<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:
I think the answer is :
D.
Step-by-step explanation:
Answer:
6
Step-by-step explanation:
**6** (total) / **3** (a third) **=2** (how many eggs hatched)
Ok, so:
To do this problem, first, we assign variables.
Let x be the smaps that Many collected.
If Margie collegted 4 times as many stamps as Sam, Margie collected 4x stamps.
Then, we know that both of them have 210.
So x + 4x = 210.
Solving the equation:
5x = 210
And x = 42.
Many collected 42 stamps.
Now, we use the last fact to find how many stamps Margie collected.
Margie collected 4x stamps, that is 4(42), which is equal to 168 stamps.
Margie collected 168 stamps.
