Answer:
108 square feet
Step-by-step explanation:
First you want to break up the "L" into two parts. These parts can be seens as a and b. You need to find out the length on the left hand side, and half of it is 6ft as seen, so if half of it is 6ft, then you need to find the other half, which is obviously 6ft. 6+6=12, and to find the area of the thinner rectangle, multiply 2*24=48. That would be the area of section a. Section b is the bottom section and what you want to do is multiply 10*6 because this is how you would find the area of section b, which would be 60. 60+48=108. I know I was not very descriptive but I still hope this somewhat helps. I also might be wrong because of the fact that it says surface area despite the fact that this shape is 2D.
Many simple inequalities can be solved by adding, subtracting, multiplying or dividing both sides until you are left with the variable on its own.
But these things will change direction of the inequality:
Don't multiply or divide by a variable (unless you know it is always positive or always negative)
Answer:
Step-by-step explanation:
In this equation what is strange is probably using the letter a as the unknown, but this is a matter of choice we could have calle y or z for that matter. Then we will treat it ans any other equation and solve it.
-11 -5a = 6(5a+4)
-11 -5a= 30a + 24
-11 - 24 = 30a + 5a (placing the unknown a in the rght side and the numbers in the left to solve the equation)
- 35 = 35a
-35/35 = a
- 1= a
