In pretty sure this is right i apologize if not I havent done this in a couple of years.
Answer: D
Step-by-step explanation:
(x-9)² = x-3
(x-9) (x-9)= x-3
x² - 9x-9x +81 = x-3
x² -18x+81 =x-3
x²-19x+84 =0
(x-12)(x-7)=0
x=12 or 7
Answer:
75
Step-by-step explanation:
Let x represent the number of bullfrogs in the population.
We have been given that in a study of the population density of bullfrogs, 25 are captured and marked in the first sampling. Five days later, 30 frogs are captured, 10 of which have marks.
We will use proportion to solve our given problem as:
Therefore, the estimated number of bullfrogs in the population would be 75.
Answer:
m<C = 119°
Step-by-step explanation:
Create an equation to find the value of x.
(9x - 26)° = (2x - 12)° + (4x + 43)° (exterior angle theorem of a ∆)
Solve for x
9x - 26 = 2x - 12 + 4x + 43
Add like terms
9x - 26 = 6x + 31
9x - 6x = 26 + 31
3x = 57
Divide both sides by 3
x = 19
✔️m<C = 4x + 43
Plug in the value of x
m<C = 4(19) + 43
m<C = 76 + 43
m<C = 119°
