Answer:
L = 15
Step-by-step explanation:
P = 2L + 2W
you know that P = 50, W=10
So you have to replace those values on the equation
50 = 2L + 2*(10) --> Replace P and W
50 = 2L + 20 --> Multiply and now you are going to separate the unknown and the constants.
Remember that if you send a constant to the other side of the equal the sign will change to its opposite
50 - 20 = 2L --> Solve the constants
30 = 2L --> Now for the L, you have to leave it alone, so the 2 that is multiplying you have to send it to the other side of the equal but with the opposite operation, the opposite operation of multiplying is dividing, so you have:
30/2 = L
L= 15

Answer:
Step-by-step explanation:
To use the order of operations stands for (Parenthesis, Exponents, Multiply, Divide, Add, and Subtract) from left to right.
First, do parenthesis.
17(-12+3)
(-12+3)=-9
17(-9)
Then, multiply.
17*9=153
17(-9)=-153
-153
The correct answer is -153.
He started with 3.
3 X 3 = 9.
9 - 5 = 4.
4 X 4 = 16.
16 - 7 = 9.
9 divided by 3 = 3.
3 + 6 = 9.
