Answer:
1 picture
answer is 60=8x-4 (alternate angle)now find x
2 picture
answer is 21x+6+90 =180(linear pair)
3 pictue
answer is 20x+5+24x-1=180 (co interior angle )
now solve equation and find out answer of if again problem ask me ...
Answer:
1.2262943855309168262595...
Step-by-step explanation:
You use the change of base formula:
![log_b(a) = \frac{log_c(a)}{log_c(b)}](https://tex.z-dn.net/?f=log_b%28a%29%20%3D%20%5Cfrac%7Blog_c%28a%29%7D%7Blog_c%28b%29%7D)
So in essence, you can take any base c and just divide by the log of the original base b.
A special base is e, which gives you the natural log ln.
So even ln 9 / ln 6 gives the same answer.
wow what even is that lol
Answer:
hit the square
Step-by-step explanation:
I'm pretty sure you have to hit the square and then that would be number two
5x^2+2x-3=0
We can use the quadratic formula:
ax^2+bx+c=0; a=5, b=2, c=-3
x=[-b+-sqrt(b^2-4ac)]/(2a)
x=[-(2)+-sqrt((2)^2-4(5)(-3))]/[2(5)]
x=[-2+-sqrt(4+60)]/10
x=[-2+-sqrt(64)]/10
x=(-2+-8)/10
Two solutions:
x1=(-2-8)/10→x1=(-10)/10→x1=-1
x2=(-2+8)/10→x2=6/10→x2=3/5
Answer: x=-1 and x=3/5
Answer: Options D. x=-1 and F. x=3/5
