B. Because 20 is greter than 18.
Answer:
Area of trapeze= (B+b):2×h
Therefore : (7+10):2×4=34
Good luck!
The solution to the quadratic equation are option C) x= -5 and option E) x=3.
<u>Step-by-step explanation</u>:
The given quadratic equation is x²+2x-15 = 0.
Using the factorization method,
- product of the roots should be -15.
- Sum of the roots should be 2.
⇒ -15 = 5
-3
⇒ 2 = 5+(-3)
(x+5)(x-3) = 0
Therefore, x = -5 and x = 3
If the diameter of the cylinder's base is 10, then the radius is half that, or 5.
