The answer should be D: Zero.
A triangle has three sides. Two of them are called the legs and the last longest one is called the hypotenuse. You have to do this equation:
l^2 + L^2 = h^2
The sum of the legs to the power of 2 should equal the hypotenuse to the power of 2
7(7) + 2(2) = 10(10)
49 + 4 = 100. This is false. So you cannot make a triangle with these three side lengths.

Well, if you say it's A...  But that does make sense.  Using the triangle inequality theorem, there is only one triangle you can make from that.

Find the difference of(ab+8a+1)-(-6ab+4)
vagabundo [1.1K]
Hey there!

When finding the difference of expressions like these, there's a few things you should keep in mind. 

1. When finding the difference of two polynomials, multiply the polynomial that implied to be "negative" by –1 to expand the problem and make it easier to solve. 

2. You combine terms based on their unknown terms, like x, y, x², ab, etc. You cannot combine the terms x and x², but you can combine the terms 6b and 8b by adding them. 

3. You can rearrange your terms however you see fit. If a polynomial is implied as "positive", you can multiply that entire polynomial by +1 to get rid of the parentheses. 

With all that in mind, you can go ahead and solve for your difference, like so:

(ab+8a+1)-(-6ab+4)

(ab+8a+1) (-1(-6ab+4))

(ab+8a+1) + (6ab-4)

ab+6ab+8a+1-4

7ab+8a-3

7ab+8a-3 will be your difference. 

Hope this helped you out! :-)

9

Step-by-step explanation:

if you mean -3.2x+9 then the answer is 9 because you plug in 0 into x and solve the equation, you get the x intercept
