Answer:
x = -31/4
Step-by-step explanation:
3(2x+5) = 2(x-8)
or, 6x+15 = 2x-16
or, 6x-2x = -16-15
or, 4x = -31
or, x = -31/4
Answer:
8 units if it's talking about the shown triangle, and 4 units if it's talking about the original
Step-by-step explanation:
I would guess it's talking about the original so do 4 units first
Well, this answer is easy because.... n is an obtuse angle (more than 90 degrees) and there is only 1 answer that is more than 90 degrees.
So, the correct answer is D. 95°
In the first series, the summation applies to the whole (2n+3) inside
the parentheses, so the 3 gets summed up 5 times.
But in the second one, the summation only applies to the 2n , so
the 3 is only added after the summation is finished.
The difference between five 3s the first time and one 3 the second time
is your 12 .
