I need help on number 3
MatroZZZ [7]
The first step is to turn the 3 1/5 into an improper fraction, and then change it so that the denominator is 10, just like the 4/10, I'm order to make it easier to divide. then you divide 32 by 4 to get 8.

The polynomial 8x2 – 8x + 2 – 5 + x is simplified to 8x2 – gx – h. What are the value of g and h?
igor_vitrenko [27]

Answer:

Option D: g = 7 and h = 3

Step-by-step explanation:

The polynomial is;

8x² – 8x + 2 – 5 + x

Simplifying this gives;

8x² - 7x - 3

If this is simplified to 8x² – gx – h

Thus, by comparison of terms;

– gx = - 7x

-x will cancel out to get;

g = 7

Similarly, - h = - 3

Thus,h = 3

Therefore; g = 7 and h = 3

HELP ASAP!!! A man is 6 feet 2 inches tall. To find the height of a tree, the shadow of the man and the shadow of the tree were
Whitepunk [10]

1 ft = 12 inches

6 ft = 72 inches (multiply both sides by 6)

6 ft + 2 inches = 72+2 = 74 inches

6 ft, 2 inches = 74 inches

--------------------

1 ft = 12 inches

2 ft = 24 inches

2 ft + 1 in = 24+1 = 25 inches

2 ft, 1 in = 25 inches

--------------------

1 ft = 12 inches

3 ft = 36 inches

3 ft + 7 in = 36+7 = 43 inches

3 ft, 7 in = 43 inches

--------------------

To rewrite the problem a bit in equivalent form, we have a man who is 74 inches cast a shadow that is 25 inches long. The tree has a shadow of 43 inches. We want to find the height of the tree, which for now we'll call x

(tree height)/(tree shadow) = (person height)/(person shadow)

x/43 = 74/25

25x = 43*74

25x = 3182

x = 3182/25

x = 127.28 inches

The tree is 127.28 inches tall which is the same as 10 ft, 7.28 inches

because 127/12 = 10 remainder 7, then we add on the 0.28 portion
