Answer:
378
Step-by-step explanation:
We know that she bought a television for $350 and the tax rate is 8%. This means the equation will be 350+(0.08*350). We can solve that equation using benchmark fractions since that's the quicker method of doing it.
To find 8% of 350, we can do 1% of 350 = 3.5 and we just multiply 3.5*8 which is 28. So we do 350+28.
You could also do 350*.08 but that's less efficent

Answer:
17x² - 22x - 2
Step-by-step explanation:
Given
(5x² + 6x - 2) + 4x(3x - 7) ← distribute parenthesis
= 5x² + 6x - 2 + 12x² - 28x ← collect like terms
= 17x² - 22x - 2
Answer:
Perry is correct, she covered the greatest area = 18 square units.
Step-by-step explanation:
Looking at the attached diagram, the shapes are rectangular and they are on grid or graph
Note that on a graph:
1 square box = 1 unit
Area of rectangle = Length × Width
For Karina
The Width = 3 units
The length = 4 units
The area which Karina covered = 3 units × 5 units
= 15 square units
For Perry
The Width = 9 units
The length = 2 units
The area perry covered = 9 units × 2 units
= 18 square units
Therefore, Perry is correct, she covered the greatest area = 18 square units.
