What is the output of the fuction f(x)=x+21 if the input is 4

1 answer:

5 0

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]

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

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

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

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

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

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

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

Multiply or divide. Show your work. 3n²-n/n²-1÷n²/n+1

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.
