Answer:
3√7
Step-by-step explanation:
√63
√3x21
√3x3x7
3√7
64/1×5/8=320/8. 320÷8=40. There is 40 gallons of gas in the truck
So first we factor
9-t^2=difference of 2 perfect squares
a^2-b^2=(a-b)(a+b)
3^2-t^2=(3-t)(3+t)
t^2+t-12
factor by finding what 2 number add to get 1 and multiply to get -12
the numbers are -3 and 4
(t-3)(t+4)
[(3-t)(3+t)]/[(t-3)(t+4)] we can't factor out any further
if it was t^2-9 then we could go further but since it isn't this is the factored form
(<u><em>if</em></u> it was t^-9 then the answer would be (t+3)/(t+4))
Starting at the origin means starting at (0,0)/ moving left 5 units means x will be -5, and moving up 2 units mean y will equal 2.
(-5,2)
