Answer:
45
Step-by-step explanation:
9 times 5=45
Answer:
45
Step-by-step explanation:
We can first expand the expression:
n(n+p) - n
= n^2 + np + n
Then, we can plug in values of n and p into the expression:
n^2 + np + n = (5)^2 + (5)(3) + 5 = 25 + 15 + 5 = 45
D:devaughn
S:sydney
D+S=83. First equation
D=S-9. Second equation
D-S=-9
Add 2 equations
D+S+D-S=83-9
2D=74
D=37
Devaughn is 37 years old
So
D+S=83
37+S=83
S=46
Sydney is 46 years old
