Answer:

Step-by-step explanation:

Given quadratic equation is,

-32 = 2(x² + 10x)

-32 + 50 = 2(x² + 10x + 25)

18 = 2(x + 5)²

9 = (x + 5)²

± 3 = (x + 5)

x = -2 or x = -8

Hoochie [10]

Given :Enzo wins 5 tickets from every game, and Beatriz wins 11 tickets from every game.We need to find the minimum number of games that Enzo could have played to win the same number of tickets.

The  minimum number of games that Enzo could have played to win the same number of tickets Will be the least common multiple of 11 and 5.

The  factors of 11 and 5 are

11=11x1

5= 5x1

Least common multiply = 11x5=5.

 The minimum number of games that Enzo could have played to win the same number of tickets is 55.

a park is in the shape of a rectangle 8 miles long and 6 miles wide. how much shorter is your walk if you walk diagonally across
lesya [120]
You need to use this particular formula
a^2 + b^2 = c^2
this allows you to solve for the sides of a triangle which is what the diagonal would look like if u were to draw it. a equals the width of the park and b equals the height of the park.
6^2 + 8^2 = c^2
next you need to multiply 6 by the power of 2
36 + 8^2 = c^2
then the same for the 8
36 + 64 = c^2
then add the numbers together.
100 = c^2
after you add you get the square root of 100 which is 10. a square root is 2 numbers that multiply together to equal a particular number. square root is what you do to cancel out a power of 2
so if you walk diagonally you go 10 miles instead of 14 miles leaving a difference of a whole 4 miles.

spayn [35]

Answer:

56 packs of crazy straws

Step-by-step explanation:

1. 224 x 2= 448 *the total straws*

2. Once you have that, Divide the 448 by 8 so you can find out the packages he started with. You get 56.

3. Check your work by doing 56 x 8, which is 448, just to make sure.

4. Divide 448 by two which gives you 224, which is what you started with.

There are 36 students in the class 1/6 students are wearing blue shirts and 2/3 are wearing white shirts how many are wearing a
Marat540 [252]

Answer:

The answer would be 1/6 kids are wearing shirts that are neither blue or white.

Step-by-step explanation:

So, to make this easier, lets convert 2/3 to a same denominator fraction.

We must ask, how many times does 3 go into six?

We multiply 3 by 2 and get six. We then multiply the numerator of 2 by the same, getting 4.

Our new fraction is 4/6 which is equal to 2/3.

Then we add 4 to 1, making it 5. That is the amount of students wearing blue and white shirts, which means

1/6 of the kids in the class are wearing shirts that are neither white nor blue.

Hope this helps,
