240 inch^2 may should be #5 being that Length x width = A.
So 12 x 20... I hope cause I mean I shoot haven't seen a question like this in ages. But for a rectangle A = LW and for triangles A= 1/2 base x height.

Solve for x. Round your answer to the nearest hundredth.
Zarrin [17]

Answer:

Option B is correct

Step-by-step explanation:

2x² - 6x + 3 = 0

Using Quadratic formula:

x = \frac{-b+-\sqrt{b^{2}-4ac}}{2a}

a = 2, b = -6, c = 3

x = \frac-(-6)+-{\sqrt{(-6)^{2}-4(2)(3)}}{2(2)}

x = \frac{-(-6)+-\sqrt{(-6)^{2}-4(2)(3)}}{2(2)}\\

=\frac{6+-\sqrt{36-24}}{4}\\\\=\frac{6+-\sqrt{12}}{4}\\\\=\frac{6+-3.46}{4}\\\\

=\frac{6+3.46}{4}

x = 2.37  


=\frac{6-3.46}{4}

 x = 0.63

How to solve (x-10)(x + 10)
alexandr402 [8]

Answer:

x² - 100

Step-by-step explanation:

Use the FOIL method. The FOIL method is the way in which you multiply the terms:

FOIL stands for First, Outside, Inside, Last. Multiply:

First:

x * x = x²

Outside:

x * 10 = 10x

Inside:

-10 * x = -10x

Last:

-10 * 10 = -100

Combine like terms:

x² + 10x - 10x - 100

x² + (10x - 10x) - 100

x² - 100

x² - 100 is your answer.
