He chose the incorrect sign for the sum.
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
To find out how much Marie will save you have to multiply the 20% with the original praise which is $40.00. So we’ll change the 20% to 0.20 to multiply it with 40.
0.20 x 40 = 8
So Marie will save $8.00 using the coupon
F the fraction is greater than 1, in other words the numerator is greater than the denominator, the product will be greater than the whole number.If the fraction is less than one, in other words the numerator is less than the denominator, the product will be less than the whole number.If the fraction is equal to 1, in other words the numerator is equal to the denominator, the product will equal the whole number.
