Answer:
12 cm
Step-by-step explanation:
The area (A) of a trapezium is calculated as
A = 
h (a + b)
where h is the perpendicular height and a, b the parallel bases.
Here A = 45, h = 5, a = 6 and b = ?, thus
45 = × 5 × (6 + b) = 2.5(6 + b) = 15 + 2.5b ( subtract 15 from both sides )
30 = 2.5b ( divide both sides by 2.5 )
b = 12
The measure of the other parallel side is 12 cm
Answer:
Below.
Step-by-step explanation:
Yes, because if x = 1:
y = 1^3 + 1^2 - 2 + 1
= 2 - 2 + 1
= 1 which is a cubic number.

Step-by-step explanation:
Answer: -14
<u>Step-by-step explanation:</u>
f(x) = x - 3 --> x - 3
- g(x) = -(x + 11) --> <u>-x - 11 </u>
0x - 14 --> -14
NOTE: Your answer choices do not match up unless you are multiplying.
f(x) * g(x)
(x - 3)(x + 11)
= x(x + 11) - 3(x + 11)
= x² + 11x - 3x - 33
= x² + 8x - 33 (Option D)
