Can anyone help me with this math problem?

f(-2) = 65

Step-by-step explanation:

What f(-2) means is that -2 will be substituted for the value of x, which will result in an output.

f(x) = 6(8-x) + 5

f(-2) = 6(8-(-2)) + 5

f(-2) = 6(8+2) + 5

f(-2) = 6(10) + 5

f(-2) = 60 + 5

f(-2) = 65

Therefore, when x=-2, y=65, which essentially means f(-2) = 65

56.6

step-by-step explanation:

the ratio of the perimeters is equal to the scale.

the ratio of the areas is equal to the square of the scale.

34 / 20 = k

a / 19.6 = k²

substituting:

a / 19.6 = (34 / 20)²

a = 19.6 (34 / 20)²

a ≈ 56.6
