Answer:
The factors of given equation is
Step-by-step explanation:
Given equation
We have to determine the factors of given equation.
Quadratic equation is an equation with highest degree 2.
Consider the given quadratic equation
We can solve the quadratic equation using middle term splitting method.
splitting middle term can be done by writing middle term in such a way that the product of coefficient is the product of remaining two terms.
29x can be written as 30x-1x
Taking 5x common from first two terms and -1 from last two terms , we have,
Thus, the factors of given equation is
40

D. 23.6 in.2
B. 114
C. 122
D. 314
E. 192
Answer:
C. 122
Step-by-step explanation:
Given,
Dimension of the cake:
Length = 12 in Width = 16 in Height = 4 in
We have to find out the area of the tray that is not covered by the cake.
Indra centered the cake on a circular tray.
Radius of the tray = 10 in.
So area of the tray is equal to π times square of the radius.
Framing in equation form, we get;
Area of tray =
Since the cake is placed in circular tray.
That means only base area of cake has covered the tray.
Base Area of cake =
Area of the tray that is not covered by the cake is calculated by subtracting area of base of cake from area of circular tray.
We can frame it in equation form as;
Area of the tray that is not covered by the cake = Area of tray - Base Area of cake
Area of the tray that is not covered by the cake =
Hence The area of the tray that is not covered by the cake is 122 sq. in.
