Answer:
Step-by-step explanation:
Simplifying
2x + 13 = 0
Reorder the terms:
13 + 2x = 0
Solving
13 + 2x = 0
Solving for variable 'x'.
Move all terms containing x to the left, all other terms to the right.
Add '-13' to each side of the equation.
13 + -13 + 2x = 0 + -13
Combine like terms: 13 + -13 = 0
0 + 2x = 0 + -13
2x = 0 + -13
Combine like terms: 0 + -13 = -13
2x = -13
Divide each side by '2'.
x = -6.5
Simplifying
x = -6.5
Answer:
28
Step-by-step explanation:
Check the picture below.
you surely know how to get the area of a rectangle, well, there you have 6 of them, get the area of each, sum them up, that's the surface area of the prism.
You take a right triangle and find the lengths of the two sides that are vertical and horizontal. Then, using the formula a^2 + b^2 = c^2, find the length of C
(aka: Hypotenuse)
Start: 10:50 am
Plus the 20 minutes would be 11:10 am
11:10 am plus the 14 minutes would be 11:24 am
The end time is 11:24 a.m.
And the elapsed time would be a total of 34 minutes
