I might be wrong but 9
9*2=18
18+7= 25
25 square root = 5
Answer is 9
Answer: No, you cannot.
Step-by-step explanation: A square number cannot be a perfect number.
The numbers: 0, 1, 5, 14, 30, 55, 91, 140, 204, 285, 385, 506, 650, 819, 1015, 1240, 1496, 1785, 2109, 2470, 2870, 3311, 3795, 4324, 4900, 5525, 6201 are examples of perfect numbers.
Answer:the potato is ugly
Step-by-step explanation:because it has marks
Z = 140
X = 40
Y = 40
Explanation:
Z and the angle given (140 degrees) are vertical angles, and are therefore congruent
We know that x and y are vertical angles, so they are also congruent to each other
You know that together, the angles have to add up to 360
140 + 140 + x + y = 360
Another way of putting it:
360-280 = 80
Now, we have to divide by two since we need to find x AND y
80/2 = 40
Therefore, your answers for x and y are 40
To double check, you can add up the angles and see if they equal 360
140 + 140 + 40 + 40
280 + 80 = 360
Answer:
The y-intercept is (0,-12).
Step-by-step explanation:
Given equation is 
.
Now question says to find the y-intercept of the given parabola .
We know that y-intercept means the y-value when x-value equals 0
so let's plug x=0 into given equation then solve that for y.
Hence the y-intercept is (0,-12).
