Answer: a. x^3 - x^2 + x + 3
You have to expand the terms by multiplying them.
(x^2 - 2x + 3)(x + 1)
= x^3 + x^2 - 2x^2 - 2x + 3x + 3
= x^3 - x^2 + x + 3
10 minutes at 2 meters/second
1 minute = 60 seconds
10 minutes = 600 seconds.
600 seconds at 2 meters/second
2 meters × 600 = total distance
1200 meters <em>or</em> 1.2 km
Answer:
1) x = -2
Step-by-step explanation:
1) x + 7 + x + 11 = 14
2x + 18 = 14
2x = 14 - 18
2x = -4
x = -4/2 = -2
Answer:
The answer is "Option a".
Step-by-step explanation:
In the given scenario, The appropriate test for the teaching profession's accomplishment pre and post-class would be the two-sample t-test with dependent samples, that's why choice "a" is correct.
Answer:
Step-by-step explanation:
a^2 + b^2 = c^2
where
a and b are the legs
and
c is the hypotenuse
.
the problem gives the "legs" because the LONGEST leg is always the hypotenuse.
a^2 + b^2 = c^2
1071^2 + 1840^2 = c^2
1147041 + 3385600 = c^2
4532641 = c^2
