Answer:
Greatest common factor = [2x - 5][x + 2]
Step-by-step explanation:
Given equation:
2x² - x - 10
Find:
Greatest common factor
Computation;
⇔ 2x² - x - 10
By splitting mid term
⇔ 2x² - [5 - 4]x - 10
Multiply by 'x'
⇔ 2x² - 5x + 4x - 10
taking x and 2 as common
⇔ x[2x - 5] + 2[2x - 5]
taking [2x - 5] as common
⇔ [2x - 5][x + 2]
Greatest common factor = [2x - 5][x + 2]
Answer:
x = 8
Step-by-step explanation:
-4 + 8x = 6x + 12
Subtract 6x from both sides
-4 + 2x = 12
add 4 to both sides
2x = 16
x = 8

Answer:
44%
Step-by-step explanation:
If p represents the number of portions and q represents the quantity in each portion, then the original amount needed was p·q.
After p is increased by 20%, its number is ...
p + 0.20·p = 1.20·p
After q is increased by 20%, its amount is ...
q + 0.20 ·q = 1.20·q
Then the new amount the parents must buy is ...
(1.20p)(1.20q) = 1.20²·pq = 1.44pq
This amount is ...
(1 + 44/100)·pq = pq + 44%·pq
It is 44% more than the original planned purchase.
