Question

5a+2b-15a²/3a при a=4 b=-12​

Answer 1

Ответ:

5а + 2b - 15a^2 = 5a( 1 - 3a) + 2b = 5*4 *(1-3*4) + 2*(-12) = -244

Объяснение:

Answer 2

To evaluate the expression 5a+2b-15a²/3a when a=4 and b=-12, we substitute the given values into the expression and perform the calculations:

5a + 2b - (15a² / 3a)

Replacing a with 4 and b with -12:

5(4) + 2(-12) - (15(4)² / 3(4))

Simplifying:

20 - 24 - (15 * 16 / 12)

20 - 24 - (240 / 12)

20 - 24 - 20

-4 - 20

-24

Therefore, when a=4 and b=-12, the expression 5a+2b-15a²/3a equals -24.
