2. Which algebraic expression represents the following phrase?
oksian1 [2.3K]

The algebraic expression which represents the square of the difference of s and 6 is (s - 6)²

Step-by-step explanation:

Let us represent some words by mathematics expressions

  • Square a number ⇒ x²
  • Square the sum of two numbers ⇒ (x + y)²
  • Sum of the squares of two numbers ⇒ x² + y²
  • Square of difference of two numbers (x - y)²
  • The difference of square two numbers x² - y²

∵ The expression is the square of the difference of s and 6

- That means find the difference between s and 6 at first,

   then square the difference

∵ The difference of s and 6 = s - 6

- Square this difference means but the difference in a bracket

   and then square the bracket

∴ The square of the difference = (s - 6)²

The algebraic expression which represents the square of the difference of s and 6 is (s - 6)²

3.3 by 2.5 + 5.7 by 2.5
den301095 [7]

Answer:

22.5

Step-by-step explanation:

Using PEMDAS, we know that for expressions such as this, we're supposed to multiply before we add. This means that it should look something like this: (3.3 x 2.5) + (5.7 x 2.5). When you solve the multiplication first, you get 8.25 + 14.25. Solve, and you get 22.5. This problem can be solved using any basic calculator, or scratch paper!

What is the volume of the cylinder below?
lbvjy [14]

\qquad\qquad\huge\underline{{\sf Answer}}

Let's solve ~

We need to find volume of the given Cylinder, with information :

  • radius (r) = 12 units

  • height (h) = 17 units

\qquad \sf  \dashrightarrow \:Volume_{(Cylinder)} = \pi r²h

\qquad \sf  \dashrightarrow \:Volume_{(Cylinder)} =  \pi \sdot(12) {}^{2}  \sdot17

\qquad \sf  \dashrightarrow \:Volume_{(Cylinder)} =  \pi \sdot144{}^{}  \sdot17

\qquad \sf  \dashrightarrow \:Volume_{(Cylinder)} = 2448 \pi  \:  \: unit {}^{3}

So, correct choice is B
