Mathematics

To solve this equation, plug your input value into the function to find your output.

This would leave you with:
f(4)=4+21

Add the two integers together:
f(4)=25

So he output value of that function with he input of 4 would be 25.

25x power square - 36 y power square​
finlep [7]

\implies {\blue {\boxed {\boxed {\purple {\sf {  (5x + 6y)(5x - 6y) }}}}}}

\large\mathfrak{{\pmb{\underline{\orange{Step-by-step\:explanation}}{\orange{:}}}}}

={25x}^{2}  - 36 {y}^{2}

=  ({5 \times 5)x}^{2}  -  (6 \times 6){y}^{2}

=  ({5x})^{2}  -(  {6y})^{2}

= (5x + 6y)(5x - 6y)

<h3><u>Note</u>:</h3>

{a}^{2}  -  {b}^{2}  = (a + b)(a - b)

Ugo [173]
\frac{3n^{2} - n}{n^{2} - 1} \div \frac{n^{2}}{n + 1}
\frac{n(3n) - n(1)}{n^{2} + n - n - 1} \div \frac{n^{2}}{n + 1}
\frac{n(3n - 1)}{n(n) + n(1) - 1(n) - 1(1)} \div \frac{n^{2}}{n + 1}
\frac{n(3n - 1)}{n(n + 1) - 1(n + 1)} \div \frac{n^{2}}{n + 1}
\frac{n(3n - 1)}{(n - 1)(n + 1)} \div \frac{n^{2}}{n + 1}
\frac{n(3n - 1)}{(n - 1)(n + 1)} * \frac{n + 1}{n^{2}}
\frac{3n - 1}{n - 1} * \frac{1}{n}
\frac{3n - 1}{n(n - 1)}

Both the diameter and height of a cylinder vase are 2.5 times greater than a dimilar vase. The surface area of the smaller vase
faust18 [17]

Both diameter and height are scaled by 2.5.

Area is measured in squared units ( square centimetres).

Square the scale factor:

2.5^2 = 6.25

Multiply the area of the smaller vase by the scale:

2826 x 6.25 = 17,662.5 square cm.
