Answer:
1017in^3
Step-by-step explanation:
Answer:
Three values that would make this true would be 5, 9, and 20.
You could choose any number that is greater than or equal to 5
Notice the picture below
thus, we know the total area is 70 square meters
now, if we add those areas, it should give us 70
thus
(5x)+(40)+(5x)=70 solve for "x"
Answer:
Step-by-step explanation:
Without brackets, we are not exactly sure what is under the root sign. There are 3 choices.
sqrt(x) + 2 - 15 = - 3
sqrt(x + 2) - 15 = - 3
sqrt(x + 2 - 15) = - 3
I think the middle one is what you intend. If not leave a note.
sqrt(x + 2) - 15 = - 3 Add 15 to both sides.
sqrt(x + 2) - 15+15 = - 3+15 Combine
sqrt(x + 2) = 12 Square both sides
x + 2 = 12^2 Do the right
x + 2 = 144 Subtract 2 from both sides.
x + 2-2 = 144-2
x = 142
