Determine the product of (x+11)(x-7)

x² + 4x - 77

Step-by-step explanation:

To find the product, use the FOIL method. FOIL = First, Outside, Inside, Last.

(x + 11)(x - 7)

First:

(x)(x) = x²

Outside:

(x)(-7) = -7x

Inside:

(11)(x) = 11x

Last:

(11)(-7) = -77

Remember to simplify by combining like terms:

x² - 7x + 11x - 77

x² (-7x + 11x) - 77

x² + 4x - 77

x² + 4x - 77 is your answer.

the ratio of white tiles to blue tiles is 48: 16. the ratio in it's simplest form is 3: 1.

step-by-step explanation:

ratio: take the first number and add a colon next to it, then add the second number after that. make sure the ratio order matches up with the written problem!

simplest form: we can simplify the ratio 48 : 16 by dividing both terms by the greatest common factor (gcf).

the gcf of 48 and 16 is 16.

divide both terms by 16:

48 ÷ 16 = 3

16 ÷ 16 = 1

reducing to simplest form:

48 : 16 = 3 : 1
