Answer:
Step-by-step explanation:
Fist plug in 7 in to the X values like so 12 (3 (7) +5 (7)) then solve in side the parenthesis 3×7 =21 and 5×7=35 then add them 35+21=56 and then you are left with 12(56) or 12×56= 672
I think 0 because 9+11+12=32
32+-32 or 32-32= 0
The distance between two points is found using something called the distance formula. The distance formula goes like this:
(x₂ - x₁) and the y equivalent is the same as the change between the x or y values between each coordinate. Using this formula, the distance between (5,-8) and (53,-28) is ~43.635
