Answer:
C. he did not multiply the numerator by 2
Step-by-step explanation:
To find an equivlent fraction, you must multiply the numerator and denominator by the same thing.
Answer: D. 8x² + x + 3
Sum means the answer to an addition problem. To find the sum of polynomials, we will add like terms.
<h2>What are like terms?</h2>
Like terms can be combined using addition or subtraction and have the same variables. Constants are also like terms with each other because they have no variables.
<h2>Solve</h2>
(4x² + 1) + (4x² + x + 2) Starting equation from the question
= 4x² + 1 + 4x² + x + 2 Remove brackets
= 4x² + 4x² + x + 1 + 2 Rearrange to group like terms together
= 8x² + x + 1 + 2 Add like terms with the same 'x²' variables
= 8x² + x + 3 Add like terms that are constants

Answer:
Step-by-step explanation:
Let the original number = x
x=98.0
x=98
Answer:
The x-intercept is the location on the graph when the output is 0.
f(x) > 0 is intervals of the domain where the graph is above the x-axis.
y-intercept is the location on the graph when the input is 0.
f(x) < 0 is intervals of the domain where the graph is below the x-axis.
If the radius r of the circle is known, the segment length would be 2*pi*r*5/16 or r*5pi/8. (Circumference of the circle times the fraction that’s in the sector.)
