Answer:
28
Step-by-step explanation:
x-10+2=20
add -10 and 2 together to simplify the equation
x-8=20
add 8 to both sides to isolate x
x=28
hope this helped!
Answer:
B - x=5
Step-by-step explanation:
If y=25 is 250% more than y=10, so multiply 2 by 250% and you get 5
38, I think I don't know if i am correct but a cube has 6 sides and if you roll it twice 6*6=36 and a coin has 2 sides and is tossed once so 2*1=2 so 2+36+38. I am sorry if its isn't correct.
Let the side length of the original square be x, then
1/4 x^2 = (x - 3)^2
x^2 = 4(x^2 - 6x + 9) = 4x^2 - 24x + 36
3x^2 - 24x + 36 = 0
3(x^2 - 8x + 12) = 0
x^2 - 8x + 12 = 0
x^2 - 2x - 6x + 12 = 0
x(x - 2) - 6(x - 2) = 0
(x - 6)(x - 2) = 0
x - 6 = 0 or x - 2 = 0
x = 6 or x = 2
therefore, the side length of the original square is 6 inches.
Hope this helps!
