(12) The perimeter of the four shaped figure is 12x - 10

(13) The perimeter of the rectangle is 18x + 10

(14) The perimeter of the hexagon is 24x

Step-by-step explanation:

(12) The perimeter of the four shaped figure is calculated as;

P = (x )  +   (3x + 2)    +  (6x - 17)   +  (2x + 5)

Collect like terms together, in order to simplify the expression

P = (x + 3x + 6x + 2x) + (2 - 17 + 5)

P = 12x - 10

(13) The perimeter of the rectangle is calculated as;

P = 2( L + B)

P = 2L + 2B

Where;

L is length of the rectangle

B is the breadth of the rectangle

P = 2 (6x + 5) + 2(3x)

P = 12x + 10  + 6x

P = 18x + 10

(14) The perimeter of the hexagon is calculated as;

P = 6L

Where;

L is length of each side

P = 6 (4x)

P = 24x

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 : )

i you goofed up when writing this, because hnot is not a word minusf is not either. i cannot answer   because of that.
