I don't know what the answer to number 1 is.

2. <u>Center</u>
25x² + 4y² - 50x - 24y - 39 = 0
           25x² + 4y² - 50x - 24y = 39
           25x² - 50x + 4y² - 24y = 39
            25(x² - 2x) + 4(y² - 6y) = 39
25(x² - 2x + 4) + 4(y² - 6y + 9) = 39 + 25(4) + 4(9)
25(x² - 2x + 4) + 4(y² - 6y + 9) = 39 + 100 + 36
25(x² - 2x + 4) + 4(y² - 6y + 9) = 175
                <u>25(x - 2)²</u> + <u>4(y - 3)²</u> = <u>175</u>
                    175           175        175
                    <u>(x - 2)²</u> + <u>4(y - 3)²</u> = 1

Explain how to use the least common multiple to find 5/9 - 2/15
polet [3.4K]
Because you need to have the same denominators to subtract fractions, you need to find the LCM of 15 and 9. The LCM of 15 and 9 is 45. Because 15 goes into 45 3 times, you multiply 2* 3 to find the numerator. Because 9 goes into 45 5 times, you multiply 5*5 to find the numerator. The new equation is 25/45 - 6/45. The answer is 19/45, which cannot be simplified any further.

Write a ratio in simplified form of the area of the shaded figure to the area of the figure that encloses it.
Zarrin [17]
<em>First, let's start by finding the Areas for both shaded and not shaded.</em>

-Area of the shaded area 
= Length²
Area of the shaded area = 6² = 36
-Area of the not shaded region = \frac{LH}{2} 
Area of the not shaded region = \frac{5*6}{2}
                                                    = \frac{30}{2}
                                                    = 15
<em>Now, Let's make our ration!
</em>
Area of shaded : Area of not shaded
           36            :               15
           <u>12             :                5</u>
