Question

3.4х+5.7х+6.6х-4. при х=36

Answer 1

3.4*36=122.4
5.7*36=205.2
6.6*36=237.6
122.4+205.2+237.6-4=565.2-4=561.4

Answer 2

To evaluate the expression 3.4x + 5.7x + 6.6x - 4 when x = 36, we substitute the value of x into the expression and perform the calculations.

Replacing x with 36, we have:

3.4(36) + 5.7(36) + 6.6(36) - 4

Calculating each term:

3.4(36) = 122.4 5.7(36) = 205.2 6.6(36) = 237.6

Now, substituting these values back into the expression:

122.4 + 205.2 + 237.6 - 4

Combining like terms:

565.2 - 4

Performing the subtraction:

561.2

Therefore, when x = 36, the expression 3.4x + 5.7x + 6.6x - 4 equals 561.2.
