The partial tactonization of x - 3x - 10 is modeled with algebra tiles which unit tiles are needed to complete the factorization? 2 negative unit tiles 2 positive unit tiles 5 negative unit tiles 5 positive unit tiles

(x+2)(x-5)

Step-by-step explanation:

If it is a quadratic equation as I think it is, else there is no sense, it's possible to see that we need two numbers in such a way its multiplication is -10 and its sum -3 . The only two natural numbers are +2 and -5, therefore the correct factorization is (x+2)(x-5).

c.

step-by-step explanation:

she should of added 9^2 and 12^2. that is because it is a^2+b^2=c^2. c^2 is the hypotenuse and should always be bigger than the other two numbers. which is why she should of added 9 squared and 12 squared together instead of 15 squared.
