Cancel out the denominators.
(x+5)² + 18 = -30
(x+5)² = -30 - 18
(x+5)² = -48
The equation is impossible, we have a negative number.
There isn't a number that squared gives a negative number (the square is always positive).
√(x+5)² = +/- √-48
x+5 = +/- √-48
IMPOSSIBLE
You can write the result in imaginary numbers
x+5=+/- 4i√3
Denise is the fastest runner. 40 divided by 6 is 6.666 repeating 30 divided by 5 is 6 and 20 divided by 4 is 5 therefore denise is fastest
It would be c, and here is why:
x is the difference between original and final amounts of food, aka the amount eaten by the hamster. Find difference with subtraction, initial minus final=difference. 2.1-1.3=0.8
x=0.8
<span> x from -6 to 5, y from -10 to 10, y = -2x/3 -2). </span>
<span>Average speed = distance over time so here
Speed = (22 1/2) / (1/3) = 67 1/2 miles per hour</span>
