Step-by-step explanation:
You have studied polynomials consisting of constants and/or variables combined by addition or subtraction. The variables may include exponents. The examples so far have been limited to expressions such as 5x4 + 3x3 – 6x2 + 2x containing one variable, but polynomials can also contain multiple variables. An example of a polynomial with two variables is 4x2y – 2xy2 + x – 7.
Many formulas are polynomials with more than one variable, such as the formula for the surface area of a rectangular prism: 2ab + 2bc + 2ac, where a, b, and c are the lengths of the three sides. By substituting in the values of the lengths, you can determine the value of the surface area. By applying the same principles for polynomials with one variable, you can evaluate or combine like terms in polynomials with more than one variable
Answer:
V =345 cm^3
Step-by-step explanation:
The volume of a cylinder is given by
V = Bh where B is the base and h is the height
V= 23 * 15
V =345 cm^3
Answer:
D
Step-by-step explanation:
it's 100% I'm super sure
3/8 of 16 = (16 / 8) x 3
= 2 x 3
= 6
2/3 of 6 = (6 / 3) x 2
= 2 x 2
= 4
