Answer:
n = 6
Step-by-step explanation:
17n + 4n - 4 =122
combine like terms 17n & 4n
21n - 4 = 122
21n - 4 + 4 = 122 + 4
21n = 126
21n / 21 = 126 / 21
n = 6
Answer:
Step-by-step explanation:
The width is w. the length is 2w - 4. to find area we would multiply these two together: w(2w - 4) & make sure to distribute the w to the 2w AND the -4. so the answer to this question would be 2w^2 - 4w (c). hope this helps!
