Simplify

Solve for x

SOLUTION:
Perimeter = 2(3x+x)
Also Perimer = 20
therfore;

2(4x)=20
Divide Both sides by 2

4x=10
2x=5
x=5/2

x= 2.5cm

Find x, given that the perimeter of the rectangle is 20cm

SOLUTION:
3(X-3)=30
Divide Both Sides by 3

(X-3)=30/3=10

X-3=10

Collect like terms

X=10+3

X=13

Solve for x
SOLUTION:
Hint: employ vertically opposite angles rule and angles on a straight line rules. Also consider the rule of a right angled-triangle

Therefore, 100+30+x=180 (final sum of angles on the footed horizontal straight line)

130+x=180
x=180-130
x=50

THIS SOLUTION IS AWESOME
