Which expression is equivalent to 63 + 27? A. (9 x 7)(9 x 3)
B. 9(7 + 3)
C. (9 + 7)(9 + 3)
D. 9 + (7 X 3)

A. (9x7)

Step-by-step explanation:

A. ( 9 x 7 ) = 63 and ( 9 x 3 ) = 27 (correct answer)

B. ( 7 + 3 ) = 10 and then 10 x 9 = 90 (incorrect answer)

C. ( 9 + 7 ) = 16 and ( 9 + 3 ) = 12 (incorrect answer)

D. ( 7 x 3 ) = 21 and then 9 + 21 = 24 (incorrect answer)

I hope this helps :)

10 you would take 50/ .2

step-by-step explanation:

i think something is missing in your question because y-1=(x-12) would not pass through the point (-4,-3). because if you replace x by -4 your are supposed to find y=-3 which is not the case her. if you replace x by -4 you find =-15.

i assume the right equation is y-1=1/4*(x-12) because this one is passing through both your points (if you are interested to know how i found that out i can tell you).

in this equation if i replace x by -4 i find y=-3 and if i replace x by 12, i find y=1 so the line representing this equation is passing through those 2 points.

then the standard form of the equation is finding an expression of y in function of x

y-1=1/4*(x-12)

y=x/4-3+1

y=x/4-2

hope that .

do you confirm there was a mistake in the question?
