Answer: -2a^3 + 9a^2 + 45a + 18b^2 + 6ab^2
Step-by-step explanation:
(a + 3) * (-2a^2 + 15a + 6b^2)
We open the brackets with (a + 3)
a ( -2a^2 + 15a + 6b^2) + 3(-2a^2 + 15a + 6b^2)
Opening the brackets
= a * -2a^2 = -2a^3
a * 15a = 15a^2
a * 6b^2 = 6ab^2
3 * -2a^2 = -6a^2
3 * 15a = 45a
3 * 6b^2 = 18b^2
Let's arrange those values weve gotten together ,don't forget the signs each carry
= -2a^3 + 15a^2 + 6ab^2 - 6a^2 + 45a + 18b^2
Collect the like terms
= -2a^3 + 15a^2 - 6a^2 + 6ab^2 + 45a + 18b^2
= -2a^3 + 9a^2 + 6ab^2 + 45a + 18b^2
Answer:
A.1 1/2
Step-by-step explanation:
just add the 1/4 and 1/4 and u get 2/4 which simplifies to 1/2 so u get 1 1/2
If Jeff starts with 1/2 of a pizza then eats 1/3 of it he has 2/3 of 1/2 left. Therefore if you multiply those together you get your answer.
(2/3)*(1/2)=2/6=1/3
Jeff has 1/3 of the pizza left
Answer:
3
Step-by-step explanation:
Subsitute -4 for m and 2 for p as given
( 4(2) - (-4) ) / 4
Double negatives make a positive.
( 4(2) + 4 ) / 4
Multiply inside parenthesis first
( 8 + 4 ) / 4
Add
12 / 4
3
Answer: x > 6
Step-by-step explanation: Since <em>x</em> is being multiplied by 7,
we divide by 7 on both sides of the inequality to get x > 6.
Now you should write your answer in set notation.
So we have {x: x > 6} which means that
any number greater than 6 is a solution.
