You can solve all of these by using the distance formula. I have shared it below.
Answer:
The GCF should be 9
Step-by-step explanation:
Answer:
(6 - 5x(2))(x(4) - x(3))
(6 - 5x^2) (x^4 - x^3)
6x^4 - 6x^3 - 5x^6 + 5x^5
-5x^6 + 5x^5 + 6x^4 - 6x^3
Step-by-step explanation:
Answer:
x=28
Step-by-step explanation:
We can use similar triangles and proportions to solve this problem. Put the side of the small triangle over the same side of the larger triangle.
x 42
---------- = ----------
x+10 42+15
Simplify
x 42
---------- = ----------
x+10 57
Using cross products
57x = 42 (x+10)
Distribute
57x = 42x+420
Subtract 42x from each side
57x-42x = 42x-42x +420
15x = 420
Divide each side by 15
15x/15 = 420/15
x=28
