Hey user☺☺
Option a is correct
Because the graph has only one solution.
As the graph touches the x-axis at one point that means that it will have only one solution for x. But we know that a quadratic equation has two solutions. So the graph will have two equal solution amd therefore the discriminant will be 0.
Hope this will help☺☺
Answer:
The maximum value of the quadratic is 9, it's the very top point or the vertex.
Answer:
(40+2b)cm
Step-by-step explanation:
Complete question
Jimmy is putting up a fence around his rectangular garden. One side of the garden is 20 feet long, and b represents the width, How much fencing material will he need.
To get the amount of fencing material needed, we will find the perimeter of the fence
perimeter of the fence = 2(L+W)
L is the length
W is the width
Given
Length = 20feet
Width = b feet
perimeter of the fence = 2(20+b)
perimeter of the fence = 2(20) + 2b
perimeter of the fence = 40+2b cm
Hence the amount of material needed will be (40+2b)cm
Answer:
12x(2x2^3)=120
Step-by-step explanation:
12x2+2^3=120
(12x2)+2^3=32
12x(2+2^3)=?
12x(2+8)=?
12x10=120
