Pentagon G was dilated from the origin by a scale factor of one half to create Pentagon G′. Which statement explains why the pentagons are similar? Dilations preserve side length; therefore, the corresponding sides of pentagons G and G′ are congruent. Dilations preserve betweenness of points; therefore, the corresponding sides of pentagons G and G′ are proportional. Dilations preserve orientation; therefore, the corresponding angles of pentagons G and G′ are congruent. Dilations preserve collinearity; therefore, the corresponding angles of pentagons G and G′ are congruent.

step-by-step explanation:

always plug in x. in this case, x equals 4.

i'm going to first solve 4(2+3x)

1) 4(2+3(4)) use pemdas to solve.

i'm going to multiply whats in the parenthesis first, so 3 times 4=12.

2)4 (2+12) i'm then going to multiply 4 by both numbers in the parenthesis (because multiplying comes before adding)

4 times 2= 8.   4 times 12= 48

4) (8+48)= 56 (answer)

i'm then going to solve 8+12x and plug in 4 for x.

1) 8 +12(4)

multiplying comes before adding, so i'm gonna multiply 12 and 4.

12 times 4= 48.

2) 8+48=56

both equal the same!

8+10

step-by-step explanation:

you multiply 4 by 2 and 5 by 2

x = 12

y = 1

for the points!
