2x, 6x, 12x, 24x, I that these are all of them
C. Multiplication and B. Subtraction
Answer:
D.
Step-by-step explanation:
A is linear, you can figure out that y=x+5
B is linear, y=22(x+1)
C is linear, y=8x+5
D is exponential, y=3ˣ⁺¹
Deriving these formulas is a matter of trial and error if you know you can choose between linear and exponential.
Answer:
Perimeter of a triangle = add all sides
Both the legs of the isosceles triangle are always EQUAL.
x+4x-6+4x-6 = 60
9x-12 = 60
9x = 60+12
9x = 72
x = 8
