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>

C= 1 because 1+2= 3 3x3 = 9 so c equals 1
6(G+9)
you have to use the distributive property.
6*G=6G
6*9=54
answer is 6G+54
Answer:
x = 12
Step-by-step explanation:
We know that the total angle measure of a triangle is 180 degrees, so the sum of all the angles should be 180 degrees.
Therefore, we can add all the angles, set them equal to 180 and solve for x
2x+5 + 6x-5 + 7x = 180
We can combine all the x terms and all the numerical terms on the left side of the equation to get:
(2x+6x+7x) + (5-5) = 180
15x = 180
Then we can divide both sides by 15 to isiolate x
15x = 180
x = 180/15 = 12
