Answer:

\frac{12}{63} \: and \:  \frac{14}{63}

Step-by-step explanation:

The lowest common multiple between 21 and 9 is 63 as 21 = 21, 42, 63

9 = 9, 18, 27, 36, 45, 54, 63

therefore the common denominator is 63

\frac{4}{21}  =  \frac{?}{63}

21 × 3 = 63, so do the same to the numerator.

4 × 3 = 12 the numerator is 12

\frac{4}{12}  =  \frac{12}{63}

let's do the same to 2/9

\frac{2}{9}  =  \frac{?}{63}

9 × 7 = 63, so do the same to the numerator.

2 × 7 = 14

the numerator is 14

\frac{2}{9}  =  \frac{14}{63}

The answer is 4 because if area is 28 meaning when you times the base and the height you'll get 28 therefore if you plug in 4 in the spot of x it should be 4+3 which equals 7 and since the value of x is 4 on top it must be 4 on the side too so you must do 7×4 which equals 28

The solution of the given quadratic equation is x=-2 or x=-3.

The given quadratic equation is x²+5x+6=0.

<h3>What are different methods to solve a quadratic equation?</h3>

The different methods of solving quadratic equations are factoring, completing the square or using the quadratic formula.

By using the splitting middle term method we can solve x²+5x+6=0.

That is, x²+2x+3x+6=0

⇒x(x+2)+3(x+2)=0

⇒(x+2)(x+3)=0

⇒(x+2)=0, (x+3)=0

⇒x=-2 or x=-3.

Therefore, the solution of the given quadratic equation is x=-2 or x=-3.

Marianna [84]
This problem's quiet easy!

Cost for Members = $10 (x)
Cost for Non-Members = $ 24 (y)

2(x)+4(y) = Total Value. 
2(10)+4(24) = Total Value
20+96 = Total Value

Total Value = $ 116.
