5(x - 6) = 4x + 8....distribute thru the parenthesis
5x - 30 = 4x + 8
5x - 4x = 8 + 30
x = 38 <==
140 + 140 + 95 + 95 = 470 feet
Hope this helps!

Answer:
2 cm.
Step-by-step explanation:
It is given that the area of a square sports arena is 10,000 m².
Area of a square = Square of side.
Let side of square sports arena is x m.

Taking square root on both sides, we get


Side length of a sports arena cannot be negative. So x=100 m.
It is given that each centimeter in map represents 50 m.
50 m = 1 cm
Multiply both sides by 2.
100 m = 2 cm
Therefore, the dimensions of the sports arena on the map is 2 cm.
Answer:
-14 - 11i
Step-by-step explanation:
You may be learning about the imaginary number, i. Even though i is actually the squareroot of -1, when you are doing algebra with it, it acts just like a variable does. The special thing to remember about i is that i^2 is -1. But we don't even need that right now for this problem.
(-14 + 3i) - (14i)
= -14 + 3i - 14i
Combine the i's
= -14 - 11i
That's it. The -14 is the a, and the -11 is the b in a+bi.
If necessary to fill in a computer answer that is already formatted with a plus, like:
_ + _i
then use -14 for a and -11 for b.
