Given a rectangle with side lengths of and , what is its area?
maw [93]
B = 2x+4
H = 3x-5

A = bh
   = (2x+4)(3x-5)
   = (2x)(3x)+(2x)(-5)+(4)(3x)+(4)(-5)
   = 6x^2 - 10x + 12x - 20
   = 6x^2 + 2x - 20

So the answer is A (6x^2 + 2x - 20) (i think)

Answer:

So the final answer is

-8\sqrt{3}

Step-by-step explanation:

Radicals:

In mathematics, a radical expression is defined as any expression containing a radical (√) symbol. Many people mistakenly call this a 'square root' symbol, and many times it is used to determine the square root of a number. However, it can also be used to describe a cube root, a fourth root, or higher.

The given expression is

-5\sqrt{3} -3\sqrt{3}

Now take common radical out so we will get

\sqrt{3}(-5-3)

Now add the Parenthesis part.

\sqrt{3}(-8)

So the final answer is

-8\sqrt{3}
