Given: y²+5y
Converting y²+5y in the form: x²+2ax+a²
Here 2a=5 or a=5/2
Add and subtract (5/2)²
y²+5y+(5/2)²-(5/2)²
Complete the square.
(y+5/2)²-(5/2)²
Simplify
(y+5/2)² - 25/4
Answer: (y+5/2)² - 25/4
Answer:
Step-by-step explanation:
1) the triangle is right, so we can use the Pythagorean theorem
x^2 + 24^2 = (16+x)^2
x^2 + 576 = x^2 + 256 + 32x
32x = 320
x = 10
2) the two segment are congruent, so
7x - 13 = 9x - 23
2x = 10
x = 5
Answer:
8!

Answer:
1470 students do not have a full-time or part-time job
Step-by-step explanation:
We have a relationship between students who have a part-time job and those who do not. The ratio is 7 out of 10 students.
Then we use this relationship as a conversion factor.
If of 10 students, 7 of them have a job, then of 4900 students, how many of them have a job?
students
Finally, those who do not have a job are:
