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
In order to figure this out, you must solve the equation.
1-6x=7 (given)
-6x=6 (subtract 1 from both sides)
X=-1 (divide both sides by -6)
The answer is no.
Fish A is 2 inches and fish B is 4 inches
There are 72 different ways the director can fill the positions.
(1+2+3+4+5+6+7+8) x 2
You multiply it by 2 because there are going to be 4 other people who will not have a position, and 8/4 is 2.
