Answer:
(12-7x)
Step-by-step explanation:
144 − 49x²
by observation, we can see that 144 = 12² and 49 = 7²
hence we can rewrite the equation
144 − 49x²
= 12² - 7²x²
= 12² - (7x)²
recall that the expression x² - y² = (x+y)(x-y)
hence,
12² - (7x)²
= (12 + 7x)(12-7x)
(12-7x) appears in the expression above, hence 12 -7x is a factor
Answer:
B
Step-by-step explanation:
6x5=30
30x2/3=20
12*2=24
24*3=72
72*4=288
n*(x+1)
288*(4+1)
288*5=1440
Answer:
answer is c
Step-by-step explanation:
oranges in Paris are three cups and grapes and apples are about two cups. (1 11/12 cups to be exact)
the exact amount of five portions of fruit salad and fraction form is 59 / 60
No because it has to be a even number to be divisible by 2 and same goes with 5 something has to x the 2 with the number like 2/4=2 because 2x2 is 4
