Which expression is NOT equivalent to 4x + 12y? 16(x + y)
2(2x + 6y)
(2x + 6y) + (2x + 6y)
4(x + 3y)

16(x+y)

Step-by-step explanation:

16 times x + 16 times y= 16x+16y

2(2x+6y)=4x+12y

(2x+6y)+(2x+6y)=4x+12y

4(x+3y)=4x+12y

Hence, 16(x+y) is not equivalent to 4x+12y.

the answer is 8/21

hope this

11.2

step-by-step explanation:

when doing tangent the tangent of the angle is equal to the opposite side from the angle over the adjacent side to the angle.

tan43 = x / 12

move 12 over by multiplying each side by 12

12tan43 = x

x = about 11.2
