I need help with this question!!!

USPshnik [31]

Answer: 5x - 2

Step-by-step explanation:

So area is length*width, we have the area and length which is 5x^2 + 43x - 18 and x + 9. So we need to divide. First the x, what times x is 5x^2? 5x, x*x is x squared. Then we need to apply the 5x to 9. 5x*9 is 45x, and we can’t do anything to the 18 because 18/5 is a decimal. After that we subtract the new area with the old one. 5x^2 + 43x - 18 minus 5x^2 + 45x which is -2x - 18. Now we divide the -18 with 9 which is -2. Remember the 5x we had from using the x? We put that and -2 together which is 5x-2, and that’s your width. Hope this helped!

What is the slope of the line that is perpendicular to the given line x-2y=10?

laiz [17]

Not sure how to do it in this form but in slope intercept form for example if the slope was -4/3 the perpendicular would be 3/4 it’s the negative reciprocal of the answer

Eduardo bought 2-liter sports drink for soccer practice.During practice,Eduardo drank 250 millimeters of the sports drink.Then h

adelina 88 [10]

Answer:

1,250 millileters

Step-by-step explanation:

The computation of the number of milliters of the sports drink left is shown below:

Given that

The 2-liter sports drink is purchased

And, drank 250 millimeters and than drank one-half liter of the drink

Now convert liter to millileter

1 litre = 1000 milliliter.

2 liters = 2 × 1000 milliliters.

= 2000 milliliters.

Now the left drink would be

= (2000 - 250) - (250 × 2)

= 1,750 - 500

= 1,250 millileters

1.075(5.25)x - 5.25(0.25)(x-3)

Vitek1552 [10]

For this case we must simplify the following expression:

$1,075 (5.25) x-5.25 (0.25) (x-3) =$

So, solving the first parentheses we have:

$5.64375x-1.3125 (x-3) =$

We have to:

$- * + = -\\- * - = +\\5.64375x-1.3125x + 1.3125 (3) =\\5.64375x-1.3125x + 3.9375 =$

We add similar terms taking into account that different signs are subtracted and the sign of the major is placed:

$4.33125x + 3.9375$

Finally, the simplified expression is: $4.33125x + 3.9375$

ANswer:

$4.33125x + 3.9375$
