Answer:
4.2
Step-by-step explanation:
By intersecting chords theorem:
![x \times 10 = 6 \times 7 \\ \\ 10x = 42 \\ \\ x = \frac{42}{10} \\ \\ x = 4.2](https://tex.z-dn.net/?f=x%20%5Ctimes%2010%20%3D%206%20%5Ctimes%207%20%5C%5C%20%20%5C%5C%2010x%20%3D%2042%20%5C%5C%20%20%5C%5C%20x%20%3D%20%20%5Cfrac%7B42%7D%7B10%7D%20%20%5C%5C%20%20%20%5C%5C%20%20x%20%3D%204.2)
Answer:
A. 20
Step-by-step explanation:
- First we need find X.
- x = 7 (because we see question). f(g(7))
- Now we find g(x) = x - 3 => g(x) = 7 - 3
- Next we find f(x) = x² + x . We have f(4)
- f(4) = 4² + 4
- = 20
Answer:
I'm sorry I don't know the answer. But have you tried Photomath? it helps me so much! have a good day/night! ❤️
The multiply choice were worth 4 points.
Gretchen= 18x+19
Ezia= 15x+31
So basically you can enter any number. At first I picked 3 and then I did the math and I got 73 points for Gretchen and 76 points for Ezia.
Then I pick four and then I got 91 points for them both. This is how I got the answer:
18x+19=15x+31
18(4)+19=15(4)+31
72+19=60+31
91=91
