Answer:
n^2 - n - 12 = (n+3)(n-4)
Step-by-step explanation:
3 times - 4 = -12 ( two numbers when multiplied = -12, when added=-1)
3 + -4 = -1
Answer:
B
Step-by-step explanation:
The mass of the solution is 190 g - 120 g = 70 g. Thus, it's density is 70 g / 50 mL = 1.4 g/mL.
A = bh
b = 7 + 4 = 11
h = 8
11(8) = 88
The correct answer is B. 88 m^2
