Charlotte's family bought a 2-pound block of cheese. There is 1/4 of the block left. How many ounces of cheese has Charlotte's family eaten?help
Answers
1 pound is 16 ounces, so 2 would be 32 ounces. 1/4 is left, divide 32 by 4 you get 8. 8 ounces is left

X squared minus 18x minus 144 equals 0. Solve by factoring.
Answers
x^2 - 18x - 144 = 0
Factorise: We choose 2 numbers that add to -18, and multiply to 144, these numbers are +6 and -24, we put it into the brackets:
(x + 6)(x - 24) <- x = the interted sign of the numbers inside the brackets
E.g. +6 turns into -6 and -24 turns into +24
x must = -6 or = +24
Answer got deleted because I have to explain it better, which I will kindly do. (x^2 - 18x - 144) = 0 What two factors add up to equal -18 AND multiply to equal -144? For a product to be a negative, one of the factors have to be a positive, and the other has to be a negative (positive times a negative equals a negative). And now that we know that, we know that the negative number has to be larger than the positive because of the -18. What two factors add up to equal -18 AND multiply to equal -144? Negative 24 and positive 6. (x - 24)(x + 6)
