Answer:
Step-by-step explanation:
A polynomial is the sum or difference of one or more monomials. A monomial is a constant, a variable, or the product of constants and variables. It does not include negative exponents.
The first choice is a polynomial because the only terms are variables with positive exponents and constants.
The second choice is a polynomial because the only terms are variables with positive exponents and constants.
The third choice is not a polynomial because the first term has a negative exponent.
The fourth choice is a polynomial because the only terms are variables with positive exponents and constants.
Answer:
You could use Math-way to help.
It asks you what kind of answer you want.
Step-by-step explanation:
You first put in the equation then you tell them you want it to be answered by long division. Then you'll get the answer.
Answer:
so the transitive property can be invoked in step 9
Step-by-step explanation:
Without the figure, it is difficult to tell what these steps do. However, the symmetry of the proof suggests that step 4 can match step 8, and its Reason can be "deduced from steps 2 and 3."
The idea of steps 4 and 8, taken together, is to show that DC and DB are both equal to DA, so the transitive property can be invoked in step 9.

Rearrange:
Rearrange the equation by subtracting what is to the right of the equal sign from both sides of the equation :
2*x^2-3*x-(2)=0
Step by step solution :<span>Step 1 :</span><span>Equation at the end of step 1 :</span><span> (2x2 - 3x) - 2 = 0
</span><span>Step 2 :</span>Trying to factor by splitting the middle term
<span> 2.1 </span> Factoring <span> 2x2-3x-2</span>
The first term is, <span> <span>2x2</span> </span> its coefficient is <span> 2 </span>.
The middle term is, <span> -3x </span> its coefficient is <span> -3 </span>.
The last term, "the constant", is <span> -2 </span>
Step-1 : Multiply the coefficient of the first term by the constant <span> <span> 2</span> • -2 = -4</span>
Step-2 : Find two factors of -4 whose sum equals the coefficient of the middle term, which is <span> -3 </span>.
<span> -4 + 1 = -3 That's it</span>
Step-3 : Rewrite the polynomial splitting the middle term using the two factors found in step 2 above, -4 and 1
<span>2x2 - 4x</span> + 1x - 2
Step-4 : Add up the first 2 terms, pulling out like factors :
2x • (x-2)
Add up the last 2 terms, pulling out common factors :
1 • (x-2)
Step-5 : Add up the four terms of step 4 :
(2x+1) • (x-2)
Which is the desired factorization
Half of 2/3 is:
This means that 1/3 was left. This also means that they ate 1/3 of the lasagne.
