A fraction is something like 1/2 which is the same as half of one or 1/4 which is a fourth of one
Answer:
The formula to find the speed(s) of an object is s = d/t (d-distance, t-time)
=> d = s x t
Frank drove his car at an average speed of 43 mph for 2.5 hours
=> the distance he drove: d = 43 x 2.5 =107.5 miles
Hope this helps!

Answer:
x = -2+√3i and -2-√3i
Step-by-step explanation:
The formula for the general formula is expressed as;
x = -b±√b²-4ac/2a
Given the expression
x²+4x+7 = 0
a = 1, b = 4 and c = 7
Substitute
x = -4±√4²-4(1)(7)/2(1)
x = -4±√16-28/2
x = -4±√-12/2
x = -4±√4*-3/2
x = -4±2√-3/2
x = -4±2√3i/2
x = -4+2√3i/2 and -4-2√3/2
x = -2+√3i and -2-√3i
