1. Round 24 to 20 and 15 to 20. 20*20=400. True product is 360.
2. Round 37 to 40 and 63 to 60. 40*60 is 2400. True product is 2331.
3. Round 384 to 380 and 45 to 50. 380*50=19000. True product is 17280
C is the circumcenter of the triangle
So PC =RC = QC
Plug in
3x + 7 = 5x - 15
-2x = - 22
x = 11
Applying algebra, we can conclude that: Jerry sent 40 messages, and Kyle sent 25 messages.
Let's use algebra to solve this problem.
Let's represent the number of messages Ginger sent as "G," the number of messages Jerry sent as "J," and the number of messages Kyle sent as "K."
We are given the following information:
Ginger sent 18 text messages, so G = 18.
Jerry sent 4 more than twice as many messages as Ginger sent, so J = 2G + 4.
Kyle sent 15 fewer messages than Jerry, so K = J - 15.
Now, let's substitute the value of G from the first equation into the second equation to find the value of J:
J = 2 * 18 + 4
J = 36 + 4
J = 40
Now that we know Jerry sent 40 messages, we can find Kyle's number of messages using the third equation:
K = 40 - 15
K = 25
So, Jerry sent 40 messages, and Kyle sent 25 messages.

Answer:
288 \pi
Step-by-step explanation:
The value of b that makes x-2 a factor of x² - bx + b is 4.
Polynomial is an expression involving the operations of addition, subtraction, multiplication of variables.
Types of polynomials are quadratic, linear, cubic and so on.
The factor theorem states that; when f(k) = 0, then (x – k) is a factor of f(x).
Given that x-2 is a factor of x² - bx + b, hence:
f(2) = 2² - b(2) + b = 0
4 - 2b + b = 0
b = 4
Therefore the value of b that makes x-2 a factor of x² - bx + b is 4.
