6 0

Answer:

x = -3        x=2

Step-by-step explanation:

x^2 + x - 6 = 0

Factor

What two numbers multiply to -6 and add to 1

3*-2 =-6

3+-2 =1

(x+3) (x-2) = 0

Using the zero product property

x+3 = 0   x-2 = 0

x = -3        x=2

Find the sum: 4 radical 3 + 11 radical 12
Ksenya-84 [330]

Answer:

26\sqrt{3}

Step-by-step explanation:

We want to find 4\sqrt{3} +11\sqrt{12}. 11\sqrt{12} can be written as 11\sqrt{4*3}=11*\sqrt{4} *\sqrt{3}=11*2*\sqrt{3}=22\sqrt{3}, so we can now write our original equation as: 4\sqrt{3}+22\sqrt{3}.

We can combine like terms: 4\sqrt{3}+22\sqrt{3}=26\sqrt{3}

Hope this helps!

A retailer incurs a fixed cost of N$ 500 when purchasing sugar for his stock. He pays N$ 10.00 per packet which he resells at N$
Arada [10]

Answer:

100 packets

Step-by-step explanation:

Given :

Cost = fixed cost + variable cost

Fixed cost = $500

Variable cost = $10

Sales price = $15

Let :

Number of packets = x

To break even :

fixed cost + variable cost = sales made

500 + 10x = 15x

500 = 15x - 10x

500 = 5x

x = 500 / 5

x = 100

100 packets
