(-3) + 7 = 4
You can use a number line by simply starting at 7 then moving back 3 spaces because it's negative. Then you will get positive 4.
Hello,
3^x+1=15
==>3^x=14
==>x*ln(3)=ln(14)
==>x=ln(14)/ln(3)
==>x=2,40217350273....
Step-by-step explanation:
i) answer =1
ii) 2 <u>-3m + 6n -2</u> x 3 <u>3-m</u>
First, you need to do the distubutive property, you should get 18m+30=66. Then you could subtract 30 from both sides. Then, you should get 18m = 36. You will then divide both sides by 18. Your answer should be m = 2. Hope this helps!
