i am going to answer question 1, so q1 is a number line
Step-by-step explanation:
Let the 1st number be x
2nd number = x + 2
3rd number = x + 4
4th number = x + 6
5th number = x + 8
x + x + 2 + x + 4 + x + 6 + x + 8 = 20
5x + 20 = 20
5x = 20 - 20
5x = 0
x = 0 ÷ 5
x = 0
The 5 consecutive integers are
0, 2, 4, 6, 8
3cd^2(6cd + 14cd^2)
18cd^3 + 42cd^4
Answer:
The proportion is 
= 
, and the length of the unknown side is 
or 27.22 approximately rounded to the nearest hundredth.
Step-by-step explanation:
Since the triangles are similar, the proportion of corresponding sides are equal. The pairs of corresponding sides in these triangles which we'll use to solve it are LK, KE, MK, and KF. LK and KE are corresponding sides, and their proportion is . MK and KF are corresponding sides, and their proportion is in which x represents the missing side. The proportions are equal, so = . Multiply both sides by 84 to isolate the variable, and you'll get 
, which is 
or .
