Answer:

19\frac{11}{15}

Step-by-step explanation:

We have the problem:

6\frac{2}{3} *2+3\frac{1}{5} *2

6 2/3 can be written as (6 + 2/3), and 3 1/5 can be written as (3 + 1/5). So, we can then use the distributive property:

(6+2/3)*2+(3+1/5)*2=12+4/3+6+2/5=18+4/3+2/5

Now, we need to combine the fractions by finding a common denominator. Here, the common denominator is 3 * 5 = 15: 4/3 +2/5=20/15+6/15=26/15=1\frac{11}{15}

Finally, we add 18 to 1 11/15: 18+1\frac{11}{15} =19\frac{11}{15}

Thus, the answer is 19\frac{11}{15}.

Hope this helps!

What is the constant of variation for the quadratic variation?
Lorico [155]
Given:
x  =   2     3     4      5     6
y  = 20 ; 45 ; 80; 125;180

The constant variation for the quadratic variation is 5.

y = 5x²
y = 5(2²) = 5(4) = 20
y = 5(3²) = 5(9) = 45
y = 5(4²) = 5(16) = 80
y = 5(5²) = 5(25) = 125
y = 5(6²) = 5(36) = 180

How to factor 4x^2+24x+27​
fomenos

Answer:

(2 x + 3) (2 x + 9)

Step-by-step explanation:

Factor the following:

4 x^2 + 24 x + 27

Factor the quadratic 4 x^2 + 24 x + 27. The coefficient of x^2 is 4 and the constant term is 27. The product of 4 and 27 is 108. The factors of 108 which sum to 24 are 6 and 18. So 4 x^2 + 24 x + 27 = 4 x^2 + 18 x + 6 x + 27 = 9 (2 x + 3) + 2 x (2 x + 3):

9 (2 x + 3) + 2 x (2 x + 3)

Factor 2 x + 3 from 9 (2 x + 3) + 2 x (2 x + 3):

Answer: (2 x + 3) (2 x + 9)
