<h2>727</h2>
Step-by-step explanation:
Let us denote the three digit number by 
, where 
is the hundreds digit, 
is the tens digit and

Combine your like terms: 5v + 5 = 5v +4
subtract the 5v and 4 from each side: 0 = 1
because 0
1, there is no solution
X=2.
Area for a triangle is .5(bh)
.5(5(2))*12=200.
The length of the enlarged copy in feet is 2.7 feet.
<u>Step-by-step explanation</u>:
- The painting is 4 inches wide and 2 feet long.
- convert inches into feet (1 inch=0.083 foot). Therefore, 4 inches=0.3 feet
- The enlarged copy is 1 foot wide and 'x' feet long.
The width is enlarged from 0.3 to 1 which is increased by 0.7 feet.
∴ The length should also be increased by 0.7 feet = 2+0.7 = 2.7 feet
