200 because I looked it up
The answer is x equals 2.
Answer:
400/81 cm²
Step-by-step explanation:
FE : DC
1 : 3
Since area ABCD = 400
s² = 400
s = 20
FE = ⅓(20) = 20/3 cm
IH : FE
1 : 3
IH = ⅓(20/3) = 20/9 cm
Area of HIJK:
(20/9)² = 400/81 cm²
Since the function y= f(x) is decreasing on the interval (5, 7), y = -f(x) is INCREASING on the interval (5,7), because the slope is inverted due to the negative sign.
