Answer:
<u>-10x (1 - y)</u>
Step-by-step explanation:
<u>Given :-</u>
Side 1 = (2x + 5xy)
Side 2 = (-7x - 10xy)
<u>To Find :-</u>
Perimeter
<u>Formula :-</u>
Perimeter (rectangle) = 2 (Side 1 + Side 2)
<u>Solving :-</u>
Perimeter = 2 (2x + 5xy - 7x - 10xy)
= 2 (-5x - 5xy)
= <u>-10x (1 - y) => [Solution]</u>
Note that (-6)^2 = (-6)(-6)
Multiply across. Remember that when multiplying two negative numbers, the product would be a positive answer
(-6) x (-6) = 36
36 is your answer

In this situation you would use cos
which is adjacent over hypotenuse
so I take the cos50 and have it equal to 17 / x
cos(50)= 17/x
which is the same as ...
17 divided by cos(50) =x
x=26.44730506
which rounds to 26.45
So your answer would be A)
I hope everything makes sense, enjoy! <span />
