5. Simplify and solve each of the following equations.
ad + d + 10 = 50
b. 30 - f + 8f = 30
C. -12 = 4e + 23 + e
d. 42 = 32 - 6f-4f
6. Use the formula M = NPQ to solve for the following variables.

b. Solve for o
7. What's the length of a box with a volume of 720 cubic inches, a width of 15
height of 4 inches? (Hint: Isolate the length (L) on one side of the formula

Okay so for every triangle has three angles that always add up to 180 degrees. and to tell the difference between whether they are secure, right or obtuse is that acute: has one angle that is less than 90 degrees. right triangle means there is at least one angle that is exactly 90 degrees. and an obtuse angle has an angle that is bigger than 180 degrees. i’ll do #13 as an example: 13. 40 and 50 so if every triangle has 180 degrees 40+50= 90 degrees then180-90= 90 degrees so the third angle is 90 degrees and because this triangle has a 90 degree angle it means it is a right triangle

72 is the mode because it shows up the most number of times
