2 terms on left side, 3 on right side

9.

All variables count as coefficients,  so they’d be 8m, k, and -16k

10.

Each month for 7 months, Eve reads 3 books. How many more books does she need to read before she has read 30 books?
enot [183]
How many books has she read so far? She's been doing this for 7 months, so so far she's read:

7*3=21

how many does she still need to read?

30-21=9

so she needs to read 9 more books. With 3 books a month, this means:

9/3=3

so she needs to read 9 more books, which will take her 3 months!

Find the area of the regular octagon if the apothem is 4.2 and a side is 3.4 In. Round to the nearest whole number. A. 114 B. 57
Elena-2011 [213]
The area of the regular octagon is calculated as half of the product of the perimeter and the apothem (ap), using the formula of the area of the regular polygon.
 We have then:
 A = ((p) * (ap)) / 2
 Where,
 p: perimeter
 ap: apotema
 Substituting values:
 A = ((8 * 3.4) * (4.2)) / 2
 A = 57.12 in ^ 2
 Answer:
 
the area of the regular octagon is:
