we have
(a+b)(3a-b)(2a+7b)
step 1
Solve
apply distributive property
(a+b)(3a-b)=3a^2-ab-3ab-b^2=3a^2-4ab-b^2
step 2
Multiply (3a^2-4ab-b^2) by (2a+7b)
6a^3+21a^2b-8a^2b-28ab^2-2ab^2-7b^3=6a^3+13a^2b-30ab^2-7b^3
answer is
<h2>6a^3+13a^2b-30ab^2-7b^3</h2>
Answer:
It's either 35 x10^(-13) or 3.5 x10^(-13)
Step-by-step explanation:
35 x 10^(-13) = 3•5 x 10 x 10^(-13)
3•5 x 10 x 10^(-13) = 3•5 x 10^(-12)
Hope I'm correct
Answer:
1/2
Step-by-step explanation:
This midpoint is found by averaging -4 and 5:
-4 + 5
---------- = 1/2

Answer:
11,813
Step-by-step explanation:
PEMDAS
(20x20x30) - 90 + 90 -187 = 12,000
12,000 - 90 + 90 = 12,000
+ 90 and - 90 cancel each other out.
12,000 - 187 = 11,813
Hope this helps!
