Answer:
y = x² − 6x − 27
Step-by-step explanation:
To distribute, you can use something called FOIL. It stands for First, Outer, Inner, Last.
First, multiply the First term in each factor.
x · x = x²
Now multiply the Outer terms in each factor.
x · 3 = 3x
Next multiply the Inner terms in each factor.
-9 · x = -9x
Finally, multiply the Last terms in each factor.
-9 · 3 = -27
Add them all up:
x² + 3x − 9x − 27
x² − 6x − 27
1 yard = 3 feet
2 yards = 6 feet
3 yards = 9 feet
area= L(W)
6(9)= 54 square ft
The plot of land has an area of 54 square feet.
Answer:
12.5%
Step-by-step explanation:
The price increased from 800 to 900. So what is the PERCENTAGE INCREASE??
The increase is 900 - 800 = 100
To find this in terms of original, we need to divide 100 by 800 and multiply by 100 to get the "percentage". Let's do it:
So the increase is 12.5% and thus the general sales tax is 12.5%
Answer:
There are three basic trigonometric ratios: sine , cosine , and tangent .
Step-by-step explanation:
If something is to the power of 1/2, it is the same as the square root of that number. So, what's the square root of 49?
