Which answer choice represents the difference of 20 and 3 times a number? A. 3j + 20
B. 20(3j)
C. 20 – 3j
D. (20 · 3)j

C

Step-by-step explanation:

The word “difference” tells us that this is a subtraction problem

the words “three times a number” tells us that the variable will be multiplied by three

therefore it is C, 20-3j

it would be 6xy and -16xy.

step-by-step explanation:

two pairs of adjacent sides are of equal length. this implies that one diagonal divides the kite into congruent triangles, and so the angles between the two pairs of equal sides are equal in measure. it also implies that the diagonals are perpendicular.
