<u>Answer:</u>
The correct answer option is b. Darius will get the better deal buying one 16 ounce bottle.
<u>Step-by-step explanation:</u>
We know that a 16 ounce bottle of the salad dressing is for $3.36 while a 10 ounce bottle is priced at $2.30.
Darius has a coupon for 40 cents off if he buys two 10 ounce bottles. We are to determine what is the better buy.
Price of one 16 ounce bottle = $3.36
Price of two 10 ounce bottles = (2.30 × 2) - 0.4 = $4.2
Therefore, Darius will get the better deal buying one 16 ounce bottle.
Answer:
i believe its C
Step-by-step explanation:
Note that c is the hypotenuse of the blue triangle, and that the Pyth. Thm. states that (length of one leg)^2 + (length of the other leg)^2 = (hyp)^2.
Therefore, (hyp)^2 = c^2 = [2sqrt(x^2+3x)]^2 + 3^2, or
= 4(x^2+3x) + 9, or
= 4x^2 + 12x + 9 = (2x+3)^2
Taking the sqrt of both sides, c = plus or minus (2x+3). Eliminate -(2x+3) because the middle term of the square of this would be negative, in conflict with the given +12x.
c=2x+3 is the correct answer.
Compare two variables each time
Y = x^2 + 8x - 3
y = x^2 + 8x + (8/2)^2 - 3 - (8/2)^2
y = x^2 + 8x + 16 - 3 - 16
