Answer: The answer is x^2+2xy+2y^2–3x–3y–1
Step-by-step explanation: Move 2 to the left of y^2.
Answer:
x = 38.2°
Step-by-step explanation:
<u> sin 27° </u> = <u> x° </u>
11 15
15 · (sin 27°) = 11 · x°
cross-multiply:
6.81 = 11x
6.81 / 11 = x
x = 0.619
sin^-1 (0.619) = 38.2°
Answer:
area of trapezium in terms of x=1/2*x(x+3+x+1)
Step-by-step explanation:
Reflection over the y-axis and shifted 3 units up
The correct answer is C. Sample survey
Explanation:
A sample survey is a study method that involves selecting a portion of a population and asking questions to these individuals to know their opinions or insights about a particular situation. Additionally, the answers provided by the selected individuals are used to make conclusions about all the population.
