Answer:

(x+3)+(5+3y)

Step-by-step explanation: In the equation, when you have four terms you group like terms. So 5x+15 by itself and work it out which you will get 5(x+3) and do the same for 3xy+9y answer is 3y(x+3).

Then you will say 5(x+3)+3y(x+3) and then you'll

5(x+3)/(x+3)=5 because you will cancel the (x+3) so the answer would be 5

You will do the same for 3y(x+3)/(x+3)

you will get 3y

Finally, you will take the first equation which is (x+3), and then you'll use the last equation which is (5+3y)

So that's how you will get (x+3)+(5+3y)

*I thought of a number, added 18, then multiplied the result by 8. I got 16. What was my number?
Arte-miy333 [17]

Answer:

-16

Step-by-step explanation:

Represent the number by n.

Then:

8(n + 18) = 16

Performing the indicated multiplication, we get:

8n + 144 = 16

Subtracting 144 from both sides results in 8n = -128.

Dividing both sides by 8:  n = -128/8  =  -16

The number was -16.

Solve -52 = 4m for m
ZanzabumX [31]

Note the equal sign. What you do to one side, you do to the other.


Isolate the variable. Divide 4 from both sides


(-52)/4 = (4m)/4


m = -52/4


m = -13


-13 is your answer for m



hope this helps

Solve the following system of equations. Show all work and solutions.
Hitman42 [59]
  • y=2x²+6x+1
  • y=-4x²+1

Make the equations equal and solve for x

  • 2x²+6x+1=-4x²+1
  • 6x²+6x=0
  • 6x(x+1)=0
  • 6x=0 or x+1=0
  • x=0 or x=-1

For x=0

  • y=-4(0)+1=1

For x=-1

  • y=-4(1)+1=-3

The solutions are

  • (0,1) and (-1,-3)
