Which description matches the algebraic expression 45n
2 answers:
Answer: The correct description is (C). the product of a number and 45.
Step-by-step explanation: We are given to select the correct description that matches the algebraic expression 45n.
Let, 'n' be a number.
Then, the sum of 'n' and 45 is written as (45 + n).
So, option (A) is incorrect.
The quotient of 'n' and 45 is given by
So, option (B) is incorrect.
The product of 'n' and 45 is
45 × n = 45n, which means 45 times of a number 'n' or n times of 45.
So, option (C) is correct.
The difference of 'n' and 45 is (n - 45) or (45 - n), according as 'n' is greater or 45 is greater.
So, option (D) is incorrect.
Thus, the correct option is (C).

4^{3} + 8^{2} + \sqrt{9}
iii) (\frac{4}{5})^{2}. \sqrt[3]{8} \leqx^{3} - 3x + 6 \leq \sqrt{\frac{1}{3}}
Step-by-step explanation:
i)
\frac{3}{5} + (- \frac{1}{2}) = \frac{6}{10} - \frac{5}{10} = \frac{1}{10}
ii)
4^{3} + 8^{2} + \sqrt{9}
iii) (\frac{4}{5})^{2}. \sqrt[3]{8} \leqx^{3} - 3x + 6 \leq \sqrt{\frac{1}{3}}
