Answer:
C
Step-by-step explanation:
f(x) × g(x)
= 5x(x + 11) = 5x² + 55x, thus
h(x) = 5x² + 55x → C
Step-by-step explanation:
y = -2x² + 4x + 1
Complete the square.
y = -2 (x² − 2x) + 1
y = -2 (x² − 2x + 1) + 1 − (-2)(1)
y = -2 (x − 1)² + 3
The vertex is (1, 3). The leading coefficient is negative, so the vertex is a maximum.

Time = distance / speed
time = 300/194
time = 1.546 hrs...not sure if u need that rounded...if so, then it is 1.5 hrs or 1 1/2 hrs
No it is not the same because you can not reverse division problems the same way you can with multiplication.
5 1/4 / 3 1/2 is asking how many times 3 1/2 can go into 5 1/4. The answer to this would be 1.5
3 1/2 / 5 1/4 is asking how many times 5 1/4 can go into 3 1/2. The answer to this would be .667
4. Option 3, a has length of infinity and mn does not split a, a splits mn
5. Option 2, only 1 possibility, since it has to split mn into equal parts
