If a rectangle is (x+2) wide and (x-7) in length, the area of the rectangle is?

Answers

Answer: x² - 5x - 14

Step-by-step explanation: Start with the formula for the area of a rectangle.

Area = length x width

To multiply these two binomials, let's use the F.O.I.L. method.

The product of the first terms is x².

The product of the outer terms is -7x.

The product of the inner terms is 2x.

The product of the last terms is -14.

So we have x² - 7x + 2x - 14 which simplifies to x² - 5x - 14.

h-(-2.22)=-7.851 solve for h

Answers

Answer:

[tex]\boxed {h = -10.071}[/tex]

Step-by-step explanation:

Solve for the value of [tex]h[/tex]:

[tex]h - (-2.22) = -7.851[/tex]

The opposite of [tex]-2.22[/tex] would be [tex]2.22[/tex]:

[tex]h - (-2.22) = -7.851[/tex]

[tex]h + 2.22 = -7.851[/tex]

-Subtract both side by [tex]2.22[/tex]:

[tex]h + 2.22 - 2.22 = -7.851 - 2.22[/tex]

[tex]\boxed {h = -10.071}[/tex]

So, the value of [tex]h[/tex] is [tex]-10.071[/tex].

How can I split 166 in half

Answers

You divide 166 by 2. The answer would be 83.

The value of splitting 166 in half gives two equal halves of 83 each.

When 'split' a number in half, dividing the number into two equal parts.

Here want to split the number 166 in half.

Perform a division operation by dividing 166 by 2.

Division is the opposite operation of multiplication.

When divide a number by 2, you are essentially finding the value of half of that number.

So, the calculation is as follows:

166 ÷ 2 = 83

This means that half of 166 is 83.

Divide the number 166 into two equal parts, each being 83.

If add both halves together, you get the original number back:

83 + 83 = 166

Therefore, dividing 166 by 2 allows to splitting it equally into two halves, each having a value of 83.
