Answer:
C. x=12
Step-by-step explanation:
The answer is D, because that is what you should get when you multiply it out.
4x^2 times x^2 = 4x^4 because...
1) multiply the 4 and the one in front of the x on the second term = 4 then
2) multiply x^2 times x^2 to get x^4, not x^3, so you can immediately eliminate A and B to save time.
Now let's deal with the second part..."may or may not be" part
A polynomial is an expression with more than two algebraic terms
terms are like...
2x + 3y ---there's two terms there, eventhough the 2 and x are multiplied, it doesn't count (same with the 3 and y)
since it only have two terms, not more than two terms, it is called a binomial, not polynomial. I think that's what they mean by that
one term with a variable (y,x,and so on) is called a monomial
one term with no var is called a constant
there's many more but hope this gave you some help
10*2/5= 20/5 = 4 = 4.0 where 4 is the unit.(whole number)
First you are using the pothagorean theorem which is a^2+b^2=c^2. You have a and b, so you should plug them in to get 4^2+4^2=c^2. Then simplify it some more to 16+16=c^2. Now finish simplifying to c^2=32. Now take the square root of each side and you have your answer. So your answer will be c=√32 or c is about 5.66.
