Answer:
<u>Distributive Property</u>
Step-by-step explanation (if you were to show the steps):
(x+2)(y+z) <u>(first expression)</u>
xy + xz + 2y + 2z <u>(Distributive Property of Multiplication)</u>
yx + 2y + zx + 2z <u>(use the Commutative Property of Addition and Commutative Property of Multiplication to group xy (also known as yx) and 2y together, and to group xz (also known as zx) and 2z together)</u>
y(x + 2) + z(x + 2) <u>(use factoring to get the rewritten expression at the end)</u>
The required equation is :
Now, let's find the required values :
period (p) = 6
[distance between any successive Crest or trough]
a = - 4 (flipped)
b = 2π/p = 2π/6 = π/3
k = -2
Distance of starting position from origin = k
Now, plug in the values ~
Your answer would be 1090 because the formula is 1000(1+.09/1)^1
2x^2 - 2x - 40 = 2x^2 -10x + 8x - 40 = 2x(x - 5) + 8(x - 5)
= (x-5)(2x+8) = 2(x-5)(x+4)
