are you sure its b? b doesnt seem to be present in 2x-y=6
Answer:
A)
B) $1200
Step-by-step explanation:
Let w represent employee's weekly sales and be total weekly earnings.
We have been given that a phone store employee earns a salary of $450 per week plus 10% commission on her weekly sales.
A) The total weekly earnings of employee would be weekly salary plus 10% of weekly sales.
10% of weekly sales, w, would be
Therefore, the function models the employee's weekly earnings.
B) To find the weekly sales in the week, when employee earned $570, we will substitute in our formula and solve for w as:
Therefore, the amount of employee's weekly sales was $1200.
(4x² + 2y)(3x + y²<span>) =
12x</span>³ + 4x²y² + 6xy + 2y³
<span>The coefficient of xy is 6</span>

The given pyramid's total surface area is 3. 24.0 square feet.
Step-by-step explanation:
Step 1:
To calculate the surface area of the given figure, we need to find the surface areas of the different shapes in the figure.
There are 3 triangles and 1 square in the figure.
Step 2:
All the triangles are similar.
The surface area of a triangle =
The similar triangles have a base length of 3 feet and a height of 2.5 feet.
The surface area of 1 similar triangle = square feet.
The surface area for all the similar triangles = square feet.
Step 3:
The surface area of a square is the square of its side length. The square has a side length of 3 feet.
The surface area of the square = square feet.
Step 4:
To calculate the total surface area we sum up all the individual surface area.
The total surface area = square feet which is the third option.
