Solve for x.
5(x - 10) = 30 - 15x
Ox=1
O x= 4
O x=5
O x = 8

a)x=60

b)x=0

c)=50

Step-by-step explanation:

5(1-10)=30-15

5(-9)=15

-45=15

=15+45

=60

x=60

5(4-10)=30-60

5(-6)=-30

-30=-30

=-30+30

x=0

d. it is a convex pentagon because it has five sides and none of the sides would extend into the inside of the polygon.

step-by-step explanation:

if a = 1,   and b = 2, then the answer is 47.99999999. if you round that to the nearest whole number, the answer is 48.
