Question

find the value of x if ,8x = 23 square - 17 square​

Answer 1

Answer:

30

Step-by-step explanation:

there are 2 ways of doing this

the first one is,

23^2 = 529

17^2 = 289

529 - 289 = 240

x = 240/8

x = 30

The second way is to use the formula (a+b)(a-b)= a^2 - b^2

= 23^2 - 17^2 = (23+17)(6)/8 = 40/8 x 6 = 30

Hope this helps

• Find the value of x if 8x = $\rm{{23}^{2} - {17}^{2}}$

✬To Find✬

• Value of x = ?

✬Solution✬

$\to \sf{8x = {23}^{2} - {17}^{2}}$

$\to \sf{8x = 529 - 289}$

$\to \sf{8x = 240}$

$\to \sf{x = \large \cancel \frac{240}{8}}$

$\to \sf{x =30}$

$\text{Therefore,the value of x is} \: \underline \bold{{30}}.$
