Answer:
Two systems of equations are equivalent if they have the same solution(s).
Answer:
3*5^6
Step-by-step explanation:
Using distributive property, we get:
3x-9=0
3x=9
x=3
So, x=3. Now that was easy, huh? :)
7x9=63
63÷2= 31.5x4
126= area of the triangles
7x7= 49= area of the square.
126+49= 175 ft
1000 is the answer! hoped I helped
