Answer:the percent of increase of sales at the car lot is 6%

Step-by-step explanation:

Number of cars sold last year is 600.

Number of pickups sold last year is 200.

This year, the number of cars increased by 12%. This means that the amount by which the number of cars that was sold this year increased would be

12/100 × 600 = 0.12 × 600 = 72

Therefore, the number of cars sold this year would be

600 + 72 = 672

This year, the number of the pickups sold decreased 12%. This means that the amount by which the number of pickups that was sold this year decreased would be

12/100 × 200 = 0.12 × 200 = 24

Therefore, the number of pickups sold this year would be

200 - 24 = 176

The total number of vehicles sold last year is 200 + 600 = 800

The total number of vehicles sold this year is 672 + 176 = 848

The amount by which the sales increased would be 848 - 800 = 48

Therefore, the percent of increase of sales at the car lot would be

48/800 × 100 = 6%

Which equation can be solved using the expression StartFraction negative 3 plus-or-minus StartRoot (3) squared + 4 (10) (2) EndR

katen-ka-za [31]

Answer: B. 2 = 3x + 10x2

Step-by-step explanation:

This is the concept of quadratic equations; We required to find the type of equation that can be solved using the model that has been used to solve the equation such that the answer is:

[-3+-sqrt(3^2+4(10)(2))]/(2(10))

The formual that was applied here was a quadratic formula given by:

x=[-b+\-sqrt(b^2-4ac)]/2a

whereby from the our substituted values above,

a=10,b=3 and c=-2

such that the quadratic equation will be:

10x^2+3x-2
