Use the zero product property to find the solutions to the equation x^2 + x -30=12

Alla [95]

Answer:

The solutions are x = -7, 6.

Step-by-step explanation:

To find the solutions, move everything to one side of the equation so the equation is equal to 0. Then factor. Set the factors equal to 0 and solve for x.

$x^2 + x - 30 = 12\\x^2 + x -42=0\\(x+7)(x-6) = 0$

x+7 = 0

x = -7

and

x-6 = 0

x = 6

The solutions are x = -7, 6.

Find angle sum therom

Allisa [31]

♥️♥️♥️♥️♥️♥️♥️♥️♥️♥️♥️♥️♥️♥️

Sum of the interior angles of any triangle is 180° .

Thus ;

$y + 48° + 90° = 180°$

$y + 138° = 180°$

Subtract sides 138°

$y + 138° - 138° = 180° - 138° \\$

$y = 42°$
