What is the area of a parallelogram with a base of 13.5 in. and a height of 12.2 in.?
yulyashka [42]
<h3>Answer: 164.7 square inches</h3>

============================================

Explanation:

The area of a parallelogram is equal to the base times height

area = base*height

area = 13.5*12.2

area = 164.7

This is pretty much identical to a rectangle's area formula. This is because a rectangle is a special type of parallelogram (one with all four angles at 90 degrees).

How to use standard form
Lena [83]

Answer: Standard form is another way to write slope-intercept form (as opposed to y=mx+b). It is written as Ax+By=C. You can also change slope-intercept form to standard form like this: Y=-3/2x+3. Next, you isolate the y-intercept(in this case it is 3) like this: Add 3/2x to each side of the equation to get this: 3/2x+y=3.

Step-by-step explanation: hope this helps

Does anyone know how to solve this?

Sin is -sqroot3/2, cosine is 1/2, when ever you are given a point, the y value is always sin and x value is always cosine.

Simplify the radical expression.. square root of 128
Vaselesa [24]
Hello,

first we have to descompose the number:

128  | 2
  64  | 2
  32  | 2
  16  | 2
    8  | 2
    4  | 2
    2  | 2
    1

So: 
128= 2x2x2x2x2x2x2 \\ 128=2^{6} *2

Therefore:
\sqrt{128}= \sqrt{2^{6} *2}

You must know these properties:

\sqrt{a*b} = \sqrt{a} * \sqrt{b}\\ \\ \sqrt[b]{x^a}= x^{ \frac{a}{b}}

then:

\sqrt{2^{6} *2} \\ =\sqrt{2^{6}}*\sqrt{2} \\ =2^{ \frac{6}{2}}*\sqrt{2} \\ =2^3*\sqrt{2} \\ \boxed{=8*\sqrt{2}}
