2x + (x+9) = 90
3x + 9= 90
3x= 81
x= 27
Now plug in 27 to (x+9)
27+9= 36
Final Answer = 36

Answer: if the width was not effected then the width is still 24 inches
if the area stayed the same, then
find area
area=legnth times width
288=12 times 24
so the new height./legnth =2
288=2 times width
divide by 2
144=width'
the new width =144

Answer:
xº=71º
Step-by-step explanation:
Take the triangle BDH
Once the sum of interior angles of a triangle is 180º:
40º+31º+yº=180º
71º+yº=180º
yº=109º
Once yº and xº are supplementary angles (add up to 180º):
yº+xº=180º
109º+xº=180º
xº=71º
