Step-by-step explanation:
12+3y+2=0
=14+3y=0
=3y=0-14
=3y=-14
=y=-14/3, -4 2/3
Well use the distributive property
-98=4x-2(5x+13)
Now multiply 2 times 5x+13
-98=4x-10x-26
Now combine like terms
-98=-6x-26
Now get 26 on the other side by adding it to -98
-6x=-72
x=12
Answer:
3
Step-by-step explanation:
16 and 12 because 16-12=4 and 16+12=28
10+8+6=24
π x 12/2
6 π
24+6 π= 42.84955592
