Select all expressions that are equivalent to each other. A. 3^(2+2)
B. 3 ^(2+2x)
C. 9(3)^2x
D. (3^2 x 3)^x
E. (3x3+)^2

7! = 7×6×5×4×3×2

3! = 3× 2

as 7! is multiple of 3! because 7! contains 3! that is 3× 2 as factor

so 7! /(3! ) = 7× 6× 5× 4

= 42 × 20

= 840

its b) 840✌✌✌

the answer is 489

step-by-step explanation:

answer: y=4000x+14000

step-by-step explanation:

for this case we have by definition, if two lines are perpendicular, then the product of their slopes is -1.

then, given the following line:

so,

we are looking for m_ {2}:

then, the line is given by:

we find "b" replacing the given point:

finally, the equation is:

option c
