(3x-5)(2x+7) =
= 3x·2x + 3x·7 - 5·2x - 5·7
= 6x² + 21x - 10x - 35
= 6x² + 11x - 35
Answer:

Step by step explanation:
Let d represent the rate of temperature decrease in degrees Celsius per day from Monday to Thursday.
As temperature decreased at a constant rate in the next 3 days, so the rate of temperature will decrease 3d degree Celsius in 3 days.
We are told that the pool was open on Monday. The high temperature was
on Monday. So the decrease in temperature from Monday to Thursday will be
.
We have been given that the swimming pool is open when the high temperature is higher than
.
As the pool was closed on Thursday. This means that temperature on Thursday was less than or equal to 20 degree Celsius. We can represent this information in an inequality as:

Therefore, the inequality
can be used to determine the rate of temperature decrease in degrees Celsius per day, d, from Monday to Thursday.
Answer:
The real-life distance to the nearest mile between Tampa and Orlando is 88 miles
Step-by-step explanation:
String distance between Fort Myers and Miami = 7 inches
A real life distance between Fort Myers and Miami = 154 miles
So, 7 inches = 154 miles

Scale : 1 inch = 22 miles
String distance between Tampa and Orlando = 4 inches
Using scale
The real-life distance to the nearest mile between Tampa and Orlando = 
Hence The real-life distance to the nearest mile between Tampa and Orlando is 88 miles
Answer:
x = 2
Step-by-step explanation:
distribute:
8(4) - 8(x) = 7x + 2
32 - 8x = 7x + 2
add 8x to each side to get:
32 = 15x + 2
subtract 2 from each side to get:
30 = 15x
x = 30/15 or 2
