Answer:
Greater than the actual product because both numbers where rounded up to the closest tenth.
Step-by-step explanation:
37 x 86 - original
40 x 90 - rounded
37 < 40 - greater than
86 < 90 - greater than
Checking --->
37 x 86 = 3182
40 x 90 = 3600
3182 < 3600
Given:
Length = 3x + 6y cm
Area = 3x² + 9xy + 6y²
Because Area = Width * Length, therefore
Width = Area/Length
= (3x² + 9xy + 6y²)/(3x + 6y).
Width =


Answer:
x+y
Try this explanation:
this is quadratic function (parabola, common view of equation is y=ax²+bx+c).
Domain: The function exists in all the points. It means, that x∈R or x∈(-oo;+oo).
Range: according to the common view a>0, it means, that parabola has 'min' in its vertice (x₀=-1). Range is y∈[4;+oo) or y≥4.
