Given f (x) = 3-1 and g(x) = x² + 2. Elijah was asked to find f (g(x)). He showed the following work:
Line 1: ſ (g(x)) = f (x + 2)
Line 2:
7
3(x2+2)
Line 3:
7
3x2+6
This answer is incorrect. Answer the following questions:
A. On which line did Elijah make a mistake? Justify your answer. (5
points)
B. Now show the correct way to solve this problem, showing all work
like Elijah did above. (5 points)

b is 38 degrees.

a is 52 degrees.

this is because if b is 38 and a is 14 degrees more than b than 38+14=52 and 52+38=90 degrees. hope this .

the smallest possible measurement of the width is 14 feet

step-by-step explanation:

let's assume length of parallelogram is 'l'

width of parallelogram is 'w'

the perimeter of a parallelogram must be no less than 40 feet

so, we get

we are given

length of parallelogram is 6 feet

so,

l=6

we can plug it

now, we can solve for w

subtract both sides by 12

divide both sides by 2

and we get

so,

the smallest possible measurement of the width is 14 feet
