Solve for x
x=5
x=18
x=30
x=36

x=36

step-by-step explanation:

3x+2x=180

5x÷5=180÷5

x=36

these angles are supplementary. meaning that there sum is 180 degrees. knowing this you can make a formula of the two angles being summed and set equal to 180. from here you can solve for x

3x + 2x = 180

first combine like terms (3x and 2x)

5x = 180

next divide 5 to both sides to finish isolating x. since 5 is being multiplied by x, division (the opposite of multiplication) will cancel 5 out (in this case it will make 5 one) from the left side and bring it over to the right side.

5x/5 = 180/5

d . x = 36

hope this !

step-by-step explanation:

substitution for (0,1)

y=x^2+4x+1

1=0^2+4(x)0+1

1=0+4(x)0+1

1=4(x)0+1

1=0+1

1=1

substitution for (-3,-2)

y=x+1

-2=-3+1

-2=-2
