Heather is building a ladder for her tree house. She will need 13 feet of lumber for each stilt and 2 feet of lumber for each rung on the ladder. How many feet of lumber does she need for a ladder with 2 stilts and 12 rungs? 29 feet because 2 + 13 + 12 + 2 = 29
50 feet because 2 (13) + 12 (2) = 50
160 feet because 13 (12) + 2 (2) = 160
210 feet because (2 + 13) (12 + 2) = 210

B. 50

Step-by-step explanation:

For two stilts, you'd multiply 13 by two.

2(13) = 26

For twelve rungs you multiply 2 by 12.

12(2) = 24

Then you add the two numbers together to see how much would she needs.

24 + 26 = 50

This gives you the answer, which is equivalent to B.

correct answer:

a + bi

you ignore the remainder, therefore the answer is y = x+2

step-by-step explanation:

you have to divide the denominator by the numerator. you can use synthetic division or long division.

[-5] .     1 .     7 .     11

x + 2 + 1/x+5
