To find an improper fraction, you want to do 18* 7 which equals, 126, so then 126+4=130. So then 130/7 would be your answer.
Answer:
a³ - a² - 3a+ 6
Step-by-step explanation:
we are asked by how much does (a³-2a) exceed (a²+a-6)
in other words, we are being asked to find the difference between the 2 terms above.
Mathematically we are asked to find:
(a³-2a) - (a²+a-6) (expand parentheses by distribution property)
=(a³-2a - a²- a + 6)
= a³ - a² - 3a+ 6 (answer)
Answer:
a = - 3
Step-by-step explanation:
The equation has common factors x(x + 3) on both sides
For the 2 sides of the equation to be equal, then the factor
(x + a) = (x - 3) and by comparison
a = - 3
3/5(15d+20)−1/6(18d−12)=38
Simplify
3/5(15d+20)−1/6(18d−12)=38
(3/5)(15d)+(3/5)(20)+−3d+2=38(Distribute)
9d+12+−3d+2=38
(9d+−3d)+(12+2)=38(Combine Like Terms)
6d+14=38
Subtract 14 from both sides.
6d+14−14=38−14
6d=24
Divide both sides by 6.
6d/6 = 24/6
d=4
