Answer:
The answer is
Step-by-step explanation:
Given: f(x) = 3 + 2x - x²
To compute f(3 + h) substitute x = 3 + h.
Similarly, to compute f(h) simply substitute x = h.
We are asked to compute
f(3 + h) = 3 + 2(3 + h) - {(3 + h)²}
= 3 + 6 + 2h - {9 + 6h + h²}
= 9 + 2h - 9 - 6h - h²
= - 4h - h²
Now, f(h) = 3 + 2h - h²
f(3 + h) - f(h) = -4h - h² - 3 - 2h + h²
= -6h - 3
which is the required answer.
Answer:
308025 times larger
Step-by-step explanation:
The polygon BBB is a scaled copy of polygon A using a scale factor of 555.
This means for every length of polygon AAA, polygon BBB is 555 times larger.
Recall area is in .
Area of polygon BBB = (scale factor)^2 multiplied by area of polygon AAA
Since the scale factor is 5
Area of polygon BBB = (555^2) * Area of polygon AAA
Area of polygon BBB = 308025 times the area of polygon AAA
