Can you please ask someone else
<span>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 5x<span>4 </span>+ 3x<span>3 </span>– 6x<span>2 </span>+ 2x containing one variable<span>, </span>but polynomials can also contain multiple variables. An example of a polynomial with two variables is 4x2y – 2xy2 + x – 7.</span>
Many formulas are polynomials <span>with more than one variable, such as the formula for the surface area of a rectangular prism: 2<span>ab </span>+ 2bc + 2ac, where <span>a, b, </span>and <span>c </span>are the lengths of the three sides. By substituting in the values of the lengths, you can determine the value of the surface area. </span>By applying the same principles for polynomials with one variable, you can evaluate or combine like terms in polynomials with more than one variable<span>.</span>
Answer:
It's (B) Rhombus and (D) Rectangle
Step-by-step explanation:
Answer:
-3=x
Step-by-step explanation:
subtract 4 from both sides so -2x=6 then divide by -2 so x=-3
