8 0

We can use FOIL to solve.

(x + 7)(x + 10)

(x * x) + (x * 7) + (7 * x) + (7 * 10)

x² + 7x + 7x + 70

x² + 14x + 70

Best of Luck!

Find the greatest common factor of the monomials.<br><br> 20x², 36x =
Goshia [24]

Answer:

i think its -4

Step-by-step explanation:

Simplifying

-20x2 = 36x

Solving

-20x2 = 36x

Solving for variable 'x'.

Reorder the terms:

-36x + -20x2 = 36x + -36x

Combine like terms: 36x + -36x = 0

-36x + -20x2 = 0

Factor out the Greatest Common Factor (GCF), '-4x'.

-4x(9 + 5x) = 0

-4.

A Norman window is a window with a semi-circle on top of regular rectangular window. What should be the dimensions of the window
victus00 [196]

Answer:

Side lengths = 1.68 ft and width = 3.36 ft.

Step-by-step explanation:

Let the side lengths of the window be L and the width = 2r ( r is also the radius of the semi-circle).

So we have

Perimeter = 2L + 2r + πr = 12

Area = 2rL + 0.5πr^2

From the first equation

2L = 12 - 2r - πr

Substitute for 2L in the equation for the area:

A = r(12 - 2r -  πr) + 0.5πr^2

A = 12r - 2r^2 -  πr^2 + 0.5πr^2

A =  12r - 2r^2 - 0.5πr^2

We need to find  r for the maximum area:

Finding the derivative and equating to zero:

A' = 12 - 4r -  πr = 0=

4r + πr = 12

r = 12 / ( 4 +  π)

r = 1.68 ft.

So the  width of the window = 2 * 1.68 = 3.36 ft.

Now  2L = 12 - 2r - πr

=  12 - 2*1.68 - 1.68π

= 3.36

L = 1.68.

The data points of a person with two different factors are related in a scatterplot. The term "correlation" refers to this connection.

A correlation is the relationship between any two variables represented on any graph.

The correlation is divided into three main categories based on the sort of relationship between the variables. Those are

i) Positively correlation

ii) Negative correlation

iii) No correlation
