Answer:
true
Step-by-step explanation:
5x + 4x = 9x
3y + 7y = 10y
8 + 34 = 42
False
5x+3y=8
4x+7y=34
Then:
5x+4x+3y+7y=9x+10y
9x+10y=43 not 9x-10y
(3r+8)(4+1)
slope = = - → A
The slope is negative as the ramp slopes down from left to right
Since the trapezoid can be inscribed in a circle, that means angle B + angle D = 180 degree. Since AB is parallel to CD, then angle B + angle C = 180 degree. Therefore, angle D = angle C.
