f(x)g(x) = 9x² + 10x - 16
<u>Step-by-step explanation:</u>
Step 1:
Given f(x) = 3x - 4 × 2 + 6x and g(x) = 5x + 2 × 2 - 3x
f(x) = 9x - 8
g(x) = 2x + 4
f(x)g(x) = (9x - 8)(2x + 4)
= 18x² + 36x - 16x -32
= 18x² + 20x - 32
= 9x² + 10x - 16
Answer:
Average change in temperature is - 2.8 Fahrenheit per hour.
Step-by-step explanation:
Average change in temperature is the change in temperature divided by the time taken for the change.
Change in temperature = (-11.2) F- 0 F
= -11.2 F
Time taken for the change in temperature = 10 pm - 6 pm
= 4 hours
Average change in temperature = Change in temperature / time taken for the change
= 
= - 2.8 Fahrenheit per hour
Answer:
Step-by-step explanation:
Answer:
depends on how you understand math.
Let x be the number of households with TV.
So .68x would be the number of households with cable.
If 8000 were added to the above number, it would be equal to 67,600,000.
Thus we have our equation:
.68x + 8000 = 67600000
Solving for x:
.68x = 67592000
x = 99,400,000
