AlexFokin [52]3 years ago
3 0

Answer:

The result for this equation is \frac{8}{9}n - \frac{4}{3} .

Step-by-step explanation:

-Solve:

\frac{4}{9} (2n-3)

-Multiply 2n and -3 by \frac{4}{9} :

\frac{8}{9} + \frac{-12}{9}

-Reduce \frac{-12}{9} to the lowest term by extracting and canceling out 3:

\frac{8}{9}n - \frac{4}{3}

-So, the result is \frac{8}{9}n - \frac{4}{3} .

If the perimeter of a square is 20, what is the length of the diagonal ?
Rina8888 [55]

Answer:

Step-by-step explanation:

if you know that the perimeter is 20,

then you have to divide by 4 to get the length of one side

20/4=5.

Draw the diagonal and write in it's length as x.

Use Pythagorean formula

Then know that a2+b2=c2

and use the two side lengths as a and b.

This gives you the equation

5^2+5^2=x^2.

Do the calculations and solve the equation.

25+25=x^2

50=x^2

√50=x.

Therefore x=√50 where x equals the length of the diagonal.

Beatruce = B

Andrew = B+2

Andrew is 36   (34+2)

Chris is 31 (34-3)

36+31 = 67
