Solve the quadratic formula

X^2-5x-14=0

Answers

Answer:

Step-by-step explanation:

Sum = -5

Product = -14

Factors = 2 , (-7)      because 2*(-7) = -14 and 2 + (-7) = -5

x²  - 5x - 14 = 0

x² + 2x - 7x - 14 = 0

x(x + 2) -7(x + 2) = 0

(x + 2)(x - 7) =0

x + 2 = 0           ;  x -7 =0

     x = -2  ;            x  = 7

Answer:

3) Reflexive Property

4) SAS

Step-by-step explanation:

ST ≅ TS

1. The Reflexive Property states that: a quantity is congruent (equal) to itself.

Example: a = a  In this case, it could be seen as ST ≅ ST because they have/are the same side(s).RST ≅ UTS

1. SAS theorem states that: two triangles are equal if two sides and the angle between those two sides are equal.

Example: RST ≅ UTS (both have S and T) Can be seen as RST ≅ UST as well to make their similarity more evident.

2. Because it is given that RS ≅ UT and RT ≅ US, and it includes the same 2 lines being equal as given/said, RST ≅ UTS because of SAS (theorem).

Would y^10/y^10 become 1?

Answers

Answer:

yes

Step-by-step explanation:

If you are dividing it will become 1 because 10 minus 10 equals 0. Anything to the power of 0 is 1 then you keep the base which is y so the answer is y

If you are multipling the answer will be y^10  because 10 plus 10 is 20 and you keep the base which is y
