3. Kay’s mother taught her how to make handmade ornaments to sell at a craft fair. Kay rented a table at the fair for $50 and set up her work station. Each ornament that she makes costs approximately $3.50 for materials. She sells each ornament for $7. a. If x represents the number of ornaments sold at the craft fair, which of the following expressions would represent Kay’s profit? (Select all choices that apply.)

7x-50

-50+7x-3.50x

7x-50-3.50x

3.50x-50

4.50x-50

the 1st digit is in the 100s n its 1

step-by-step explanation:

3,589÷18 = 199.389

so the first digit of the quotient is in the 100s n its 1

answer is 8x+24

area of vanessa's patio = length × width

given, length = (3x² + 5x + 10)

width = (x² - 3x - 1)

area of vanessa's patio = (3x² + 5x + 10)(x² - 3x - 1)

= 3x²(x² - 3x - 1) + 5x(x² - 3x - 1) + 10(x² - 3x - 1)

= 3x⁴ - 9x³ - 3x² + 5x³ - 15x² - 5x + 10x² - 30x - 10

= 3x⁴ - 4x³ - 8x² - 35x - 10

hence, expression of vanessa's patio = (3x⁴ - 4x³ - 8x² - 35x - 10)

answer: 0

step-by-step explanation: the positive, like 5, + its opposite, like -5 would be 0

5+(-5)=0, or 5-5=0
