If the length of a rectangle is x-2 and its area is 2x3 – 8x2 + 2x+12, it’s width would be what?

Width would have to be a quadratic
Use long division to find the other factor of the cubic polynomial P (x).
P (x) factors in case it is reducible over R[x]
if it weren't then P (x) mod R [x] would be a field
otherwise you could use the Eisenstein Criterion.

Lou's car had 6.6 gallons in the 16- gallon tank on the coldest day of the year . Lou filled the tank with gas that cost 3.70 pe

Ronch [10]

Answer: $33.48

Step-by-step explanation:

Given that:

Capacity of car tank =. 16 gallons

Gallons of already filled = 6.6 gallons

Amount left of tank capacity = 16 - 6.7

Amount left of tank capacity = 9.3 gallons

Cost of gas per gallon = $3.60

Hence, amount spent in gas will be

Amount left of tank capacity * cost per gallon of gas

= 9.3 gallons * $3.60

= $33.48

Total amount spent on gas = $33.48

Please help find the value of x and show me steps so I can try to learn it!!

Answer:

$x = 30$

Step-by-step explanation:

If we take a look at the given picture, we can see that both sides are almost completely identical, so they must almost have the same value.

Let us do the plug in. Keep in mind that the angle is obtuse, meaning over 90 degrees, and angle identical or lower than 90 is incorrect.

$x=18$

$(x + 90)°$

$(18 + 90) = 108$

True.

$4x$

$4(18) = 72$

False. Meaning the 18 would not work.

x = 22.5

$(22.5 + 90) = 112.5$

True.

$4(22.5) = 90$

False. Meaning that 22.5 does not work.

x = 30

$(30+90) = 120$

True.

$4(30) = 120$

True. Meaning that 30 is the answer and can work.

x = 54

$(54+90) = 144$

True.

$4(54) = 216$

False. Although the angle is larger than 90, 180 is a straight line, and we can see that the angles given are not straight lines or greater.

Answer:

Step-by-step explanation:

You cross multiply. So it's 14 times 250 divided by 115.

That's how much you would add to the 250 mixture.

14 times 250 is 3500, Divided by 150= 23 and a third.

It does say round to the nearest gram.

So we had to add about 23 g to 250 g of flour.
