Answer:
-4
Step-by-step explanation:
adding a negative is the same as subtracting a positive
Answer: 24
8 + (-12) = -4
-4 + (-20) = -24
-24 + 24 = 0
0 + 4 = 4
20 + 4 = 24
the expression for the perimeter would be
2(x) + 2(2x+7)
which can be simplified to 2x+4x+14
which equals 6x+14
A. -11
In the function, replace x with -2
R(x) = x^2 - 3x - 1 ➡ R(-2) = (-2)^2 - 3 × 2 -1 = -11
