What is the sum of 15 and its additive inverse?
In Mathematics, the additive inverse of a number is defined as the number that when it is added to a specific number equals 0
From the above question, the additive of 15 = -15
Therefore, the sum of 15 and its additive inverse is calculated as:
15 + -15
= 15 - 15
= 0

Answer:
triangular prisim
Step-by-step explanation:
this is a triangular prisim because if you can see that the shape is a triangle and then is put into 3D. A cone is a circular shape. A rectangular prisim has a rectangular shape.
4(2r + 8) = 88
mutiply the bracket by 4
(4)(2r)(4)(8)= 8r+32
8r+32= 88
Move +32 to the other side
Sign changes from +32 to -32
8r+32-32= 88-32
8r= 88-32
8r= 56
divide by 8 for both sides
8r/8= 56/8
Cross out 8 and 8, divide by 8. Then becomes r
r= 7
Answer: r= 7
