Answer:
a^3 + a^2
Step-by-step explanation:
Distribute the term left of each set of parentheses, then combine like terms.
-a²(3a - 5) + 4a(a² - a) =
= -3a^3 + 5a^2 + 4a^3 - 4a^2
= a^3 + a^2
I think 42
would be the best answer to your question in my opininon.
Answer:
Step-by-step Solution:
Simply change the denominators such that both denominators are the same. Then, add the fractions to get your result.
- 1/2 + 1/6
- => 3 x 1/2 x 3 + 1/6
- => 3/6 + 1/6
- => 4/6 = 2/3
Hence, the solution is 2/3.
Answer:
(21, 17 )
Step-by-step explanation:
Using the midpoint formula and equating to the coordinates of the midpoint.
Let endpoint 2 have coordinates (x, y ), then
0.5(x - 3) = 9 ( multiply both sides by 2 )
x - 3 = 18 ( add 3 to both sides )
x = 21
and
0.5(y - 5) = 6 ( multiply both sides by 2 )
y - 5 = 12 ( add 5 to both sides )
y = 17
endpoint 2 = (21, 17 )
