A)f(4)=6(4)-9=24-9=15
B)f(1/2)=6(1/2)-9=3-9= -6
Answer:
SA=2lw+2lh+2hw
Step-by-step explanation:
Surface area is the sum of the areas of all faces (or surfaces) on a 3D shape. We can also label the length (l), width (w), and height (h) of the prism and use the formula, SA=2lw+2lh+2hw, to find the surface area.

Answer:
Rational numbers are fractional numbers, whose numerator and denominator are integers and the denominator is ever zero.
Step-by-step explanation:
The sum of rational numbers gives a rational number;
+
=
, because the evaluation of the denominator always results to a non-zero integer.
The product of
x
=
, which multiply both numerator and denominator to give integer numbers.
The sum and product of rational and irrational numbers are always irrational numbers, for instance,
x 7 = 2.3 , which is a number which decimal points that can only be represented by the product irrational number and rational number , where 7 is an irrational number.
+ 7 = 7
, which is a whole number and fractional number combined.
