Answer:
The answer is -12
Step-by-step explanation:
2xy + 3x + 4x + 3 if x = 5 and y = -5
Now,
2xy + 3x + 4x + 3
2(5)(-5) + 3(5) + 4(5) + 3
-50 + 15 + 20 + 3
38 - 50 = -12
Thus, The answer is -12

Answer:
$39,851.25
Step-by-step explanation:
If the sales increase at a rate of 9% per year, this means it will be 109% of the previous year's value since 100% + 9% = 109%
109% in decimal form = 109/100 = 1.09
Therefore, the exponential function is:
, where
is the number of years
So when
,

After 8 years, annual sales = $39,851.25
Area is the length times the width.
When you know the area and one of the dimensions, divide the area by the known dimension to find the other one.
133 / 11 = 12.09
The room needs to be at least 12.09 feet wide. ( round answer if needed).
The formula for area of a circle is π x r^2
r = radius = 7 cm.
Area = 7^2 x π
Area = 49π cm²
