I dont want the answer i just need help pls and thank you please view image
Elis [28]

I can help! With the Greatest Common Factor you figure out the greatest number that can go into all numbers. The number here would be the 2. You then divide 2 by all the numbers in the problem.
You would end up getting x^2 + 6x + 9


I use to struggle with this too. Hope this helps! Have a great day!!

Here's a recipe for pancakes:
sweet [91]

Answer:

Milk: 1000 ml

Flour: 480 g

Butter: 250 g

Step-by-step explanation:

To calculate the amount of butter you have to figure out more flour she used.

First, 480 ÷ 120 = 4 So she uses 4 times the amount of flour.

Then, 60 × 4 = 240

Next, you need the amount of milk so we also multiply by 4.

250 × 4 = 1000

Lastly, have a great day!

11) <br> Solve for x:<br><br> 3(7 + 2x) + 3 = 3(5 + x) − 9(x + 1)
gogolik [260]

Step-by-step explanation:

3(7 + 2x) + 3 = 3(5+ x) - 9(x + 1)

21 + 6x + 3 = 15 + 3x - 9x - 9

6x + 24 = 6 - 6x

12x = -18

x = -1.5
