Answer: x=-11  x=5

Step-by-step explanation:

<h3>(x+3)^2=72-8</h3><h3>(x+3) (x+3) = 64</h3><h3>x(x+3) +3(x+3) = 64</h3><h3>x^2 +3x+3x+9=64</h3><h3>x^2+6x+9=64</h3><h3>0=x^2+6x+9-64</h3><h3>0=x^2+6x-55</h3>

ok you look for two numbers that will multiply to -55 and also when added or subtracted it will give +6 and those 2 numbers where:

<h3>11*-5= -55    11 -5 =6</h3><h3>0=(x+11) (x-5)</h3><h3>x+11=0        x-5=0</h3><h3>x= -11           x= 5</h3><h3>YOU CAN GRAPH IT ON DESMOS TO FIND YOUR X-INTERCEPTS</h3>

Answer:

x = 23

y = 110

Step-by-step explanation:

70 and  3x+1 are alternate exterior angles and that means they are equal

70 =3x+1

Subtract 1 from each side

69 = 3x

Divide by 3

69/3 =3x/3

23 =x

70 and y are same side exterior angles and that means they are supplementary ( add to 180)

70+y = 180

y = 180-70

y = 110
