Answer: No real solutions.
Step-by-step explanation:
If you would like to simplify Q + S - T, you can
do this using the following steps:<span>
Q = 7m + 3n,
R = 11 - 2m,
S = n + 5,
T = -m - 3n + 8
</span>Q + S - T = 7m + 3n + n + 5 - (-m - 3n + 8) = 7m + 3n + n + 5 + m + 3n - 8 = 8m + 7n - 3
The correct result would be <span>8m + 7n - 3.</span>
Answer:
Try 336
Step-by-step explanation:
14+14=28
triangle area= 12x6x28=84
rectangle area= 28x9=252
252+84= 336
answer=336
