Answer:
4x^2 + 30x - 2 = 0Step-by-step explanation:
Q2:
Here the area of the painting and frame = (2x+7)*(2x+8) = 4x^2 + 30x + 56, which is equal to 58 square units.
Thus, 4x^2 + 30x + 56 = 58
Therefore, 4x^2 + 30x + 56 - 58 = 0
The correct answer is:
4x^2 + 30x - 2 = 0
Q3: Here g(x) is exponential function because in g(x) the rate of increasing is fast.
Therefore, the correct answer is
g(x), because it eventually exceeds f(x)
