Answer:
B= y+2w
Step-by-step explanation:
We can see that A= y+3w, so because B is missing one of the w's, the area must be y+2w.

x ≈ 1.09
Answer:
k = -3.5
Step-by-step explanation:
6k ÷ 7 = -3
Multiply 7 to both sides
6k = -21
Divide both sides by 6
6k/6 = -21/6
k = -3.5
To check if the answer is correct or not, you can always plug in -3.5 for k in the equation.
6(-3.5) ÷ 7 = -3
-21 ÷ 7 = -3
-3 = -3
-3 equals -3 so it is correct that k = -3.5
If you use the distributive property on (x+y)/3, the result should be:
(x/3) + (y/3)
