Devaughn is 9 years younger than Sydney. The sum of their ages is 83 . What is Sydney's age?

Vesna [10]

D:devaughn
S:sydney

D+S=83. First equation
D=S-9. Second equation
D-S=-9

Add 2 equations

D+S+D-S=83-9
2D=74
D=37

Devaughn is 37 years old
So

D+S=83
37+S=83
S=46

Sydney is 46 years old

Answer:

The answer to your question is: 83 + 6 $\sqrt{35}$

Step-by-step explanation:

This is a square of a binomial.

(2 $\sqrt{5}$ + 3 $\sqrt{7} )^{2}$

1.- Square of the first term

( 2 $\sqrt{5} )^{2}$ = 4(5) = 20

2.- Twice the product of the two terms

(2)(2 $\sqrt{5} )$ (3 $\sqrt{7} )$ = 6 $\sqrt{35}$

3.- Square of the second term

(3 $\sqrt{7)})^{2}$ = 9(7) = 63

4.- Write the solution

20 + 6 $\sqrt{35}$ + 63

83 + 6 $\sqrt{35}$
