Answer:
x=6
Step-by-step explanation:
2(3x+4)=5x+3x-4
combine all like terms and distribute
6x+8=8x-4
-8 -8
6x= 8x-12
-8x -8x
-2x= -12
x= 6
Answer:
5
Step-by-step explanation:
-5 - (-10)
Here we have to use sign of multiplication rule.
negative * negative = positive
that is, -(-) = +
We use this rule and simplify.
- (-10) = + 10
Therefore, -5 + 10
When we have different sign of the numbers, we have to subtract from greatest to least number, then put the largest number sign in the answer.
-5 + 10 = + 5
Hence, the answer is 5
Hope this is will help you.
Thank you.

Step-by-step explanation:
A=2πrh+2πr2
Answer:
SUM OF ALL ANGLES OF A TRIANGLE =180
THEREFORE,
X+8+2X-3+6X-5=180
9X=180
X=20.
THEREFORE,<J=X+8=20+8=28
<K=6X-5=6*20-5=120-5=115
<L=2X-3=2*20-3=40-3=37.
