The TV to have a 16:9 ratio and have a diagonal of 65 inches must have a length & width whose squares add to 4,225 (65 squared) and whose ratio length and width simplifies to 16/9.

B is not an option because $16^2+9^2\neq 65^2$ .

C is not an option because $\frac{42.59}{21.22}\neq \frac{16}{9}$ which is 1.777777777778 as a decimal.

D fails for the same reason as C.

Therefore A is the solution because $\frac{56.65}{31.86}=\frac{16}{9}$ and $65.65^2+31.86^2 = 65^2$

Both 7 and 13 are factors of 1001. Explain how to use this information to get two other factors.

Answer:

Step-by-step explanation:

"Factors" are the numbers you multiply to get another number. For instance, factors of 15 are 3 and 5, because 3×5 = 15. Some numbers have more than one factorization (more than one way of being factored). For instance, 12 can be factored as 1×12, 2×6, or 3×4.
