The equation of a straight line is y = 20 – X.

Reptile [31]

Given:

The equation of a straight line is

$y=20-x$

The x value of a point on the line is 14.

To find:

The y value of this point.

Solution:

If a point (x,y) lines on line, then the equation of line must be stratified by that point.

We have, the equation of a straight line.

$y=20-x$

Putting x=14, we get

$y=20-14$

$y=6$

Therefore, the y-value is 6 when the x-value is 14.

A rectangle with sides 12 cm and 14 cm has the same diagonal as a square.

adelina 88 [10]

Answer:

Length of side of square $=\sqrt{170}$

Step-by-step explanation:

Sides of rectangle $=12,14\ cm$

let $x$ be diagonal of rectangle

Pythagorean theorem : The square of hypotenuse is equal to sum of square of sides.

Here hypotenuse $=x$

$x^{2} =12^{2}+14^{2}\\x^{2} =144+196\\x^{2} =340\\x=\sqrt{340}$

Diagonal of square $=\sqrt{340}$

let side of square $=a$

again use pythagorean theorem

$340=a^{2}+a^{a}\\2a^{2}=340\\a^{2}=170\\a=\sqrt{170}$
