Answer:
1) 40
2)9x-12
3)42
Step-by-step explanation:
1) A square has 4 sides, and if one side's length is 10, the perimeter (distance around the square) is 10 times 4=40
2) Simply add these values together to get 9x-12
3) Plug in 6 as x in 9x-12. (6*9)-12=54-12=42
F(12)=-34(12)+2
f(12)=-408+2
f(12)=-406
You would keep the first fraction the same , turn the division sign into a multiplication sign , and flip the 2nd fraction upside down.
10/14 ÷ 7/16
10/14 x 16/7= 80/49 = 1 31/49
-3.7 is greater than -3.8, but is it not less than of equal to -3.8
