Answer 2

3.5*a*a*a + 2*c*c = 3.5 * (-27) + 2 * 16 = 94.5 + 32 = 126.5

Ответ: 126.5

Answer 3

To evaluate the expression 3a^3 + 2c^2 when a = -3 and c = -4, we simply need to substitute the values of a and c into the expression and perform the calculations.

Given: a = -3 c = -4

Now, let's substitute these values into the expression:

3(-3)^3 + 2(-4)^2

Now, follow the order of operations (BODMAS) to perform the calculations:

Step 1: Evaluate the exponents first.

-3^3 = -3 * -3 * -3 = -27 (-4)^2 = -4 * -4 = 16

Step 2: Perform the multiplications.

3 * (-27) = -81 2 * 16 = 32

Step 3: Perform the addition.

-81 + 32 = -49

So, the value of the expression 3a^3 + 2c^2 when a = -3 and c = -4 is -49.
