Step-by-step explanation:
basically b = square root x times c
b= x
x= 2
c= 2+7 or the full length
Answer:
a) 8x^2 + 4x + 9
Step-by-step explanation:
To find the total number of red and pink geranium pots, we need to add the two expressions given for the number of pots for red and pink respectively.
x (7x - 2) + (x + 3)^2
Expanding x (7x - 2) gives (7x^2 - 2x)
Expanding (x + 3)^2 gives (x^2 + 6x + 9)
Adding the like terms in these two expanded expressions:
(7x^2 - 2x) + (x^2 + 6x + 9)
= 7x^2 + x^2 + 6x - 2x +9
8x^2 + 4x + 9
The point is in Quadrant III; I know that because of the " - " sign.
The angle from the positive x-axis counterclockwise from zero is pi plus pi/3, or 4pi/3.
The x-coordinate of the point is then 4 cos 4pi/3, or -2.
The y-coordinate of the point is 4 sin 4pi/3, or -3.46.
Check: Is the Pyth. Thm. satisfied here? Does (-2)^2 + (-3.46)^2 = 4^2?
Yes. That comes out to 15.97, which is close enough to verify these 2 coordinates are correct.
The answer to this is compound inequality, (-4,8)
