(a+b)(c+d)=ac+ad+bc+bd\\\\(x+8)(x+3)=x\cdot x+3\cdot x+8\cdot x+8\cdot3\\\\=x^2+3x+8x+24=x^2+11x+24

Multiply everything in first bracket with the wats in the second so x*x = x^2 and x*3= 3x and 8*x=8x and 8*3= 24.

Confused from where I left off PLEASE help
Leviafan [203]

Not sure the right equation so i did both....

#1 - √12m√15m=1m√2

Simplifies to:

13.416408m2=1.414214m

Let's solve your equation step-by-step.

13.416408m2=1.414214m

Step 1: Subtract 1.414214m from both sides.

13.416408m2−1.414214m=1.414214m−1.414214m

13.416408m2−1.414214m=0

Step 2: Factor left side of equation.

m(13.416408m−1.414214)=0

Step 3: Set factors equal to 0.

m=0 or 13.416408m−1.414214=0

m=0 or m=0.105409

Answer:  m=0 or m=0.105409


#2 - √12m√15m

Simplifies to:

13.416408m2

=13.416408*m2

=13.416408*(m*m)

=13.416408m2

Suppose the sum of two integers is negative. Must both integers be negative? Explain.
mash [69]

Answer:

Not necessarily. There are many ways to write a basic equation with a negative answer. For example, -3-4 = -7. Here 4 is a positive number but because you subtract 4 to 3 or take away 4 from 3 being a negative number and so you get a negative answer. Another example is 6+(-9). There are a couple of ways you can resolve this. My method is to subtract 9 from 6 which gives you 3 and simply add a negative sign.

Let me know if you'd  like more examples. Hope this helps!! Sorry if it is confusing I can explain you in a more simpler way if you'd like.

The seventh grade class is putting on a variety show to raise money. It cost $700 to rent the
Nataly_w [17]

Well, you would need to compensate for the cost of the banquet hall adding an addition $700 to the goal of $1000.

If you need to raise at least $1700 you can write this inequality.

Let x represent the number of tickets sold.

15x≥1700

x≥ 114 (rounded to the nearest whole number because you can't sell half a ticket)

So, at least 114 tickets need to be sold.

(×+2) +(4×-122)=180 need help with this problem
alina1380 [7]
So first you need to open the brackets, so it would be x+2+4x-122=180. Then we can add the 4x and the other x to make 5x, and then by doing 2-122 we get -120. This gives us the equation 5x-120=180. We then isolate the variable by moving the -120 to the other side of the equation and becoming a positive, so it would look like 5x=180+120. Then, we have 5x=300. 300 divides by 5 is 60 making X=60. Hope this helps!
