a) Shawn's error was that he Multiplied 15 by 2x only. He didn't Multiply 15 by 7
b) The difference, in square feet, between the actual area of Shawn’s garden and the area found using his expression is given as 98 square feet
<h3>What is the perimeter?</h3>
The perimeter is defined as the sum of all the sides of the figure. Now we have The area in, square feet, of Shawn’s garden is found be calculating 15(2x + 7). Shawn incorrectly says the area can also be found using the expression 30x + 7.
The correct area =15(2x + 7).
= 30x + 105 square feet
The error in Shawn’s expression is
= 15(2x + 7)
= 30x + 7 square feet
Shawn's error was that he Multiplied 15 by 2x only. He didn't Multiply 15 by 7
The difference, in square feet, between the actual area of Shawn’s garden and the area found using his expression is given as
30x + 105 square feet - 30x + 7 square feet
= 30x + 105 - (30x + 7)
= 30x - 30x + 105 - 7
= 98 square feet

Answer:
B. Any integer greater than 0
Step-by-step explanation:
The domain of a function is the complete set of possible values of the independent variable. It is the set of all possible values of t which will make the function "work", and will give a result for the Air Pressure, P(t).
Since Time(t) is a continuous function, the domain could take on any positive real number. Since, we are looking for the best description of the domain, Option B (any integer greater than 0) would be suitable.
This is because choosing any real number in Option A will accept negative values and time cannot be negative.
The answer is answer choice B,
B) {-2, -1, 0, 1}

Use you brain. Please use it.
Just use the distributing property and combine like terms. There isn’t a definite answer since it is an expression.
