Hello!

8c - 3c + 3 = 13
Begin by combining like terms:
5c + 3 = 13
Subtract 3 from both sides:
5c + 3 - 3 = 13 - 3
5c = 10
Divide both sides by 5:
5c/5 = 10/5
c = 2.
Answer:
B and C
Step-by-step explanation:
Jane found multiples of 8 instead of factors and should've gotten 1, 2, 4, and 8 as her answer.
Hope this helps :)
Because if it is linear it is a straight line so the slope must always be equal to eachother
My triangle solver says EF ≈ 7.5 ft.

The law of cosines is usually used for this.
EF^2 = DE^2 +DF^2 -2*DE*DF*cos(D)
.. = 6^2 +11^2 -2*6*11*cos(40°)
.. ≈ 55.88
EF ≈ √55.88 ≈ 7.5 . . . ft
