Answer:
21 - 46 x
Step-by-step explanation:
9x-(7x-5)-8(6x-2)
Distribute
9x -7x +5 -48x +16
9x-7x-48x +5+16
21 - 46 x
Answer:
70
Step-by-step explanation:
Its 70 because you see the degree is 110 so try to subtract 180 degrees by 110 and you get 70 so it's the answer
B.
This is because, the people who conduct the survey and came to the conclusion of B are making an assumption that they are too busy. This is biased because from the point of view of THEM or even the education board, this could be manipulated in such a way that is not factual.
So in a nutshell, B is bias because it is not 100% factual. Remember, it's all about perspective.
Answer:
19
Step-by-step explanation:
3^3 - (4)(2) =
= 3 * 3 * 3 - 8
= 27 - 8
= 19
Answer:
C x=6
Step-by-step explanation:
sqrt(x+3) = x-3
Square each side
(sqrt(x+3))^2 = (x-3)^2
x+3 = (x-3)^2
x+3 = (x-3)(x-3)
FOIL
x+3 = x^2 -3x-3x+9
Combine like terms
x+3 = x^2 -6x+9
Subtract x from each side
x-x+3 = x^2 -6x-x +9
3 = x^2 -7x +9
Subtract 3 from each side
3-3 = x^2 -7x +9-3
0 = x^2 -7x+6
Factor
0 = (x-6)(x-1)
Using the zero product property
x-6=0 x-1 =0
x=6 x=1
Since we squared we need to check for extraneous solutions
x=1
sqrt(1+3) = 1-3
sqrt(4) = -2
2=-2
False
Extraneous
x=6
sqrt(6+3) = 6-3
sqrt(9) = 3
3=3
True solutions
