Isolate the variable by dividing each side by factors that don't contain the variable.
The Answer is B
2d/t^2
Hi there!
The perimeter of any square is the side of the square multiplied by four.
Perimeter= 4 x (5x-2)
Then distribute the four over parentheses.
Perimeter= 4(5x)-4(2)
Perimeter= 20x-8
Hope this helps :)

Answer:
y = 140, x = 159
Step-by-step explanation:
Angle y:
we can find this angle by subtracting 40 from 180, 180-40 = 140 = y
Angle x:
Some measure of an angle plus angle b is equal to 180 degrees: 180-61 = 119
We can now find the measure of the third angle of the triangle: 180-(119+40) = 21
The third angle plus angle x is equal to 180: 180-21 = 159 = x
One easy way to understand it,is to turn the whole number into a fraction
