=16.7332
That is one side of the square, so multiply by 4
=66.93
Area: 20 x 30 so 600
perimeter: 20 + 20 + 30 + 30 = 100
The answer would be the last option. :)
3136
There are 32 weeks in a year. If you were not to use multiplication, you can use addition to find the answer.
If he delivers 98 papers a week and there are 32 weeks in a year, then you can add 98 to itself 32 times:
98+98+98...
Do this until you have added 98 to itself 32 times. This will give you the answer of 3136.
Answer:
x = -11
Step-by-step explanation:
3(1 - 3x) = 2(-4x + 7)
Distribute the 3.
(3 - 9x) = 2(-4x + 7)
Distribute the 2.
3 - 9x = -8x + 14
Add 8x to both sides.
3 - x = 14
Subtract 3 from both sides.
-x = 11
Multiply by -1.
x = -11.
Proof:
3(1 - 3x) = 2(-4x + 7)
3(1 - 3(-11)) = 2(-4(-11) + 7)
3(1 + 33) = 2(44 + 7)
3(34) = 2(51)
102 = 102
