Answer:
you have to use the knowledge and vertically opposite angles corresponding angles
vertically opposite meaning the angle vertically opposite to 84 is at 4 then corresponding angles to get what is 2x then divide your answer by 2
The letters can be added together if they have similar variables.
B and C are like terms. Option B shows the like terms of letters.

What is a binomial?</h3><h3>
</h3>
A mathematical expression consisting of two terms connected by a plus sign or minus sign is called the binomial expression.
The attachment shows the table of letters and variables.
To multiply binomials, a form of the distributive property is used.
The table has been complete with the final values of letters which are given below.








From the final values of letters, B and C are the only like terms, they can be added together since they have similar variables.
Hence we can conclude that B and C are like terms. Option B shows the like terms of letters.

Answer:
- boat: 15 mph
- current: 5 mph
Step-by-step explanation:
The relation between time, speed, and distance is ...
speed = distance/time
__
The speed downstream is ...
downstream speed = (100 mi)/(5 h) = 20 mi/h
The speed upstream is ...
upstream speed = (100 mi)/(10 h) = 10 mi/h
The boat's speed in still water is the average of these:
boat speed = ((downstream speed) + (upstream speed))/2 = (20 +10)/2 mi/h
boat speed = 15 mi/h
__
The speed of the current is the difference between the travel speed and the boat speed:
current speed = downstream speed - boat speed
= (20 mi/h) - (15 mi/h)
current speed = 5 mi/h
Answer: A & C
The dimensions of the larger cylinder are 3 times the dimensions of the smaller cylinder.
If proportional dimensional changes are made to a solid figure, then the surface area will change by the square of the scale factor of similar solids.
