The largest triangle and the triangle whose hypotenuse is x are similar. So:
(21 + 4)/x = x/4
Cross multiply:
x^2 = 100
x = 10
Your answer is incorrect. It should be 10, not 20.
Answer:
A dependent variable is a factor that changes because of procedures conducted on the independent variable
Step-by-step explanation:
Using a cause and effect analogy, the independent variable is the causal variable. The independent variable or variables are the variables on which what is being measured, has no effect, and it is the variable the investigator manipulates to find the effect on the dependent variable.
The dependent variable are the variables that shows he effect of the changes made and manipulations to the independent variable. The dependent variable is therefore, the effect variable
Therefore, the correct option is ' A dependent variable is a factor that changes because of procedures conducted on the independent variable'
Answer:
Step-by-step explanation:
Step-by-step explanation:
By Factor Theorem, we have:
(x - 1)(x - 2)(x - 3)(x + 3)
= (x² - 3x + 2)(x² - 9)
= x⁴ - 3x³ - 7x² + 27x - 18.
