Answer:

\frac{(x +  \frac{3y}{5})^{2} }{9}

Step By Step Explanations:

<em>1) Simplify 1/9x² to x²/9.</em>

<em>\frac{ {x}^{2} }{9}  +  \frac{2}{15} xy +  \frac{1}{25}  {y}^{2}</em>

<em>2</em><em>)</em><em> </em><em>Simplify</em><em> </em><em>2</em><em>/</em><em>15xy</em><em> </em><em>to</em><em> </em><em>y</em><em>²</em><em>/</em><em>25</em><em>.</em>

<em>\frac{ {x}^{2} }{9}  +  \frac{2xy}{15}  +  \frac{1}{25}  {y}^{2}</em>

<em>3</em><em>)</em><em> </em><em>Simplify</em><em> </em><em>1</em><em>/</em><em>25y</em><em>²</em><em> </em><em>to</em><em> </em><em>y</em><em>²</em><em>/</em><em>25</em><em>.</em>

<em>\frac{ {x}^{2} }{9}  +  \frac{2xy}{15}  +  \frac{ {y}^{2} }{25}</em>

<em>4</em><em>)</em><em> </em><em>Factor</em><em> </em><em>with</em><em> </em><em>quadratic</em><em> </em><em>formula</em><em>.</em>

<em>\frac{1}{9} (x +  \frac{3y}{5})(x +  \frac{3y}{5} )</em>

<em>5</em><em>)</em><em> </em><em>use</em><em> </em><em>product</em><em> </em><em>rule</em><em>.</em>

<em>\frac{(x +  \frac{3y}{5} )^{2} }{9}</em>

<em><u>Therefor</u></em><em><u>,</u></em><em><u> </u></em><em><u>the</u></em><em><u> </u></em><em><u>answer</u></em><em><u> </u></em><em><u>is</u></em><em><u> </u></em><em><u>(</u></em><em><u>x</u></em><em><u> </u></em><em><u>+</u></em><em><u> </u></em><em><u>3y</u></em><em><u>/</u></em><em><u>5</u></em><em><u>)</u></em><em><u>²</u></em><em><u>/</u></em><em><u>9</u></em><em><u>.</u></em>

Find the are of the trapizoind
Andreyy89

9514 1404 393

Answer:

  7.5 square units

Step-by-step explanation:

The formula for the area of a trapezoid is ...

  A = 1/2(b1 +b2)h

where b1 and b2 are the lengths of the parallel bases, and h is the perpendicular distance between them.

Here, the bases are TR = 1 and PA = 4. The height is 3 units, so the area is ...

  A = (1/2)(1 +4)(3) = 15/2 = 7.5 . . . . square units

QUESTION 8. An unknown number is added to 8. The sum is
Rudik [331]

Answer:

82

Step-by-step explanation:

Let the unknown number be x

If an unknown number is added to 8, this is expressed as;

8 + x

<em>If The sum is  then divided by 9 to give the answer 10, then;</em>

<em>(8+x)/9 = 10</em>

<em>Cross multiply</em>

<em>8 + x = 9 * 10</em>

<em>8 + x = 90</em>

<em>x = 90 - 8</em>

<em>x = 82</em>

Hence the unknown number is 82
