0.5h(115 + 85) = 6550
0.5h(200) = 6550
100h = 6550
h = 655 cms
height is 655 cms
Answer:
2x(2x²+x+1)
Dtep-by-step explanation:
f(x) = 9x³+2x²-5x+4
g(x) = 5x³-7x+4
f(x) - g(x)
= 9x³+2x²-5x+4 - (5x³-7x+4)
= 9x³+2x²-5x+4-5x³+7x-5
= 4x³+2x²+2x
= 2x(2x²+x+1)
Whole package weighs 20pounds
1.65 = 5pounds
0.12 = extra pound
3.45 - 1.65 = 1.80 : 0.12 = 15pounds
Adding up 15pounds and the first 5 pounds equal 20 pounds
Add 6 to left middle and right
then, divide them all by 3
2h/15=20 so the answer to h would be h=150
