Answer:
no solution
Step-by-step explanation:
2+2x=19+2x
2x-2x=19-2
0=17
The answer to that is 0.80 which is f because you convert the answer like you would do normal equations
Answer:
x=9, x=-9
Step-by-step explanation:
subtract 3 from both sides
x^2=81
then squareroot both sides (remember that there is a positive and negative solution!)
x=9, x=-9
Perimeter is the sum of all sides of a polygon. For this case, the perimeter is expressed as: P=a+b+c. It has been said that the longest side is twice that of the shortest side. Let's assume that a is the longest side and b is the shortest side. So, the equation for the shortest side is,
6.2 = 2c
c = 3.1
14.5 = 6.2 + 3.1 + b
<span>14.5 = 9.3 +b</span>
