(x+7)(x+9) <br>Do this math problem by using the Foil method.​
Setler79 [48]
Foil:
First term
Outer term
Inner term
Last term

By using foil we just times the first terms together so: x*x=x^2

Then we times the outer terms together so: x*9=9x

Then we times the inner terms together so:7*x=7x

Finally we times the last terms together so: 7*9=63

So our equation is:
X^2+9x+7x+63

Now we collect the like terms

Answer: x^2+16x+63

Hope this helped

Find the degree of the polynomial<br> 2x^4y^2+9x^2y^5-3x^4y^4
coldgirl [10]

Answer:

the polynomial has degree 8

Step-by-step explanation:

Recall that the degree of a polynomial is given by the degree of its leading term (the term with largest degree). Recall as well that the degree of a term is the maximum number of variables that appear in it.

So, let's examine each of the terms in the given polynomial, and count the number of variables they contain to find their individual degrees. then pick the one with maximum degree, and that its degree would give the actual degree of the entire polynomial.

1) term  2\,x^4\,y^2  contains four variables "x" and two variables "y", so a total of six. Then its degree is: 6

2) term  9\,x^2\,y^5  contains two variables "x" and five variables "y", so a total of seven. Then its degree is: 7

3) term  -3\,x^4\,y^4  contains four variables "x" and four variables "y", so a total of eight. Then its degree is: 8

This last term is therefore the leading term of the polynomial (the term with largest degree) and the one that gives the degree to the entire polynomial.
