Question

5х+[1 +8 х] При х =1,4 пжжжжжжжжжжжжжжжжжж

Answer 1

5х+(1+8х)= 7+1+10.8=18.4 , якщо то модуль тоді скажи

Answer 2

To calculate the value of the expression 5х + [1 + 8х] when х = 1.4, you simply substitute the value of х into the expression and perform the arithmetic.

Given that х = 1.4, let's calculate:

5х + [1 + 8х]

Replace х with 1.4:

5 * 1.4 + [1 + 8 * 1.4]

Now, perform the multiplication and addition:

7 + [1 + 11.2]

Now, add the numbers inside the square brackets:

7 + 12.2

Finally, perform the addition:

19.2

So, when х = 1.4, the value of the expression is 19.2.
