In this proble, we are asked to determine the roots of the quadratic equation x^2 + 11 x = -24. The standard form is x^2 + 11 x + 24 = 0. the second term is the negative sum of the roots and the third terms is the equal to the product of the roots.Hence the roots should be -3 and -8.
Answer:
Answer:
A. Esmeralda converted the mixed number to the wrong improper fraction.
D. Esmeralda did not divide –24 by 6 correctly.
E. Esmeralda did not use the reciprocal of the divisor.
Answer:
D
Step-by-step explanation:
so total travel by x bikers = 50 multiplied by x = 50x
According to the question
50x = 560
dividing 560 miles by 50 miles per biker give ya 11.2 or approximately 12 bikers.
28=12+x
28 represents how tall he will get, 12 represents how tall he is in inches, and x is how much he still has left to grow! Hope it helps!
-10 = -10 + 7m
Add 10 to each side: 0 = 7m
Divide each side by 7 : 0 = m
Please take a second and just LOOK at the equation you started with.
It says:
-- You have this number '-10' .
-- Your number -10 is going to be exactly the same size
after you add 7 of something to it.
The ONLY way that could happen is if the 'something' is 'nothing' .
' m ' must be nothing.
