Answer:

the factored equation is ((x^3) +  3x^2) +  2x  = 0

Step-by-step explanation:

*The ^ means to the power of.

so you should start off by splitting it into ways, like isolate 2x and start with x^3 and 3x^2, if thats the wrong answer u are not looking for then the other formula is x^3 + 3x^2 + 2x  =   x • (x^2 + 3x + 2), again just splitting it into ways. since we know the equation is = to 0, we put 2 of them together, and since you can divide everything by x and just put x outside to keep it the same, it would become x^3 + 3x^2 + 2x  =   x • (x^2 + 3x + 2).

Pls help me solve this ​
sammy [17]

Answer:

4 kg of sugar would contain 1.2 \times 10^9 crystals.

Step-by-step explanation:

Given that 3kg of sugar contains 9 × 10⁸ crystals, let "x" represent the number of sugar crystals 4kg of sugar would contain.

Thus, set up a proportion as follows:

3 kg : 9 × 10⁸ = 4 kg : x

\frac{3}{9 \times 10^8} = \frac{4}{x}

Solve for x. Cross multiply.

3 \times x = 9 \times 10^8 \times 4

3x = 36 \times 10^8

3x = 3.6 \times 10^9

Divide both sides by 3

\frac{3x}{3} = \frac{3.6 \times 10^9}{3}

x = 1.2 \times 10^9

4 kg of sugar would contain 1.2 \times 10^9 crystals.

Answer:

150 for lower seats and 200 for higher seats

Step-by-step explanation:

Need two equations and then solve using substitution method:

Equation 1 for tickets sold:

$35x + $25y = $10,250

Equation 2 for quantity (number #) of tickets sold:

x + y = 350

Use substitution method:

y = 350 - x

35x + 25 (350 - x) = $10,250

35x + $8750 - 25x = $10,250

10x + $8750 = $10,250

        - $8,750       -$8,750

10x = 1,500

x = 150

 

y = 350 - 150

y = 200

Check the answers:

$35 (150) + $25 (200) =

$5,250 + $5,000 = $10,250
