What two numbers add up to 20 but multiply to 75?

Answers

First you find all the numbers that multiply to get 75.

75 x 1
25 x 3
15 x 5

Then find out which two add together to get 20.

75 + 1 = 76
25 + 3 = 28
15 + 5 = 20

So the answer would be 15 and 5.

15 and 5 because 15 times 5 is 75 and 15 plus 5 is 20

Simplify the rational expression. State any restrictions on the variablen^4-10n^2+24/ n^4-9n^2+18

Answers

Answer:

The simplified form is $=((n-2)(n+2))/((n-\sqrt3)(n+\sqrt3))$

The variable n can not be equals to $\pm\sqrt3$ as for these value denominator equals to zero which becomes an indeterminate form.

Step-by-step explanation:

we have to simplify the rational expression and state the restrictions on the variable.

$(n^4-10n^2+24)/(n^4-9n^2+18)$

We can now see that both the numerator and denominator are quadratic trinomials in $n^2.\$

We split the middle terms as follows;

$(n^4-10n^2+24)/(n^4-9n^2+18)=(n^4-6n^2-4n^2+24)/(n^4-3n^2-6n^2+18)$

$=(n^2(n^2-6)-4(n^2-6))/(n^2(n^2-3)-6(n^2-3))$

$=((n^2-4)(n^2-6))/((n^2-6)(n^2-3))$

$=((n-2)(n+2))/((n-\sqrt3)(n+\sqrt3))$

which is the simplified form of given expression.

The variable n can not be equals to $\pm\sqrt3$ as for these value denominator equals to zero which becomes an indeterminate form.

The answer to the question is n^2-4/n^2-3 n ≠±√6±√3

A girl scout troop sold cookies. If the girls sold 5 more boxes the second week than they did the first, and if they doubled the sales of the second week for the third week to sell a total of 431 boxes of cookies, how many did they sell each week?They sold _____ boxes the first week, _____ boxes the second week, and ____ boxes the third week.

Answers

So,

We have three placeholders.

x, y, and z will represent the number of cookie boxes they sold for the first, second, and third weeks, respectively.

"The girls sold 5 more boxes the second week than they did the first."
x + 5 = y

"They doubled the sales of the second week for the third week."
z = 2y

"To sell a total of 431 boxes of cookies"
x + y + z = 431

Now we have our three equations.
x + 5 = y
z = 2y
x + y + z = 431

Obviously, we can substitute y and z in the last equation, because the other two open sentences tell us what they are.
x + (x + 5) + 2(x + 5) = 431
x + x + 5 + 2(x + 5) = 431

Collect Like Terms.
2x + 5 + 2(x + 5) = 431

Distribute.
2x + 5 + 2x + 10 = 431

Collect Like Terms.
4x + 15 = 431

Subtract 15 from both sides.
4x = 416

Divide both sides by 4.
x = 104

Now we can use the other two original sentences to figure out what y and z are.
x + 5 = y
104 + 5 = y
109 = y

z = 2y
z = 2(109)
z = 218

Now, to check, add x, y, and z.
x + y + z = 431
104 + 109 + 218 = 431
213 + 218 = 431
431 = 431 This checks.

The Girl Scouts sold 104 cookie boxes on the first week, 109 boxes on the second week, and 218 boxes on the third week.
