7•4 =28, -5•0 =0... 28+0=28
The answer is 18
If you subtract 47-29=18
Then if you subtract 47-65=18 the pattern is to add 18
Volume of a pyramid is 1/3 base x height or 1/3 b h ( rest are in the Comments
The equation that is equivalent is -2+(-7).
Answer:
The area of the green polygon is 81.
The area of the yellow polygon is 3.
Step-by-step explanation:
To get the green polygon, simply multiply 9 by 9. (The sides)
To get the yellow polygon, first you have to find the height. We know that the side of the green polygon is 9, so you have to do 9-7 to find the height of the triangle. That is 2
Then to find the area, use the equation:
. The h would be 2 and b would be 3.
The answer is 3.
