Suppose A and B represent two different schools populations where A>B abd A and B must be greater than 0. Which of the follow
ing expressions is the largest? Explain why. Show all work necessary.
A.2(A+B)
B. A+B^2
C. A^2+B^2
D. A^2-B^2
1 answer:
Hmm, one way we can do this is by assigning numbers to each
A=4 and B=3
A>B because 4>3
so
A. 2(A+B)=2(4+3)=2(7)=14
B. A+B^2=4+3^2=4+9=13
C. A^2+B^2=4^2+3^2=16+9=25
D. A^2-B^2=4^2-3^2=16-9=7
the largest is 25 so C

The answer is t ≤ 11.
- Subtract 10 from each side.
- 21 - 10 ≥ t + 10 - 10
- t ≤ 11
Answer:
Step-by-step explanation:
y = a(b)^x
a would represent the initial value.
b would represent the change
x represents the number of years
y = 805(0.9)^6
y = 805(0.531441)
y = 427.8
y = 427 cheetahs
