Need help with semester homework is bout to end

To find the correct polynomial, we can use the answers to help us out. The middle variable must be the sum of +2 and another number; the last number in the equation must be the product of +2 and the other number.
Knowing this information, we can use the process of elimination to find the exact polynomial that contains the factor (3x + 2).

A) This can't be it because to get -x as the middle variable, you would need to add -3 and +2. However, -3 x +2 doesn't equal -4.

B) This equation isn't the right one because to get +8 you need to add +6 + 2. However, the product of these two isn't -8.

C) Can't be correct because +2 and -7 = -5, but 2 x -7 = -14...not -9.

D) Is the correct answer because you can add 2 and -1 to get +1. (There is an understood +1 in front of the x in the equation.) The product of 2 and -1 equals -2, which happens to be the last number inside this equation. Therefore, this (D) is the correct answer choice.

Hope I could help you out! If my math is incorrect, or I didn't provide the answer you were looking for, please let me know. However, if the answer was correct and well explained, please consider marking it <em>Brainliest</em>.

Have a good one!
God bless.

Suppose that 16 inches of wire costs 80 cents. At the same rate, how much in cents will 11 inches of wire cost
irga5000 [103]

Find the cost of 1 inch by dividing 80 cents by 16 inches, then multiply that cost by 11:


0.80 / 16 = 0.05 per inch.


11 inches x 0.05 = 0.55


It will cost 55 cents.

James is participating in a 5-mile walk to raise money for a charity. he has received $200 in fixed pledges and raises $20 extra
Firlakuza [10]
The standard formula of a point-slope equation is (y-y1) = m(x-x1). So, we would arrange the final equation in this way as much as possible. Let y be the total amount her receives and x be the number of miles. That would be

y = 200 + 20x
y = 20 (10 + x)

That would be the equation. If he finishes the walk,

y = 20 (10+5)
y = $300

he would receive a total of $300.
