How do I factor this using foil (factoring trinomials)

(n - 10)(n-1)

Step-by-step explanation:

You have to choose two values that multiply to 10 and add to -11. Those to values are -10 and -1.

n² - 10n - 1n + 10

Rearrange them so that they can have a common factor.

n² - 1n - 10n + 10

1n (n - 1) + -10 (n + 1)

1n (n - 1) - 10 (n - 1)/ n-1

(n - 10)(n-1)

4sqrt5

step-by-step explanation:

the base has dimensions of 8 x 4, so the diagonal is 64 + 16 square rooted or 4sqrt5.
