Answer:
n = -5, 3.
Step-by-step explanation:
n^2 + 2n - 15 = 0
Let's check if we can factor this quadratic:
We need 2 numbers whose product is -15 and whose sum is +2.
There are 2 such numbers and they are +5 and -3, so the factors are:
(n + 5)(n - 3) = 0.
n + 5 = 0 or n - 3 = 0
therefore the zeroes are -5 and 3.
Answer:
Step-by-step explanation:
From the question we are told that:
Slant Height of Kite 
Angle 
Since Emma,The Kite and Andrew forms a right angle triangle
Generally the equation for distance between Andrew from Emma is mathematically given by
Answer:
this is how u solve this
Step-by-step explanation:
4 (0.5f - 0.25) = 6 + f
2.0f - 1.0 = 6.0 + f
1.00f = 6.0 + f
f = -5.0

You put the x=6
6³-4(6)²-12(6)+15=15
