You would turn the -9 into a 9 and multiple 9x9x9x9 so 81 x81 is 6,561 hope it helps

If I have 60 coins consisting of dimes and quarters and I have x dimes give an expression that would represent the number of qua

Nikolay [14]

Hey there!

Here is an exspression that would help recognize the amount of quarters you have:

X = Dimes

K = Quarters

X + K = 60 coins

Hope this helps!

Write 3-5 sentences about the process of the Difference of squares Factoring Method

lisabon 2012 [21]

To factor a difference of squares, the following steps are undertaken: Check if the terms have the greatest common factor (GCF) and factor it out. Remember to include the GCF in your final answer. Determine the numbers that will produce the same results and apply the formula: a2– b2 = (a + b) (a – b) or (a – b) (a + b)

The area of the trapezoid will be 32.5 square feet. Then the volume of the geometry will be 341.25 cubic feet.

<h3>What is Geometry?</h3>

It deals with the size of geometry, region, and density of the different forms both 2D and 3D.

The figure is shown.

Then the volume of the given geometry will be

Volume = Area of the trapezoid × Height

Then the area of the trapezoid will be

$\rm Trapezoid \ area = \dfrac{1}{2} \times (8 + 5) \times 5\\\\\\Trapezoid \ area = 32.5 \ ft^2$

Then the volume of the geometry will be

Volume = 32.5 × 10.5

Volume = 341.25 cubic ft.

More about the geometry link is given below.

Will mark brainliest answer , pls answer !!!

Answer:

$x^{2} +8x+12$

Step-by-step explanation:

So basically the equation is (x+2) times (x+6). Use the FOIL method to multiply across like this:

x*x + x*6 + 2*x + 2*6

$x^{2} +6x+2x+12$

Combine like terms

x^2 + 8x + 12

Thank me later :)
