We know, Perimeter of a rectangle = 2(l + w)
2(6+x+2) = 2(3+2x+1)
2(8+x) = 2(4+2x)
16+2x = 8+4x
16-8 = 4x - 2x
8 = 2x
x = 4
Unknown lengths, x+2 = 4+2 = 6
2x+1 = 2(4)+1 = 8+1 = 9
2) We know, Area of a rectangle = a * b
2[7(x+1)] = 4(3x+6)
2[7x+7] = 12x+24
14x+14 = 12x+24
14x-12x = 24-14
2x = 10
x = 5
Lengths of unknown sides, x+1 = 5+1 = 6 cm
3x+6 = 3(5)+6 = 15+6 = 21 cm
Hope this helps!
The answer is No solution
- Evaluate [5 - (5 - 5(2 - 5) + 2)] + 6
![\sf [5 - (5 - 5(2 - 5) + 2)] + 6](https://tex.z-dn.net/?f=%20%20%5Csf%20%5B5%20-%20%285%20-%205%282%20-%205%29%20%2B%202%29%5D%20%2B%206)
Subtract 5 from 2 to get -3.
Multiply 5 and -3 to get -15.
The opposite of -15 is 15.
Add 5 and 15 to get 20.
Add 20 and 2 to get 22.
Subtract 22 from 5 to get -17.
Add -17 and 6 to get -11.
You add the previous 2 numbers so the answer would be 162
