Answer:
area is 56
Step-by-step explanation:
Answer:
47
Step-by-step explanation:
251+31= 282
282 divided by six = 47
5x^2 - (2x - 3)^2 =
5x^2 - ((2x - 3)(2x - 3)) =
5x^2 - (4x^2 - 6x - 6x + 9) =
5x^2 - (4x^2 - 12x + 9) =
5x^2 - 4x^2 + 12x - 9 =
x^2 + 12x - 9 <===
Let, the number = x
It would be: x * 0.135 = 57
x = 57 / 0.135
x = 422.23
Hope this helps!
3x : 2 = 15
3x = 15 * 2
3x = 30
x = 30 : 3
x = 10
--------------------------------
3(10) :2 = 15
