Answer:
70
Step-by-step explanation:
Area of a kite, is to multiply the two diagonals and divide by 2:
p(diagonal) * q(diagonal) / 2
pq / 2.
P = 14
Q = 10.
(14 * 10) / 2
140/2

Answer:
see below
Step-by-step explanation:
0 = x^2 + 6x – 10
Add 10 to each side
10 = x^2-6x
Take the coefficient of x
-6
Divide by 2
-6/2 =-3
Square it
(-3)^2 =9
Add 9 to each side
10+9 = x^2-6x+9
We use -3 for the square term
19 = (x-3)^2
Take the square root of each side
±sqrt(19) = x-3
Add 3 to each side
3±sqrt(19) = x
