Vertical angles are where the top equals the bottom or the left equals the right angle. So we would do:
8x - 13 = 5x + 8
And then substitute.
3x = 21
x = 7
<span>Simplify 3ab + 4ab + 5
= 7ab + 5 (combine like terms)

Answer:
log₃(2z²)
Step-by-step explanation:
2(log₃8 + log₃z) - log₃(3⁴ - 7²)
= 2[log₃(2³) + log₃z] - log₃(81 - 49)
= 2(3log₃2 + log₃z) - log₃(32)
= 6log₃2 + 2log₃z - log₃(2⁵)
= 6log₃2 + 2log₃z - 5log₃2
= log₃2 + log₃(z²)
= log₃(2z²)
15/14 or 1 1/14
Just change 2/7 to 4/14 and add.
You would minus 5 by 45 giving you 40 then 40 divided by 35 but that would come out as a decimal 1.14.
is this all of the question?
