Answer:
By using completing the square method, equation (x - 12) (x + 4) = 9 can be solved as x = (4 + √ 73) or (4 - √ 73)
Answer:
x = 33/3 = 11
Step-by-step explanation:
A and B are corresponding angles and are therefore equal.
Thus, A = 8x - 8 = B = 5x + 25, or
3x = 33
and so x = 33/3 = 11
Answer:
The correct answer is D) 13%
Step-by-step explanation:
To turn a decimal into a percentage, we simply multiply by 100.
0.13 * 100 = 13%
Answer:
38 - 7.6(20%) = 30.4
30.4 + 2.128(7%) rounds up to about =$32.53
your answer is B
Step-by-step explanation:
The numbers of choices in each category are multiplied together. We assume the order of paint choices matters: using color 1 in area A and color 2 in area B is not the same as using color 2 in area A and color 1 in area B.
P(7,2)*4*3*2 = 42*4*3*2 = 1008 ways
_____
P(n, k) = n!/(n-k)!
P(7, 2) = 7*6 = 42
