A property of rectangles is that opposite sides are congruent. In this case, since QT and RS are opposite sides, they are equal to each other. With this knowledge, you can form the equation 
to solve for x.
Firstly, subtract both sides by 8: 
Next, divide both sides by 4 and your answer will be 
, or the third option.
Answer:
-1
Step-by-step explanation:
Rewrite i 14 as ( i 4 ) 3 × i 2 . If i = √ − 1 , then i 2 = − 1 .
From here ( i 2 ) 2 = ( − 1 ) 2 , so i 4 = 1 . If i 4 = 1 ,
then we can say that: i 14 = ( 1 ) 3 × i 2 = i 2 = − 1
Answer:
-4
Step-by-step explanation:
-4(-4) + 5 > 17
16 + 5 = 21 > 17
Answer:
(B)Stratified
Step-by-step explanation:
Stratified sampling refers to a sampling method in which the entire population is first divided into groups/strata before a random sample is taken from each strata.
The school population in this case has been divided into these strata,
- Sophomore class
- Junior class; and
- Senior class
From these classes, a random sample of 49,39 and 48 students respectively was then taken,
