200 miles. If their traveling 400 miles per hour. 30 minutes is half so u cut the miles in half
Given the quadratic function, to get the roots we factorize:
3x²-4x-7=0
3x²+3x-7x-7=0
3x(x+1)-7(x+1)=0
(3x-7)(x+1)=0
thus the roots are
x=-1 or x=3/7
thus the sum of the roots will be:
-1+3/7
=-4/7
Answer:
x^4
Step-by-step explanation:
all you have to do is add the exponents which is x^4
The first is a hexagonal prism
