The points at which a quadratic equation intersects the x-axis are referred to as x intercepts or zeros or roots of quadratic equation
Given :
The points at which a quadratic equation intersects the x-axis
The points at which the any quadratic equation crosses or touches the x axis are called as x intercepts.
At x intercepts the value of y is 0.
So , the points at which a quadratic equation intersects the x-axis is also called as zeros or roots of the quadratic equation .
The points at which a quadratic equation intersects the x-axis are referred to as x intercepts or zeros or roots of quadratic equation

#5) 7.065 sq. ft.
#6) 36 ft
#7) 200.96 sq. ft.
#8) 176.625 sq. ft.
Explanation
#5) Converting 18 inches to feet, 18/12 = 1.5. The area of the circle would be given by A=3.14(1.5)² = 3.14(2.25) = 7.065 sq. ft.
#6) The radius is 18 inches, so the diameter is twice that: 18*2 = 36 inches. Converting this to feet, we have 36/12 = 3 feet. Each stone is 3 feet across. Laying 12 of them against each other would give us a total length of 12*3 = 36 feet.
#7) The radius of the entire mirror with frame is 20/2 = 10. The area of the entire mirror with frame is A=3.14(10²) = 3.14(100) = 314 in².
The area of the mirror without the frame is A=3.14(6²) = 3.14(36) = 113.04 in².
The difference between the two will give the area of the frame:
314-113.04 = 200.96 in²
#8) The area of the circular region is given by A=3.14(7.5²) = 176.625 ft²
Answer:
OPTION D
Step-by-step explanation: PLS MARK BRAINLIEST :D
Answer:
8-2x I think
Step-by-step explanation:
You would first divide 39 by 3, ( 2 + 1 = 3) and get 13.
You would next take 5 away from 13 and get 8.
Then you have your answer, because you cannot simplify it more because both the numbers do not have the same variable.
Answer:
and Liz can ship maximum 19.6 pounds.
Step-by-step explanation:
Let the possible weight of the medium flat-rate box = w pounds.
It is given that there is a box weighing 6 ounces i.e. 0.375 pounds.
Plus, the maximum weight of the package is 20 pounds.
So, we get,
The inequality representing the situation is,
Weight of medium box + 0.375 pounds ≤ Maximum weight of the package
i.e.
i.e. 
i.e. 
Thus, Liz can ship maximum 19.6 pounds.
