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

Answer:
48
Step-by-step explanation:
think of the a squared plus b squared equals c squared. plug in the 36 in either b or a. then plug in the 60 in c's spot. solve and get 48. you can check the answer by solving 48 squared plus 36 squared equals 60 squared. both sides are equal and both come out to be the 3600
Answer:
Volume = length× width× height
v=lwh
v=8×6×7
v=48×7
v= 336inches
Answer:
Roots are x=6 and - 4
Step-by-step explanation:
2(x-6)(x+4)=0
(x-6)=0 or (x+4)=0
x=6 or x=-4, their multiplicities is 1
