Answer:
4 inches
Step-by-step explanation:
We just have to find the cube root of 64 :)
For example if we had 8 cubes of 1 inch, you can put them together into a cube of 2 inches,
8 is the cube of 2 = 2 x 2 x2
Do you get it?
Same goes for 27 cubes of 1 inch, you get a cube of 3 inches
So for 64 cubes, we find the cube root and we get 4
It's 15/7
Top one is 56
-9 + <u>112 </u>= 7(x2 - 8x + <u>16 </u>)
i= -6
-5i-15=15
if we use inverse operation here, it would be -5i=30, so i= -6
