Hi! I'm having trouble with my algebra homework. The second question (b) confused me, I don't understand what they are asking or
Yakvenalex [24]

A

Don't forget that you can also pull out an x besides the 10. The expression should look like this.

A(x) = 10x(x - 5)

The GCF is 10x

B

The area of the Bedroom = 10x ( x - 5)

If the length = 5x then the width is

A/L = 10x (x - 5)/(5x)= 2*(x - 5)

C

Now they are changing the Length to the GCF. We determined in A that the GCF = 10x

This time A/L = 10x(x - 5)/10x = (x - 5)

So the width = x - 5

Can someone help me with this problem ​
Alex_Xolod [135]

Answer:

<h2>A = 20</h2><h2>P = 6√10</h2>

Step-by-step explanation:

The formula of a distance between two points:

d=\sqrt{(x_2-x_1)^2+(y_2-y_1)^2}

A(-3, 0) , B(3, 2)

AB=\sqrt{(3-(-3))^2+(2-0)^2}=\sqrt{6^2+2^2}=\sqrt{36+4}=\sqrt{40}=\sqrt{4\cdot10}=\sqrt4\cdot\sqrt{10}=2\sqrt{10}

A(-3, 0), D(-2, -3)

AD=\sqrt{(-2-(-3))^2+(-3-0)^2}=\sqrt{1^2+(-3)^2}=\sqrt{1+9}=\sqrt{10}

AB = CD and AD = BC

The area of a rectangle:

A=(AB)(AD)

Substitute:

A=(2\sqrt{10})(\sqrt{10})=(2)(10)=20

The perimeter of a rectangle:

P=2(AB+AD)

Substitute:

P=2(2\sqrt{10}+\sqrt{10})=2(3\sqrt{10})=6\sqrt{10}
