They are equal to one another because 4(3+x) can be rewritten using the distributive property as 4(3)+4x or 3+3+3+3+x+x+x+x
Since you said angle, I assume you mean a triangle, so:
Take the number of the angles you have and add them, then, subtract it by 180. It gives you the missing angle of your triangle!
The correct answer for the question that is being presented above is this one: "A. Division of skin cells every half hour; B. Small graph of y=x squared; C. y= 4 times 3 raised to x; D. y=2x raised to the 3." T<span>hese choices represent an exponential pattern.</span>
The first thing we must do for this case is find the number of total guitarists.
We have then:

We now look for the relationship between the number of guitarists playing jazz alone to the total number of guitarists.
We have then:

Where,
x: number of guitarists playing jazz alone
From here, we clear the value of x.

Then, the number of guitarists who play classical solo is:

Answer:
30 guitarists play classical solos in the contest
36% is the answer to the question
