Answer:
x=12
Step-by-step explanation:
oPQ= 15 and ST= x-3 and segment PQ and segment ST are congrunt so 15-3=12 and that makes x 12
The common denominator would be 15 since 5 times 3=15.
Answer:

Step-by-step explanation:
An expression means that we don't know enough to create an equation. So, this means we will mostly be using variables.
John runs r amount every day. We need to create an expression for if he runs r amount for 4 days.

r = how much he runs per day
4 = how many days he runs
z = how much he runs this week
This is your expression!
Answer:
(x^2-6)^2
Step-by-step explanation:
slope m = –4
equation
y - 3 = -4(x + 2)
y - 3 = -4x - 8
y = -4x - 5 where slope = -4 and y intercept = b = -5
Answer
Y intercept (0, -5)
