In simplifying polynomials, we need to remember
that only like terms can be added or subtracted to each other. Also, the order
of solving the basic operators should be followed which is PEMDAS.
<span>3x2y2 − 5xy2 − 3x2y2 + 2x2
The first and the thrid term is equal to zero thus the polynomial is:
</span>− 5xy2 <span>+ 2x2
</span>
The polynomial has two terms with a degree of three.
Let's start by seeing what percentage is incorrect.
100-85=15
So, 15% is incorrect when answering 3 problems wrong. So let's divide 15 by 3.
15÷3=5
So, each problem is worth 5%, let's divide 100 by 5. The reason I'm doing thiis is to find how many questions are on the quiz, since if you got them all right, it's 100.
100÷5
20
There are 20 questions, let's make sure this is correct.
If she got 3 wrong, she got 17 right. Let's calculate her percentage and make sure it is the right one.
17÷20
.85×100
85%
So, there are 20 questions on the math quiz.
Answer:
that equals 0.0801
Step-by-step explanation:
but im not good at rounding so yeah
Answer:
$ 2250
Step-by-step explanation:
3375 = s³
s = ∛3375
s = 15 ft.
floor area = s² = (15 * 15)
floor area = 225 ft²
the contractor charges $10 per ft².
therefore,
the hardwood cost = 225 x $10 = $2250
