PLEASE HELP ITS MY TRIMESTER TEST MY MOM WILL KILL ME IF I FAIL! <3 WILL MARK BRAINLIST!

B

Step-by-step explanation:

we have all the sides of the parallelogram, we just need to find the circumference of the semicircle and the diameter is already given. so the final equation should look like this:

(18 x 3.14 ÷ 2) + 27 + 18 + 27 = 100.26

in this case, i took pi as 3.14 because when i used the actual pi number, my answer was 100.27, so i used 3.14.

hence, the answer is B which is 100.26 inches

the entire expression should be subtracted from 30. to subtract the quantity, distribute the negative sign, which changes the signs on the terms. so, the –2 changes to positive and gets added to 30 instead of subtracted from it.

hope this ! ^w^

step-by-step explanation:

let

we know that

the y-intercept is the y-coordinate of the point when the value of x is equal to zero

so

the y-coordinate of the point a is the y-intercept

the answer part a) is

the value of y-intercept is

part b) find the slope m

we know that

the value of the slope is equal to

substitute the values

therefore

the answer part b) is

the value of the slope is equal to

the general answer is

the slope is

the value of y-intercept is
