The plot: x meters wide and (x+30) meters long with an area of 15000 m^2. the equation you're searching for is:
x meters * (x+30) meters = 15000 m^2 or
x^2 + 30x m^2 = 15000 m^2 and
x^2 + 30x - 15000 = 0 <== that's the equation.
ans: x^2 + 30x - 15000 = 0
Answer:
g(-12) = -7
Step-by-step explanation:
They are used for making the sides of a triangle into a ratio. Sine is opposite of the angle divide by the hypotenuse, cosine is adjacent divided by the hypotenuse, and tangent is the opposite divided by the adjacent. Sine is the y-component, cosine is the x-component, and tangent is the ratio of sine/cosine or can also be considered the slope.
Answer:
-3/2
Step-by-step explanation:
Given the funtion
(2x+3)² - 6x+9 = 0
(2x+3)² = 6x + 9
Expand
4x²+12x+9 = 6x + 9
4x²+12x - 6x = 0
4x²+6x = 0
4x² = -6x
4x = -6
x = -6/4
x = -3/2
Hence the value of x is -3/2
