The definition of a function is a relation where every input (x value) is paired with exactly one output (y-value).
A. Not a function, because you have (300, 9) and (300,7). The x-value 300 is paired with two different y-values, 9 and 7.
B. Not a function. (260, 4) and (260, 2)
C. Is a function
D. Not a function. (225, 4) and (225, 2)
X^2 - 4x + 4 = 0
(x - 2)^2 = 0 - Factor left side
x - 2 = 0 - Square root each side
x = 2 - add 2 to each side
Since all the angles<span> congruent, to find the </span>measure<span> of just one </span>angle<span>, divide the </span>sum<span> of all the </span>angles<span> by the number of </span>angles<span>. thats how you find the anwser

Answer:
70m²
Step-by-step explanation:
Area of the plot=½×28×15
= 210m²
Area used by rose plants=⅔×210 =140m²
Area used by marigold=210-140
=70m²
