Answer:
5a^2 +2a
Step-by-step explanation:
Like terms are ones with the same exponent of x. They can be combined.
3a^2 +2a +2a^2
= (3a^2 +2a^2) +2a
= (3+2)a^2 +2a
= 5a^2 +2a
The sum of the measures of the angles in a triangle is 180°.
Therefore we have the equation:
2x° + 3x° + 55° = 180°
5x° + 55° = 180° <em>subtract 55° from both sides</em>
5x° = 125° <em>divdie both sides by 5</em>
x° = 25°
<h3>Answer: x = 25</h3>
The answer is a number that can be written as a ratio of two integers. The answer is C.
Answer:
V=785.4
Step-by-step explanation:
V=pi*r^2*h
V=pi*5^2*10
V=pi*25*10
V=pi250
V=785.39=785.4
