Answer:
24
Step-by-step explanation:
Let d represent Donald's age now. Then Natali's age now is d+38. The age relationship 5 years ago was ...
(d+38) -5 = 3(d -5)
d +33 = 3d -15 . . . . . eliminate parentheses
48 = 2d . . . . . . . . . . . add 15-d
24 = d . . . . . . . . . . . . . divide by 2
Donald is 24 years old now.
_____
<em>Alternate solution</em>
You can also work this by considering that 5 years ago, Natalie's age was more than Donald's age by twice Donald's age then. Hence Donald was 38/2 = 19 at that time. Now, Donald is 19+5 = 24.
In order to find the solution by graphing we need to make two equation with x and y terms
we use Left hand side 4x^2 for first equation and right side x^2 -7 for second equation.
So the equation becomes
first equation 
Second equation 
are the system of equations that can be graphed to find solution
Answer:
the answer is 50cm
Step-by-step explanation:
x=5
so 5+5 would be 10
so the long side would be 10 and the short side would be 5
so 5cmx10cm= 50cm
