Answer:306
Step-by-step explanation:
since the width of the bottom square is 10, you split it between the triangles on top. You have to do this because 7 is not the whole width of the two triangles. So then the width of the triangles would be 12, 12 times 9 is 108, you'd have 216 total for both triangles and then the area of the square is 90, 90 plus 216 is 306.
Answer:
$129
Step-by-step explanation:
Amount received last year = $100
Amount received this year = x
x = 29% more of last year
x = $100 + ($100 * 29%)
x = $100 + ($100 * 29 / 100)
x = $100 + $29
x = $129
(3y + 7) + (5y-7)= 8y
(4y - 5)- 8y= -4y-5
