You are subtracting the results in the parenthesis.
I would go with a difference.
Since 8 is being multiplied by 23.6 and -7.8, I would say product.
"A" is the best answer choice.
I hope this helps!

Answer:
k=8/3
Step-by-step explanation:
Let's solve your equation step-by-step.
4k+7=7k−1
Step 1: Subtract 7k from both sides.
4k+7−7k=7k−1−7k
−3k+7=−1
Step 2: Subtract 7 from both sides.
−3k+7−7=−1−7
−3k=−8
Step 3: Divide both sides by -3.
−3k
−3
=
−8
−3
k=
8

You may represent this multiple ways.
1. 66/44 = m
2. 44m = 66
In both of these scenarios you have a total and equal parts.
The first one starts with a total and breaks it into equal parts.
The second choice shows 44 groups of a part totaling 66 meters.
Rate =distance/time
:)
it's the famous d=r*t (distance is rate multiply by time)
therefore, changing the way of expressing the equation d/t =r you can use it to find r
Ok so what you need to know about an octahedron is it's basically two square pyramids stacked on top of each other (one is upside down of course).
The formula for volume of a pyramid is Bh/3.
Base= 8*8=64
Height= 3 each
64*3/3= 64 mm^3 per pyramid.
64*2=128 mm^3 for the octahedron
Final answer: 128 mm^3
