Answer: S=25N
Step-by-step explanation:It is given that for every cup of sugar, the cookie company is able to make 25 cookies. Therefore the equation should begin with S, the total number of cups of sugar, and relate that to the number of cookies made. So, the correct answer would be for S (The total number of cups of sugar used) equals 25 times N (Number of cookies made.)
To find the length of the 3rd side, you would use the pythagorean theorem
a^2 + b^2 = c^2
132^2 + b^2 = 157^2
17424 + b^2 = 24649
b^2 = 7225
b = square root of 7225
<span>D. It is incorrect because the length of the unknown side is the square root of 7,225.</span>
Answer:
< 4, - 7 >
Step-by-step explanation:
- w - z
= - < - 5, 3 > - < 1, 4 > ← multiply each component in w by - 1
= < 5, - 3 > - < 1, 4 > ← subtract corresponding components
= < 5 - 1, - 3 - 4 >
= < 4, - 7 >
