area of a square is S^2
103 = S^2
s = sqrt(103) = 10.14889
so length of side is approximately 10.15
12,800 is rounded to the nearest hundred
The total area of the pentagon should be 144 inches!!!
Were you trying to say n^2+7n+12? If so...
Answer: (n+4)(n+3)
Step by Step:
n^2+7n+12
n^2+4n+3n+12
n(n+4)+3(n+3)
(n+4)(n+3)
If not and you were trying to simplify... n2+7n+12
Answer: 9n+12
Answer:
0.4
step-by-step explanation
5x times 3 = 7 times 2x-4
first, you divide both sides by 2x
2.5x times 3 = 7-4
then, divide both sides by three
2.5x = 1
lastly, divide both sides by 2.5
x = 0.4
