Answer:
80 marbles
Step-by-step explanation:
8 times 2=16
40 times 2=80
Assuming that the numbers after the variables are exponents: 2(-4)^2 - 2(2)^4 + (3)^2 - (-4)^2 + (2)^4 would be equivalent to
32 - 32 + 9 - 16 + 16
The 32's cancel out and so do the 16's, leaving you with:
9
A triangle is equal to 180. Using that, we can make a equation.
6x-3 + 3x+6 + 5x = 180
Combining the like terms, we get:
14x+3 = 180
Subtract 3 on both sides.
14x = 177
Finally, divide 177 by 14.
x = 177/14 or about 12.6
