Find the unknown side length, x. Write your answer in simplest radical form.
A. 4
B. V65
C. 11
D. 5 V13

B √65

Step-by-step explanation:

the triangle on the right

3²+x²=5²

9+x=25

25-9+=16

√16=4

now plug that into the triangle on the left

4²+7²=x²

16+49=x

16+49=65

√65 is the answer

arithmetic sequence

step-by-step explanation:

given that a sequence has terms as

19, 15, 11,

this is represented on a graph

the pattern indicates that the sequence is an arithmetic sequence with i term

a=19 and common difference d =-4

any general term

thus the sequence is reduced by 4 for each successive term starting from 1 and nth term is

24-5n.

first negative term would start after 5th term

5th term =24-25< 0

from 5th term onwards the sequence would be negative.

a. the are of the rectangle is 18.25

b. 18.25 times two is 36.50
