Step-by-step explanation:
=a.ooo78
#3: 15
#4: 13.2
#5: 5.44 (curious as to how you guessed 7)
#6: 7
#7: 7.3
#8: 15
#9: You'd round 0.9 to 1 and 3.78 to 4. 4/1 = 4
#10: Round 2.5 to 3. 36/3 = 12
#11: If they want you to round 0.25 down to 0, then 7/0 is undefined.
#12: 9.5 rounds to 10 142.5 rounds to 143. 143/10 = 14.3
#14: 24.8 cm divided by 175 = approximately 0.1417 cm per year. Round that up to approximately 0.14 per year.
We need to distribute the term 4x to x - 6. Basically, we need to multiply 4x by x, which gives us 4x², and 4x by -6, which gives us -24x. Putting our two derived terms together, we get 4x²- 24, which is your answer. Hope this helps and have a great day!
Okay so we gotta do whats in the lines first so 6+14 that’s gonna be 20 but the add the 70 and it’s gonna be 90
