The diagram below shows an equilateral triangle ABC with AB = (4x - 9)cm. Diagram not drawn to scale
В B.
Α'
(4x – 9) cm
The perimeter of the triangle is 45 cm.
Calculate the value of x.
[3]
+

x=17

step-by-step explanation:

solve 3x-24=x+10

then that makes it 2x=34 because you subtract an x from both sides to get rid of the one on the right, and then you add 24 to both sides to get rid of the 24 on the left

divide by both sides by 2 to get your answer so that you can get your answer

you didn't post any answer choices, so its not 100% clear what your teacher is looking for

however, log(15/7) is equivalent to log(15) - log(7)

i'm using the rule log(x/y) = log(x) - log(y)

i agree because i see the other persons thinking is clear
