Question

4(15х+8)+3(6х-5)При х = 4

Answer 1

4(15x+8)+3(6x-5)=60x+32+18x-15=78x+17
x=4
78x+17=78*4+17=312+17=329

Answer 2

To evaluate the expression 4(15x+8) + 3(6x-5) when x = 4, we substitute the value of x into the expression and perform the calculations.

Let's substitute x = 4:

4(15(4) + 8) + 3(6(4) - 5)

First, we simplify the expressions inside the parentheses:

4(60 + 8) + 3(24 - 5)

Next, we perform the multiplications:

4(68) + 3(19)

Now, we calculate the products:

272 + 57

Finally, we add the results:

272 + 57 = 329

Therefore, when x = 4, the value of the expression 4(15x+8) + 3(6x-5) is 329.
