……….Yes it is true that trapezoid is a polygon that has two bases
Answer:
x=-5
Step-by-step explanation
The first box has eight x's and six 1's which means that it would be written as 8x+6
The second box has four x's and fourteen -1's which means that it would be written as 4x-14
You set them equal to one another
8x+6=4x-14
You subtract 4x from both sides
4x+6=-14
Subtract 6 on both sides
4x=-20
Divide 4 on both sides
x=-5

Answer:
14.7cm^3
Step-by-step explanation:
The volume formula for a pyramid is l·w·h/3 or BH/3
The base of the height is 6.9 and the height is 6.4
(6.9)(6.4)=44.16
44.16/3=14.72
14.72 rounded to the nearest tenth is 14.7cm^3

Step-by-step explanation:
Judging from the high of 400, her day 21 appears to be approx 300
if she put in 100 then the next five days she added a total of 200 more to reach 300
200/5 = $40 / day
