a) $t = p^2 + 7$
b) $t = p + (p + 7)$
c) $t = p + (p - 7)$
d) $t = p - (p + 7)$
part b
b. if pietra walked 9 miles during the week, how many miles did deanna walk?
16 mi
c. if pietra walked 11 miles during the week, how many miles did the two girls walk together?
mi

Explanation:

Step1: Identify Deanna's miles

From part a, Deanna walked $p+7$ miles.

Step2: Solve part b

Substitute $p=9$: $9+7=16$

Step3: Solve part c

Substitute $p=11$ into $T = p + (p + 7)$:
$T=11+(11+7)=11+18=29$

Answer:

a. B) $T = p + (p + 7)$
b. 16
c. 29
