Answer:
127.3 ft
Step-by-step explanation:
Our triangle has legs 90, 90, x. This is a special triangle when the hypotenuse is just one of the legs times the 
, thus 90. This is rounded to 127.3. Please mark as brainlienst.
First of all, lets define rational numbers....
A rational number is any number that can be turned into a fractions...it can be both positive and negative numbers. It also includes 0. Rational numbers are not always whole numbers.
Therefore, ur answer is : All the points on the graph could represent rational numbers
First square both sides
1-3x=(x+3)^2 use foil to unfactor it
1-3x=x^2+6x+9 subtract 1 from both sides
-3x=x^2+6x+8 add 3x to both sides
0=x^2+9x+8
Now that we got it equal to zero you have to factor the new trinomial
0=(x+1)(x+8)
Now since both are being multiplied by each other, if you get 1 of them to equal zero then both equal zero since 0 times anything equals 0.
So your solutions are x=-8 and x=-1
