The value of x = 5

Step-by-step explanation:

Given

ABCDE ~ FGHJK

It means the polygon is similar.

Similar polygons have the same shape but different sizes.

Thus, the given two polygons will have their corresponding sides are in proportion.

so

AB/AE = FG/FK

here

AB = 4, AE = x, FG = 8, FK = 10

so substituting AB = 4, AE = x, FG = 8, FK = 10

4/x = 8/10

8 × x = 4 × 10

8x = 40

divide both sides by 8

8x/8 = 40/8

x = 5

Therefore, the value of x = 5

10a^3+277a^2-132a-792

step-by-step explanation:

(2a+11)(5a-12)(foil)

=10a^2-24a+55a-132 =10a^2+31a-132

(10a^2+31a-132)(a+6)

=10a^3+60a^2+31a^2+186a^2-132a-792 =10a^3+277a^2-132a-792

i hope this is what you are looking for : )
