Answer:

210 yd²

Step-by-step explanation:

If we rotate the shape we get a right angle triangle with a hypotenuse of 29 yd :

The area of a right angle triangle is given by the formula :

A = $\frac{ab}{2}$

Substituting the 2 values given in diagram gives us :

A = $\frac{(20)(21) }{2}$ = 420÷2 = 210

Our units will be yd² as we are dealing with area

name the lengths of the sides of three rectangles with a perimeter of 12 units use only whole numbers

AysviL [449]

The perimeter of a rectangle is 2(w+l)
We can find the lengths by setting the equation equal to 12.
12=2(w+l)
12÷2=(2(w+l))÷2
6=w+l
6=1+5
6=2+4
6=3+3
These are the lengths of the sides of three rectangles with a perimeter of 12 units.
You're probably wondering why the third one has two of the same number, because that's usually how the lengths of sides of squares are, not rectangles.
Well, there's this wonderful thing about the rules of shapes.
<em>Squares ARE rectangles.
</em>Because they follow the rules for a rectangle, squares are also classified as rectangles.
So, the rectangle side lengths are as follows:
1 unit by 5 units
2 units by 4 units
3 units by 3 units

Simplify -3y+2x-5y-7x

Sphinxa [80]

<h3><em><u>Simplify -3y+2x-5y-7x is:</u></em></h3><h3>-8y - 5x</h3>

<em><u>Solution:</u></em>

<em><u>Given that, we have to simplify</u></em>

$-3y + 2x-5y-7x$

We can simplify the above expression by combining the like terms

Like terms are terms that has same variable ( with same exponent) with same or different coefficient

From given,

$-3y + 2x-5y-7x$

Here, like terms are -3y and -5y

And 2x and -7x

Group the like terms

$-3y-5y+2x-7x$

Combine the like terms

$-8y -5x$

Thus the given expression is simplified
