B: -8
8 times 1 = 8, and since there is a negative in front of the 1 when you are multiplying, it should be -8/
The greatest common factor is 2
This is because we start by taking the largest factor that goes into both coefficients. Since the first coefficient is 2, we have to try 2 and 1. Since 2 is larger and goes into 36 evenly, we use that.
Then we use the smallest number of each variable. There are 4 r's in both equations. So, that is the number that we take. There are 2 s's in the first term, so we take that number.
Answer: 25
Assuming the dotted line touches the middle of the base of the triangle,
Using Pythagoras Theorem,
(30/2)^2 + (20)^2 = x^2
x^2 = (15)^2 + 400
x^2 = 625
x = √625 or -(√625)
x = 25 or -25
But since x needs to be a positive value,
x = 25
D. Translation and dilation, no
You know it’s a translation because first it’s not in the same spot and second it is an answer choice in all the answer
You know it’s not a reflection because the shape looks the same and every point faces the same direction
So that is means it’s a dilation.
You also know that it’s a dilation because there is a size difference between the two.
Lastly because of the size difference, they aren’t congruent because congruent means the same and they aren’t the same size
Answer:
r < -504
Step-by-step explanation:
The problem says;
72 + r < -432
Inverse operations;
72 + r < -432
-72 -72
r < - 504
