6x+36

<span>You need to find a common divisor of both numbers( 6 and 36).
In this case 6 is of course divisible by 6 and 36 is also divisible by 6.
So you divide 6x by 6 we are left with an x and if you divide 36 by 6 we are left with 6.
So factored is: x+6</span>

Well you cant really solve that because it doesnt equal anything, however, you can factor it. In factored form it would be 6(x+6). If the equation was 6x+36=0 then you subtract 36 on both sides and get 6x=-36. Then you divide by 6 and x=-1

Answer: 2x^2-7x-15

Step-by-step explanation:

reorder the terms (x*2+3)*(x-5)

multiply the parentheses

(2x+3)*(x-5)

collect like terms (2x^2-10x+3x-15)

product= 2x^2-7x-15

Is 104.12 greater than 104.002

Liono4ka [1.6K]

Yes, 104.12 is greater than 104.002

because 104.12 rounds up to 104.1
and 104.002 rounds up to 104.0

Place the pantomino on 5 numbers they must equal 490 so to check if it would work just add them first if it's not possible explain how it's not possible

Casey bought 3 books and an 7 CD's and paid $79. Her friend Jane bought a 5 books and 2

I am Lyosha [343]

Answer:

book $3
CD $10

Step-by-step explanation:

We can let b and c represent the cost of a book and the cost of a CD, respectively. Then the purchases can be described by ...

3b +7c = 79

5b +2c = 35

Using Cramer's rule to find the solution, we have ...

b = (7(35)-2(79))/(7(5) -2(3)) = 87/29 = 3

c = (79(5)-35(3))/29 = 290/29 = 10

The cost of each book was $3; the cost of each CD was $10.

_____

Cramer's rule tells you the solution to ...

ax +by = c

dx +ey = g

is ...

x = (bg -ec)/(bd -ea)

y = (cd -ga)/(bd -ea) . . . . same denominator

This solution is fully equivalent to using elimination or substitution to solve the problem. Using these formulas effectively "cuts to the chase" without all the intermediate steps. The cross-multiplying pattern of differences is not hard to memorize.
