Question

-0,3х - 13xy2 - 37xy2, если х= 4, y = -0,2.​

Answer 1

Ответ:

- 9.2

Объяснение:

После преобразования будет

-0.3*4-13*4*0.04-47*4*0.04

Посчитав будет

-1.2-2.08-5.92=9.2

Answer 2

To evaluate the expression -0.3x - 13xy^2 - 37xy^2, we substitute x = 4 and y = -0.2 into the expression:

-0.3(4) - 13(4)(-0.2)^2 - 37(4)(-0.2)^2

Simplifying further:

-1.2 - 13(4)(0.04) - 37(4)(0.04)

-1.2 - 13(0.16) - 37(0.16)

-1.2 - 2.08 - 5.92

= -9.2

Therefore, when x = 4 and y = -0.2, the value of the expression -0.3x - 13xy^2 - 37xy^2 is -9.2.
