What are some other ways the answer can be determined ( other than Multiplication) Will mark and 5 STARS, THANKS

-2

7 - 9 = -2

reversed:

-2 + 9 = 7

you can first factor out the n to get n(1+5). we know that 1+5 is 6, so we just have 6n.

won't that be plagrisim thought?

step-by-step explanation:

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
