Answer:
Brett is 62 years old, Carl is 70 years old and Mark is 80 years old.
Step-by-step explanation:
let the age of Brett be <em>x</em> years.
thus the age of Mark is <em>(x+18)</em> years .
{as it is given that Brett is 18 years younger than Mark}
∴ Age of Carl is <em>(x+8) </em>years .
Now the sum of ages,
3x+26=212 (given)
3x=186
∴x=62
thus , the age of Brett is 62 years , the age of mark is <em>(x+18)</em>= 80 years and the age of Carl is <em>(x+8)</em>= 70 years
I have an answer and an explanation!

1) First table
x2-x1=6-3→x2-x1=3
y2-y1=1920-1960→y2-y1=-40
x3-x2=9-6→x3-x2=3=x2-x1
y3-y2=1900-1920→y3-y2=-20 different to y2-y1=-40. The table does not represent a linear relationship.
2) Second table
x2-x1=7-5→x2-x1=2
y2-y1=1860-1900→y2-y1=-40
x3-x2=9-7→x3-x2=2=x2-x1
y3-y2=1820-1860→y3-y2=-40=y2-y1
x4-x3=11-9→x4-x3=2=x3-x2
y4-y3=1780-1820→y4-y3=-40=y3-y2
x5-x4=13-11→x5-x4=2=x4-x3
y5-y4=1740-1780→y5-y4=-40=y4-y3
The table represents a linear relationship.
3) Third table
x2-x1=2-1→x2-x1=1
y2-y1=1000-2000→y2-y1=-1000
x3-x2=3-2→x3-x2=1=x2-x1
y3-y2=500-1000→y3-y2=-500 different to y2-y1=-1000. The table does not represent a linear relationship.
4) Fourth table
x2-x1=6-4→x2-x1=2
y2-y1=1640-1840→y2-y1=-200
x3-x2=8-6→x3-x2=2=x2-x1
y3-y2=1360-1640→y3-y2=-280 different to y2-y1=-200. The table does not represent a linear relationship.

sorry other one I don't know
Answer:
181.044m²
Step-by-step explanation:
First, work of the surface area of the base (bottom rectangle area)
Formula : base × height
6×2=12m²
Formula : LW+L
For the 8.8 bit i got 83.734 (sorry i can't be asked right now to put down all my working out)
and for the 9 i got 85.31
add them all together we get 181.044
