how can you solve quadratic equation in one variable using factoring method?​

Answers

Answer 1
Take a quadratic equation in standard form:
If there exists a sum of two numbers that equal b, whose addends produce a product that equals c. You can rewrite the quadratic as a product of two binomials.


For example take
When thought through throughly, -5 had addends, -2 and -3 that produce 6 when multiplied
Thus, we can rewrite the quadratic as.

A bushel had a total of 68 apples. 25% of the apples were green and the rest of the apples were red. How many more red apples were there than green? STEP BY STEP EXPLANATION PLS

Answers

17 apples were green because it’s 25 percent of apples so it’s 68-17
1. You need to do percentages so to find 25% or 1/4 of 68 (68 is divisible by 4) that would be 17
2. There are 17 green apples
3. There are 51 red apples
4. 51-17= 34
5. There are 34 more red apples than green

Hendrick's Honda is having a contest to win a new Honda Civic. To win a chance at the car, you must guess the number of keys in a jar within 5 of the actual number. The people who are within this range get to try a key in the ignition of the Civic. Suppose there are 697 keys in the jar.

Answers

Answer:

The valid range is 697 to 702

Step-by-step explanation:

The question is incomplete; However, the requirement would likely be to determine the valid range which users can guess

Given

[tex]Keys = 697[/tex]

[tex]Difference = 5[/tex]

First, we need to determine the minimum

[tex]Minimum = Keys - Difference[/tex]

[tex]Minimum = 697 - 5[/tex]

[tex]Minimum = 697[/tex]

Next, we determine the maximum

[tex]Maximum = 697 + 5[/tex]

[tex]Maximum = 702[/tex]

Hence:

The valid range is 697 to 702

how far would a 4.0 cm tall object be located from a reflecting surface with a focal lenght that is equal to 5 cm if it is to create an image seen 15 cm behind the mirror. Determine the image size​

Answers

Answer:

HERE IS YOUR ANSWER

Step-by-step explanation:

Use the mirror equation:

1/di + 1/do = 1/f

where di = -10 cm and f = +15 cm. (Note that di is negative if the image is virtual.)

Substitute and solve for do.

1/do + 1/(-10 cm) = 1/(15 cm)

1/do = 1/(15 cm) - 1/(-10 cm) = 5/(30 cm)

do = 6 cm

Joanne has 20 books on crafts and cooking. she has 6 more cookbooks than craft books. how many of each does she have?​

Answers

Answer:

Crafts books: 7

Cookbooks: 13

Step-by-step explanation:

Let x be the crafts book

Let y be the cookbooks

Solve for x:

Plug x and y in: x + y = 20Re-write: y = x + 6Plug in x + 6 instead of y: x + x + 6 = 20Combine like terms: 2x + 6 = 20Subtract 6 from each side, so it now looks like this: 2x = 14Divide each side by 2 to cancel out the 2 next to x. It should now look like this: x = 7

Solve for y:

Re-use an equation from above: y = x + 6Plug in the value of x: y = 7 + 67 + 6 = 13So, y = 13

Find m angle MOP if m angle MON =4x+9 and m angle MOP =3x-3

Answers

Answer:

33

Step-by-step explanation:

Measure of ∠MOP is equals to 71.7°.

What are supplementary angles?

" Supplementary angles are those angles whose sum is equals to 180°."

According to the question,

∠MOP = 3x - 3

∠MON = 4x + 9

As ∠MOP and ∠MON has common arm OM.

Therefore, ∠MOP and ∠MON are supplementary angles.

As per definition of supplementary angles we have

∠MON + ∠MOP = 180°

Substitute the value of ∠MOP and ∠MON  we get,

 4x + 9 + 3x - 3= 180°

⇒7x - 6 = 180°

⇒7x = 174

⇒ x = 24.9 (round off)

Substitute the value of x in measure of ∠MOP we get,

∠MOP = 3(24.9) -3

          = 71.7°

Hence, measure of ∠MOP is equals to 71.7°.

Step-by-step explanation:

the probability that a student is taking calculus given that he or she is taking statistics.

Let C = Calculus

S = Statistics

We solve this above Question nursing the formula;

P ( C ∪ S) = P(C) + P ( S ) - P ( C ∩ S)

From the question,

P(C) = 0.10

P( S ) = 0.18

P ( C ∩ S) = 0.02

P ( C ∪ S) = ???

P ( C ∪ S) = 0.10 + 0.18 - 0.02

= 0.28 - 0.02

a^2+9=25 subtract nine from both sides

a^2=16

find the square root of 16 which is 4

Answer:

4 cm

Step-by-step explanation:

Using Pythagoras' identity in the right triangle.

The square on the hypotenuse is equal to the sum of the squares on the other 2 sides.

let x be the length of the 3 rd side, then

x² + 3² = 5²

x² + 9 = 25 ( subtract 9 from both sides )

x² = 16 ( take the square root of both sides )

He lets his brother have 1/3 of his collection and takes 27 cards to school to give his friends. How many baseball cards remain in Ryan's collection? 127 cards 90 cards 117 cards 126

Answers

Answer:

117 cards

Step-by-step explanation:

Total number of cards in the collection of Ryan = 216

Number of cards given to his brother = ⅓ of 216 = ⅓ × 216 = 216/3 = 72

Number of cards given to his friend at school = 27

Number of baseball cards that Ryan has remaining = 216 - (72 + 27)

= 216 - 99

Number of cards remaining = 117 cards
