2x² - 5xy - y³


x = -3 and y = -2

2.(-3)² - 5.(-3).(-2) - (-2)³

2.9 + 15.(-2) - (-8)

18 - 30 + 8

The perimeter of the triangle is 40 units.Which of the following equations could be used to find the value of x?
Artyom0805 [142]

Answer:

13x + 112 = 320.

Step-by-step explanation:

The perimeter is the sum of the 3 sides:

1/2 x + 3/8 x + 11 + 3/4 x + 3 = 40

1/2 x + 3/8 x  + 3/4 x + 3 + 11 = 40

1/2 x + 3/8 x  + 3/4 x + 14 = 40

Multiply through by 8 to remove the fractions:

4x + 3x + 6x  + 14 = 40

13x + 112 = 320.

The results of joes survey show that baseball is the favorite sport for 18 out of 25 people. What percent do not like sports?
charle [14.2K]

well if 18 out of 25 like it, then the remaining 7 doesn't like it, namely 7 out of 25.

if we take 25 to be the 100%, what is 7 off of if in percentage?

\bf \begin{array}{ccll} amount&\%\\ \cline{1-2} 25&100\\ 7&x \end{array}\implies \cfrac{25}{7}=\cfrac{100}{x}\implies 25x=700\implies x=\cfrac{700}{25}\implies x=28

The figures are similar. The area of one figure is given. Find the area of the other figure to the nearest whole number.
Akimi4 [234]

Answer:  Option b.

Step-by-step explanation:

First, you need to calculate the ratio of the area. This is:

ratio=(\frac{64}{28})^2\\\\ratio=\frac{256}{49}

You know that the area of the smaller trapezoid is 771 m², then you can set up the following proportion, where "x" is the area of the larger trapezoid. Then you have:

\frac{256}{49}=\frac{x}{771}

Now you must solve for "x". Therefore, you get that the area of the larger trapezoid is:

 x=(771)(\frac{256}{49})\\\\x=4,028m^2

Find 3 consecutive odd integers whose sum is 225, explain please
aleksklad [387]
3 odd integers have a property that they average up to the middle large one. Let's say we have 3, 5, and 7. 3 is 2 less than 5 and 7 is 2 more than 5. so when you add them it equals 2 times 5. 
After we know that, the sum of 3 odd integers is just 3 times the middle number. ex. 3+5+7 = 3 times 5 = 15
Then we know the some number times three = 225. we find out that the middle number is 75, so the other two are 73 and 77
