The total area painted was 480 inches. 4 cubed is 64, 8 cubed 512. 512 +64= 576. Then you subtract two sides of the 4 inch square because the bottom is not painted and one side is pushed against the 8 inch cube. That means 576-32= 544. Then you subtract the bottom of the 8 inch cube, which means 544-64= 480.
Answer:
12x^2-7x-10
Step-by-step explanation:
I did binomial into binomial method
3x(4x-5)+2(4x-5)
12x^2-15x+8x-10
12x^2+(-15+8)x-10
12x^2-7x-10
Is this qusioun as of today may 18?
2x+4y=12
y=x-3
Since we know what y equals, we can plug this into the first equation:
2x+4(x-3)=12
We can then distribute:
2x+4x-12=12
And solve for x:
6x-12=12
6x=24
x=4
We can then plug x into the second equation and find y:
y=x-3
y=4-3
y=1
Therefore x=4 and y=1
