x=18.78
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

B=90
I think this is the answer
To find the answer, multiply the decimal by 10. 0.05 X 10 = 0.5, and since 0.05 goes into 0.5 10 times, it is equivalent to 1/10th of 0.5.
Answer:
Option (A)
Step-by-step explanation:
Volume of a cylinder is given by the formula,
V = πr²h
Here r = radius of the cylinder
h = height of the cylinder
Therefore, volume of a cylinder given in the question,
V = π(
)²(8)
= 648π
= 2035.8 km²
Volume of the given cylinder is 2035.8 km².
Option (A) will be the answer.
