Question

if x=2/5 find the value of 2x+4x+2​

Answer 1

Answer:

4.4

Step-by-step explanation:

2*2/5+4*2/5+2

4/5+8/5+2

4+8+10/5

22/5

4.4

Answer 2

Answer:

$Hence\:required\:value\:is\:\bold{\boxed{4\frac{2}{5}}}$

Step-by-step explanation:

Given that,

x = 2/5

Therefore,

2x + 4x + 2

Now, putting the value of x in the above expression, we get,

$=2*\frac{2}{5}+4*\frac{2}{5}+4\\\\=\frac{4}{5}+\frac{8}{5}+4\\\\=\frac{4+8+10}{5}\\\\=\frac{22}{5}\\\\=4\frac{2}{5}$

$Hence\:required\:value\:is\:\bold{\boxed{4\frac{2}{5}}}$
