y² - 7y + 6
y = -3
<u>Step 2: Evaluate</u>
- Substitute in <em>y</em>: (-3)² - 7(-3) + 6
- Exponent: 9 - 7(-3) + 6
- Multiply: 9 + 21 + 6
- Add: 30 + 6

Answer:
c = 12.5
Step-by-step explanation:
This is a right triangle so we can use the Pythagorean theorem (a^2 + b^2 = c^2)
lets say 10 = a and 7.5 = b (this is because they are the legs of the triangle and variables a and b represent the legs of the triangle)
plug into the Pythagorean theorem.
10^2 + 7.5^2 = c^2
simplify (here you just square 10 and 7.5)
100 + 56.25 = c^2
simplify
156.25 = c^2
simplify
(here you get the square root of 156.25 and c^2, the positive square root of 156.25 is 12.5 and the square root of c^2 is c)
12.5 = c

Answer:
a. Tim has completed a greater amount of work.
b. Together they have completed
part of two projects.
Step-by-step explanation:
Let us assume that the project on which Jaime and Tim are working has x amount of space.
Now, given that Jaime has 5 over 11 space of a project completed while Tim has finished 7 over 13 space of the same project.
Therefore, Jaime has completed
amount of space and Tim has finished
amount of space.
a. Now, (7x) \times 11 > (5x) \times 13
⇒
Therefore, Tim has completed the greater amount of work. (Answer)
b. Together they have completed
amount of space out of 2x amount of space. (Answer)
