Answer:
x = 4
Explanation:
For the right hand side:
log base 9 of 8 + log base 9 of (x-2) = log base 9 (8*(x-2))
= log base 9 of (8x-16)
For the left hand side:
2*log base 9 of x = log base 9 of x^2
Now, equating the two sides and solving for x:
log base 9 of (8x-16) = log base 9 of x^2
This means that:
x^2 = 8x - 16
x^2 - 8x + 16 = 0
(x-4)^2 = 0
Therefore:
x = 4
Hope this helps :)
Answer:
72
Step-by-step explanation:
6(5+7)
6(12)
72
GCF is 6
Use the distributive property by factoring out 6, like I did above
B ============> - 1
C ============> Multiply 5
E =======> Multiply 2
F ======> Multiply 1 / 2
Hope that helps!!!!! : )
There is a mistake in your writing
:The similar triangles should be ABE (& not ABD as you stated) & ACD
If so, we can write the following proportion:
AB/AC = BE/CD.
We know that AB =10, BE=4, AC= 10 + BC (BC =12, Given), so AC =22
Plug into the above: 10/22 =4/y===> y= (22 x 4)/10===> y =44/5 =8.8
Answer:
x = 24
Step-by-step explanation:
x = .4(60)
x = 24
