Answer:

So, we conclude that Mark is right.

Step-by-step explanation:

If we have the following expression: 15 - (37 + 8) : 3.

We will first divide the value we get in parentheses and then subtract it.

Because sharing is an older mathematical operation than subtraction. Therefore, we get:

15-(37+8):3=15-45:3=15-15=0

So, we conclude that Mark is right.

Evaluate the function.
telo118 [61]

f(x) = x² - 2x - 7

f(-1), this means that x = -1.

Since you need to find f(-1), substitute/plug in -1 into "x" in the function:

f(x) = x² - 2x - 7       Plug in -1 into "x"

f(-1) = (-1)² - 2(-1) - 7

f(-1) = 1 + 2 - 7

f(-1) = -4          Your answer is B
