Hello!
First, "the difference" of 2 numbers means you subtract these numbers.
Then, 4 cubed is written as follows:
4³
Subtract:
4³-25
[If necessary] Evaluate:
64-25
39
Hope everything is clear.
Let me know if you have any questions!
Always remember: Knowledge is power!
16(3b−0.25)
=(16)(3b+−0.25)
=(16)(3b)+(16)(−0.25)
=48b−4
To find the area of this entire shape, we must divide it into two rectangles.
The first rectangle is on the bottom of the shape, with a length of 8 cm and a width of 3 cm.
The second rectangle is on the top of the shape. The length is (8-5) cm and the height is (7-3) cm.
To find the area of the total shape, we must add the areas of the two rectangles. To find the area of the rectangle, we use the formula, A = l * w.
8 * 3 = 24 cm^2
3 * 4 = 12 cm^2
24 sq cm + 12 sq cm = 36 square centimeters.
Therefore, the area is 36 square centimeters. Hope this helps! :)
