The opposite of a negative number is the positive number, so 1 1/2 would be the answer <span />
Answer:
C
Step-by-step explanation:
The area (A) of the triangle is calculated as
A = bh ( b is the base and h the perpendicular height )
The triangle is equilateral , since 3 angles = 60°
Then base AB = 12
Find height CD using the sine ratio in the right triangle ( there are 2 )
sin60° = = = = ← exact value of sin60° ( cross- multiply )
2CD = 12 ( divide both sides by 2 )
CD = 6
Then
A = × 12 × 6 = 6 × 6 = 36 units² → C

Answer:
r= -5 , r= 17
Step-by-step explanation:
5|-6+r|=55
solve for 'r'
First we isolate absolute function
We divide both sides by 5
|-6+r| = 11
for absolute function we consider two cases, one with positive and one with negative. Now we make two equations
-6+r = 11 or -6+r = -11
Now solve both equations
-6 + r= 11
Add 6 on both sides
so , r= 17
-6 + r= -11
add 6 on both sides , so r= -5
