Answer:
72 / 5
Step-by-step explanation:
( 12 / 5 ) + ( 6 / 5 )
= ( 12 + 6 ) / 5
= 18 / 5
[ ( 12 / 5 ) + ( 6 / 5 ) ] / ( 1 / 4 )
= ( 18 / 5 ) / ( 1 / 4 )
= ( 18 x 4 ) / 5
= 72 / 5
Answer: to find y, simply make the equation y+82=180 since we know a straight line is 180 degrees. Solving gives us Y=98.
To find Z we can use the vertical angles property. Y is equal to 4z+14 in this property. Since we know y=98, we can say that 4z+14=98. Let’s solve again. We get Z=21.
Step-by-step explanation: AGAIN, please ask me if this doesn’t make sense. I’ll try my best to explain further. Merry christmas lkwkn

To divide one fraction by another, invert (turn upside-down) the second fraction, then multiply.
Elimination would be the best way to answer this question because you can multiply the top by 3 and the bottom by -4
1 rational solution
4x² + 12x + 9 = 0
(2x+3)²=0
2x + 3 =0
2x +3 -3 = 0-3
2x = -3
2x/x = -3/2
x = -3/2
