Answer:
x^2+29x+210
I hope this helps! I did this through the FOIL method. :)
trapezoid = 1/2 (a+b) h
= 1/2(38+28) 15
= 1/2 × 66 × 15
= 33 × 15
= 495 square feet.
x=4, y=3 (4,3)
Step-by-step explanation:
- x=7−y
19+y=22
y=3
-Substitute y=3y=3 into x=7-yx=7−y.
x=4
I think it is 145 degrees because 180- 35= 145
