Simplify the expression: 3x2⋅x2=<br><br><br> a<br><br>3x<br><br> b<br><br>3x4<br><br> c<br><br>3x2+2
DedPeter [7]

Answer:

The quadratic equations and their solutions are;

9 ± √33 /4 = 2x² - 9x + 6.

4 ± √6 /2 = 2x² - 8x + 5.

9 ± √89 /4 = 2x² - 9x - 1.

4 ± √22 /2 = 2x² - 8x - 3.

Explanation:

Any quadratic equation of the form, ax² + bx + c = 0 can be solved using the formula x = -b ± √b² - 4ac / 2a. Here a, b, and c are the coefficients of the x², x, and the numeric term respectively.

We have to solve all of the five equations to be able to match the equations with their solutions.

2x² - 8x + 5, here a = 2, b = -8, c = 5.                                                  x = -b ± √b² - 4ac / 2a = -(-8) ± √(-8)² - 4(2)(5) / 2(2) = 8 ± √64 - 40/4.     24 can also be written as 4 × 6 and √4 = 2. So                                                                                     x = 8 ± 2√6 / 2×2= 4±√6/2.

2x² - 10x + 3, here a = 2, b = -10, c = 3.                                                   x =-b ± √b² - 4ac / 2a =-(-10) ± √(-10)² - 4(2)(3) / 2(4) = 10 ± √100 + 24/4. 124 can also be written as 4 × 31 and √4 = 2. So                                                                              x = 10 ± 2√31 / 2×2 = 5 ± √31 /2.

2x² - 8x - 3, here a = 2, b = -8, c = -3.                                                    x = -b ± √b² - 4ac / 2a = -(-8) ± √(-8)² - 4(2)(-3) / 2(2) = 8 ± √64 + 24/4.     88 can also be written as 4 × 22 and √4 = 2. So                                                                             x = 8 ± 2√22 / 2×2 = 4± √22/2.

2x² - 9x - 1, here a = 2, b = -9, c = -1.                                                     x = -b ± √b² - 4ac / 2a = -(-9) ± √(-9)² - 4(2)(-1) / 2(2) = 9 ± √81 + 8/4.                                          x = 9 ± √89 / 4.

2x² - 9x + 6, here a = 2, b = -9, c = 6.                                                    x = -b ± √b² - 4ac / 2a = -(-9) ± √(-9)² - 4(2)(6) / 2(2) = 9 ± √81 - 48/4.                                                                             x = 9 ± √33 / 4 .

A department store sells a pair of shoes with an 87% markup. If the store-bought the pair of shoes for $55.25, what is the selli
olga_2 [115]
Answer: $103
Explanation:
Stores will markup an item to make a profit so this question is asking how much they will be selling the shoes to the customer.
To solve this problem we will start by multiplying the price the store payed for (55.25) by the percentage in decimal form (.87)
55.25•0.87=48.0675

We then add the markup to the price payed for the shoes.
55.25+48.0675=103.3175

When rounding to the nearest dollar we look at the digit in the tens place (3) and since 3 is < 5 we round the final price to $103

1.) Number of Total People = 1387

In Figure 1, Red boxes represent "<span>Teens" which is 10 in number whereas Blue boxes represent "Adults".

1 box contains = 1387/19 = 73

Number of Teens = 73 * 10 = 730 

<span>In short, Your Final Answer would be: 730 
</span></span>
2.) Number of Total Chocolates = 1440 

In Figure 2, Red boxes represent "<span>Chocolate flavor ice-cream" which is 6 in number whereas Blue boxes represent "Vanila".

1 box contains = 1440/15 = 96

Number of Chocolate Ice-creams = 96 * 6 = 576

<span>In short, Your Final Answer would be: 576
</span></span>
3.) Number of Total Sodas = 576

In Figure 3, Red boxes represent "<span>diet sodas" which is 5 in number whereas Blue boxes represent "Regular sodas".

1 box contains = 576/12 = 48 sodas

Number of diet cokes = 48 * 5 = 240 

<span>In short, Your Final Answer would be: 240 

Hope this helps!</span></span>
