Answer:
A =315 cm^2
Step-by-step explanation:
The area of a trapezoid is found by 
A = 1/2 (b1+b2) *h
where b1 and b2 are the lengths of the bases and h is the height
A = 1/2 ( 13+29) *15
A  = 1/2 (42)* 15
A =315 cm^2

Answer:
62 and 63
Step-by-step explanation:
125/2= 62.5 (Middle integer or mean of the 2 integers)
That means that the integers are 62 and 63
 
        
             
        
        
        
Your answer would be the last option, (6x² - 5)(x² + 2).
This is because when you expand it, you get:
6x² × x² = 6x⁴
6x² × 2 = 12x²
-5 × x² = -5x²
-5 × 2 = -10
Which are all the correct terms.
I hope this helps!
