how to do this

Scilla [17]

Answer:

$7 {x}^{2} + 28x - 35 = 0$

$7 {x}^{2} + 35x - 7x - 35 = 0$

$7x(x + 5) - 7(x + 5) = 0$

$(x + 5)(7x - 7) = 0$

$(x + 5)(x - 1) = 0$

What is the answer to what X is?

solmaris [256]

Answer:

$x=3$

Step-by-step explanation:

By the exterior angle theorem,

$(45x)\degree=(57+x)\degree+(26x)\degree$

Group like terms and solve for x.

$45x-26x-x=57$

$19x=57$

Divide both sides by 19;

$x=3$
