Rectangle ABCD has vertices A(-3,7), B(5,7) and C(5,-1). Find the coordinates of D

x = 2

step-by-step explanation:

if sr parallel to ba then the sides bc and ac are in proportion, that is

= ← substitute values

= ( cross- multiply )

27x = 6(4x + 1)

27x = 24x + 6 ( subtract 24x from both sides )

3x = 6 ( divide both sides by 3 )

x = 2

40 i don’t know lololol

first the equation needs to be simplified. so the equation would now look like:   52-24+11

then you multiply.

and when you multiply, you will get the answer of 39.  

this would be 35. 35 + 5 = 40. you take the known constant and subtract by the answer of the equation and you get y.
