Answer:
-2[h(3)] = 0
Step-by-step explanation:
Step 1: Define
h(x) = 2x - 6
Step 2: Find h(3)
h(3) = 2(3) - 6
h(3) = 6 - 6
h(3) = 0
Step 3: Find -2[h(3)]
-2(0)
0
3x2 + 11x – 4 = (3x - 1) (x + 4)
answer is B. <span>(3x – 1) and (x + 4) ( second choice)</span>
<span>Found a similar problem with the given table.
Elapsed time
(Minutes) 0 10 20 30 40 50 60 70 80 90
Rate
(gallons / minute) 42 40 38 35 35 32 28 20 19 10
Because the interval is every 10 minutes, we will use 10 and multiply it to each rate and get the sum total.
42*10 + 40*10 + 38*10 + 35*10 + 35*10 + 32*10 + 28*10 + 20*10 + 19*10 + 10*10
420 + 400 + 380 + 350 + 350 + 320 + 280 + 200 + 190 + 100
2,990
There will be a total of 2,990 gallons in the tank after 90 minutes. </span>
