To factor 3x + 9 you should know that 3 is a common factor of both 3 and 9, so you can factor 3 out in both numbers like this.
3x + 9
3(x + 3)
When you factor out 3 on both numbers you should know that 3 X 3 = 9 and since you factored out 3 there would be another 3 left so you would have the answer: 3(x + 3)
Here is another equation that might help:
24x + 36
Since 12 is a common factor of both numbers, factor 12 out of the equation:
12 (2x + 3)
You know that 12 x 2 = 24 and that 12 x 3 = 36
And since you can't factor out anymore numbers because 2 and 3 doesn't have any common factors with each other you get the answer:
12 (2x + 3)
Answer:
4.88
Step-by-step explanation:
sinA=opposite/adjacent
sin24=x/12
12(0.40673664307)=x
x=4.88083971691
Answer:
B n>2
Step-by-step explanation:
−6n<−12
Divide each side by -6, remembering to flip the inequality
-6n/-6 > -12/-6
n >2
Answer:
7z
Step-by-step explanation:
4z-(-3z).
Two negatives equal a positive only <u>when they are right next to each other.</u>
4z+3z=7z. Hope this helps :D
5 units because your starting from (-2,-2) so the last -2 will stay and the first number(-2) will go up until you hit the (,3) which will be 5 units away
