D
area of a rectangle = length × width
area = (2x + 3)(x - 4) ( expand using FOIL )
= 2x² - 8x + 3x - 12 = 2x² - 5x - 12 → D
Answer:
Step-by-step explanation:
We'll need the actual prices of one of the objects to figure it out...
but I've worked it out here in relation to each object....
Marker = 1/3 x cost of the pen
Marker = 1/3 x 1/3 x cost of book = 1/9 x cost of the book
Marker = 1/3 x 1/3 x 1/3 x cost of game = 1/27 x cost of the game
This probably isn't what you're looking for, but maybe it'll help?
Hi,
Answer: - 15
<u>My work:</u> To easily achieve this problem take your number -11 and add it with negative 4. When you do this you get your answer - 15. This problem can be easily solved in 2 steps.
<u><em>My Numerical work:</em></u>
1. - 11 + -4
2. -15
I Hope I Helped!
Answer:
m∠1 = 67
Step-by-step explanation:
22. The range of the arcsine function (sin⁻¹(x)) is [-π/2, π/2]. The function will return π/4 for arcsin(sin(3π/4)) = arcsin(1/√2).
The sine function does not pass the horizontal line test, so it has no inverse over its entire domain. The arcsine function is only the inverse of the sine function over a limited domain/range.
25. sin(cos(π/2)) = sin(0) = 0.
As with any nested function evaluation, you evaluate the inner function first.
... cos(π/2) = 0
Then you evaluate the outer function.
... sin(0) = 0
