HI,
So, 35% of 20 = 7...
Do you want the steps on how to figure that out?
Answer: 18 (b)
Step-by-step explanation:
3x6=18
Answer:6
Step-by-step explanation:at first calculate (-3)^2=9
then 9+2=11
finally the answer is 11-5=6
5 cars and 9 motorbikes had their tires changed.

14-9=5 cars
9×2=18 5×4= 20 (add together) = 38 tires
1) Answer: 
<u>Explanation:</u>
The equation of an ellipse is:
; where (h, k) is the center, "a" is the x-radius, and "b" is the y-radius.
Center Radius
x-axis: (10 + -10)/2 = 0 10 - 0 = 10
y-axis: (2 + -2)/2 = 0 2 - 0 = 2
Now, input the values into the equation:

2) Answer: 
<u>Explanation:</u>
Vertices are: (0, 1) and (0, -5) ------> x-values are the same, y = 1, -5
Covertices are: (-1, -2) and (1, -2) ----> y-values are the same, x = -1, 1
Center Radius
x-axis: (-1 + 1)/2 = 0 1 - 0 = 1
y-axis: (1 + -5)/2 = -2 1 - (-2) = 3
Now, input the values into the equation:
