Absolute value make it positive
15-|-5|=15-5=10
|-4|+6=4+6=10
-|7+3|=-|10|=-(10)=-10
|-10|=10
so it is -|7+3| that doesn't belong
Answer:
what i think number 7 would be 5
Step-by-step explanation:
Answer:
Step-by-step explanation:
Is it 25
Use the sine theorem:
sin(angle A) / length of side a = sin (angle B) / lenght of side b
Here:
angle A = 32°
length of side a = length from school to library = x
angle B = 110°
length of side b = 2.2 mi
Then, sin(32°) / x = sin(110°) / 2.2 mi
=> x = 2.2 mi * sin (32) / sin (110)
x = 1.24 mi
Therefore the answer is the option B. 1.2 mi
Answer:
4th option
Step-by-step explanation:
The given expression is:

In order to simplify this expression we have to multiply and divide it with the conjugate of the denominator i.e multiply and divide the entire expression with
, as shown below:

Thus, 4th option gives the correct answer.
