Answer:
72
Step-by-step explanation:
12 6 times
Step-by-step explanation:
0.25 = one quarter - 2/8
3/8 is spent on food
so this leaves 3/8 for savings
therefore we know that $18.27 is 3/8 of her total allowance
so
18.27 ÷ 3 = 6.09
6.09 × 8 = 48.72
thus her total allowance must have been $48.72
Answer:
(2x+1) (2x-7)
Step-by-step explanation:
Multiply the coefficient of the first term by the constant 4 • -7 = -28
Find two factors of -28 whose sum equals the coefficient of the middle term, which is -12
( -28 + 1 = -27
-14 + 2 = -12 )
Rewrite the polynomial splitting the middle term using the two factors found in step 2 above, -14 and 2
4x2 - 14x + 2x - 7
Add up the first 2 terms, pulling out like factors :
2x • (2x-7)
Add up the last 2 terms, pulling out common factors :
1 • (2x-7)
Add up the four terms :
(2x+1) • (2x-7)
