Answer:
c. 2a3+9a2+45a+6ab2+18b2
Step-by-step explanation:
(a+3) + (−2a2+15a+6b2)
Using distributed p. with and a and 3
a(−2a2) + a(15a) +a(6b2) and 3(−2a2) + 3(15a) + 3(6b2)
= -−2a3 + 15a2 + 6ab2 = -6a2 + 45a + 18b2
Now add like terms and put in standard form.
15a2+(-6a2) = 9a2
And equals
-2a3 + 9a2+45a+6ab2+18b2
Trust me I took the test and got 100%
Your welcome,
Your answer, in your set notation, is
{-2, 7}
Answer: False
Step-by-step explanation:
398 + 9 = 407
400 + 8 = 408
If the equation was 398 + 10 then yes it will be equal to 400 + 8
7.) 6 + 9 = 15t - 6 = 9t + 2 = 11t
15t-4
Answer: A.)
8.) f^+2+3
f^5
Answer: A.)
9.)
144^14 = 1.6e30
144^220736
1.6e30/220736 = 7.9e25
/7.9e25 = 144^28
Answer: C.)
