The discriminant is b^2 -4ac
a = 1
b = -2
c = 4
discriminant = 4 -4 * 1 * 4 =
4 -16 =
-12
I get MINUS 12 as the answer but that isn't one of the choices.
5): Rectangular Flowerbed
Total Area:
14m * 10m
140m^2
Flower Bed Area:
10m * 6m
60m^2
Area of Path:
140m^2 - 60m^2
Answer ======> 80m^2
4): Area of Parallelogram: 4.5m^2
Area = B * H =====> 2.5m * 1.8 ====> 4.5m^2
b Base of the parallelogram ====> 2.5m
h Height of the parallelogram ======> 1.8m
Answer ======> Area ======> 4.5m^2
Hope that helps!!!! Numbers 5 and 4 is done for you!!!!
