When I add or subtract polynomials, the degree adding
together too?
Ex: 5X^3-2X^2+7X^2, the degree staying 3 or 2? Or we add them?
Answer:
5X^3-2X^2+7X^2
5 x ^3 + 5 x^2
Adding polynomials: simply add the like terms together. Like
terms are terms with the same variables and exponents.
<span>
Subtracting polynomials: reverse the sign of each term
(in other words turn "+" into "-", and "-" into
"+"), then proceed to addition.</span>
Do not add the exponents.
Answer:
step by step:
3x+5=-2
move constant to the right-hand side and change it's sign
3x=-2-5
Calculate the difference
3x=-7
Divided both sides of the equation by 3

9
Step-by-step explanation:
For each pizza variety, Daniel can choose 18 different toppings. Therefore, for 23 pizza varieties, Daniel can choose from 23 * 18 = 414 different combinations of varieties and toppings.
For each pizza size, Daniel can choose from 414 different combinations of varieties and toppings. Therefore, for n pizza sizes, Daniel can choose from n * 414 = 3726 combinations
414n = 3726
divide both sides by 414 to isolate the n
n = 9
