my answer is b. is this correct?
B is not correct.
78 – 5 + 7 = 80
78 – 5 + 7 = 80
The answer is A. Because the total amount of yards AFTER he ran 5 and 7 yards is 78, but they ask what expression show how many yards the running back had BEFORE the two runs so the answer is A. Because you have to subtract 5 and 7 from the end score to figure out what he had BEFORE the last two runs.
11\left[\frac{\left(9^{2}-5\right)}{2^{2}+8}\right]
