That is the vertex form of a quadratic equation
Answer:
1. 24
2. 24
3. -24
4. -24
I don`t know why some of the answers are 10, I think those are just trick ones. The answers are only in 24s
Answer:
3.97 x 10⁸
Step-by-step explanation:
Since there are 6 students with neither brown hair nor blue eyes, the remaining number of students with at least one of the characteristic is 24. The sum of the students with brown hair only, with blue eyes only, and with both should be equal to 24. By letting x be the number of students with both, the equation that would best represent the given is,
(15 - x) + x + (17 - x) = 24
The value of x from the equation is 8.
= 4 = x²
x = Answer: Length= 11 , Brteadth = 2
Step-by-step explanation: Let the breadth of the rectangle be x
length = 9 + x
area = 36 cm²
A.T.Q
36cm² = 9x*x
36 = 9x²
36/9 = 4 = x²
x = root of 4
x= 2
Therefore , breadth of rectangle is 3cm and length is 12 cm
verification:
l*b = 12*3 = 36cm²
