A^2 -121 = a^2 -11^2 = (a-11)(a+11)
so the second choice is right sure
Answer:
18
Step-by-step explanation:
3 multiplied by 6 = 18
Answer:
33
Step-by-step explanation:
Using Angela's method, we first multiply, then round.
V = (7.2)(3.5)(8.7)
V = 219.24
V ≈ 219
Using Brian's method, we first round, then multiply.
V = (7.2)(3.5)(8.7)
V ≈ (7)(4)(9)
V ≈ 252
The positive difference between their answers is:
252 − 219 = 33
Answer: 2x^3.
Step-by-step explanation:First, we can simplify the 12/6 to 2/1 by factoring our 6. Next, remember that when we divide the same base with different exponents, we subtract the exponents. Thus, x^5/x^2 = x^(5-2) = x^3. Thus, the answer is 2x^3.
Answer:
X=4 (Try and make a diagram with it know that you have the steps of how to do it.)
Step-by-step explanation:
3x+18=30
3x=12
x=4
