Answer:
Missing side=25 units.
Area of the figure= 470 sq units.
Step-by-step explanation:
The figure is made up of a rectangle and a triangle.
To get the base of the triangle, we find the difference between the two parallel sides, that is, 16ft and 31 ft.
31ft-16ft=15ft
The height of the triangle is 20 since it is parallel and equal to the length of the rectangle.
We therefore use pythagoras theorem to find ?
a²+b²=c²
15²+20²=c²
625=c²
c=25
ii. The figure is a trapezium therefore we use the following formula to find the area.
A= 1/2(a+b)h, where a and b are the two parallel sides. and h the distance between them.
=(1/2)(31+16)×20
=470 sq units
Hello there!
How are you doing today? I hope you are doing at least "okay".
g(x) = x³ + 2x² - x - 2
To find the zeros or the roots of a function, you need to set the function equal to 0 then solve for x.
x³ + 2x² - x - 2 = 0
Factor left side of the equation
(x + 1)(x - 1)(x + 2) = 0
Now we can set factors equal to 0
x + 1= 0 or x - 1 = 0 or x + 2 = 0
x= 0 - 1 or x = 0 + 1 or x= 0 - 2
x= -1 or x = 1 or x = -2
Thus,
The roots or the zeros of the function are:
-2, -1, 1
As always, it is my pleasure to help students like you!
