Answer[:]
B) 4x + 6 = 38

We need to substitute 8 for X.
4*8+6=38
4*8=32
32+6=38

Tip[:]
-When it gives you what X is (A specific number) go to each equation and substitute that number for X and see if the answer makes sense. Best of luck!

You can see that if you plug 8 in for x in equation "B" you will get a true statement, and therefore Choice B is your answer:

4(8) + 6 = 38
32 + 6 = 38
38 = 38 Check it out!

The area of a rectangle is x2 - 2x - 15 and the length of the rectangle is x + 3. Find the width of the rectangle.

Vesnalui [34]

Area of the rectangle= L* w
$x^{2} -2x-15$
On expanding;
$x^{2} -5x+3x-15$
=x(x-5)+3(x-5)
=(x+3)(x-5)
The width is (x-5)

What is the correct answer for this problem?Explain

To solve this you would make a triangle, Assuming you had a piece of paper.

It would look like the picture included (where ever that is) sorry for the horrible drawing with mouse.

You can then you Pythagorean Theorem to solve this

$a^{2} + b^2 =c^2$

width will be (a)

put in your variables

$a^2 + 72^2 = 90^2$
$a^2 + 5184 = 8100$

Subtract 5184 over and get
$a^2 = 2916$

square root both sides and get
a=54

the field is 54 meters wide
