The answer is: "12 feet" .
________________________________
Note: In a square, the length of EACH of the four sides of the square is the same.
Area = Length * width.
For a square, length = width.
So for a square, Area = length * width = (length of a side)² = s² ,
Given: A = s² = 144 ft² ;
Solve for the positive value of "s" .
________________________________
→ s² = 144 ft² ; Take the "square root" of each side ;
→ √(s²) = √(144 ft²) ;
→ s = 12 ft.

The answer is: 12 ft.

Answer:
1) -66
2)
Step-by-step explanation:
Given:
a=4
b=-5
c=-7
=a+2bc
=4+2*-5*7
=4+(-10*7)
=4-70
=-66
=3a
=3(4)
=12
Hope this helps ;) ❤❤❤
Answer:
seems to easy to be true but the answer is 7/12 cause it's a fraction and it can't be simplified
Answer:
(4,12)
(-1,-3)
Step-by-step explanation:
x^2 - y = 4
y = 3x
Use substitution. Substitute 3x for y in the first equation
x^2 - (3x) = 4
x^2 -3x =4
Subtract 4 from each side
x^2 -3x -4 = 4-4
x^2 -3x-4 =0
Factor
(x-4) (x+1) =0
Using the zero product property
x-4 =0 x+1 =0
x=4 x=-1
Now to find y for each x solution
x=4
y =3x = 3(4) =12
(4,12)
x=-1
y =3x = 3(-1) =-3
(-1,-3)
