Answer:
Step-by-step explanation:
The first equation is
The second equation is
When we graph these two equations, <em>they will meet at a point which represent the solution of the two equations</em>.
We can solve the two equations simultaneously to determine their point of intersection.
Let us substitute the second equation into the first equation to get;
Multiply through by 2 to get;
Group similar terms to obtain;
Simplify;
Divide both sides by 3;
Put into the second equation;
Therefore the graphs of the two functions intersect at (2,3)
See graph in attachment.
The formula for the area of a square is:
A=s²
Since we known that the area is 81ft², we can solve for the length of a side.
A=s²
81=s²
find the square root of both sides
9ft=s
The length of each side is 9ft

Answer:
Gabby= 172.5 Jase= 137.5
Step-by-step explanation:
310-35= 275
275/2= 137.5 = Jase add 35 for Gabby
137.5+35=172.5
