Answer:
(3x - 2) (4x + 1)
Step-by-step explanation:
12x² - 5x - 2
Since the first term has a coefficient, you need to multiply -2 with 12 to get -24.
Two factors that add up to -5 and have a product of -24 are -8 and 3.
12x² - 8x + 3x - 2
Rearrange the expression to find the GCF.
12x² + 3x - 8x - 2
3x (4x + 1) + (-1)2(-4x -1)
3x (4x + 1) - 2 (4x + 1)
(3x - 2) (4x + 1)
A's area is 4x3=12, B=2x3=6, so yes, A is twice the area of B
a Answer: YES
b Answer: One side doubled, the other stayed the same, so area doubled.
17
85/17 is 5 and 51/17 is 3
Answer:
answer is D.
Step-by-step explanation:
divide 2550 and 3.2 and get 796.875. multiply that by 3 and you get 2390.625.
Answer:
77
Step-by-step explanation:
For each 2 evergreens there are 7 other trees.
Add 2 +7 = 9.
For each 7 non-evergreens there are 9 trees of all types.
The ratio of non-evergreens to total trees is 7/9.
Let x = number of non-evergreens.
7/9 = x/99
9x = 7 * 99
Divide both sides by 9.
x = 7 * 11
x = 77
