Answer:
The length of a spring varies directly with the mass of an object that is attached to it. When a 30-gram object is attached, the spring stretches 9 centimeters.
Step-by-step explanation:
X^a times X^b = X^a + b
so 4x times 6x = 24x^(1+1)
2(5x + 2)
2.3 2.389 2.39 2.4 2.41
2.3<2.389 (2,39)<2.39<2.4<2.41
an equivalent expression is...
-4x+3
