Step-by-step explanation: Take your initial value times the percent of your discount to find the discount amount: in this case, it is 300 * .10 = 30. Then you can subtract that value from your initial value, 300-30=270 to get the sale price.

Which expression is equivalent to (x+2)(3x-3)

navik [9.2K]

Answer:

$3x^2+3x-6$

Step-by-step explanation:

$\left(x+2\right)\left(3x-3\right)$

Use FOIL.

$x\cdot \:3x+x\left(-3\right)+2\cdot \:3x+2\left(-3\right)$

$3xx-3x+2\cdot \:3x-2\cdot \:3$

$3x^2-3x+2\cdot \:3x-2\cdot \:3$

$3x^2-3x+6x-6$

$3x^2+3x-6$

Using the formula C = 2πr, find the circumference of a circle with diameter of 28 inches. Round your answer to the nearest inch.

Stolb23 [73]

The formula given to us relates circumference with radius but we are given diameter instead. good thing we know that diameter is twice the length of radius so if diameter=28, the radius=14. therefore, using our formula, we can find the circumference:
C = 2(pi)(14)
C = 87.96
and this answer is close to 88 so the answer is A

let me know if you have any questions!!!
