Answer:
x=12
Step-by-step explanation:
since they are similar triangle .Use these ratios
9/6=x+9/14
do cross multiplication
6(x+9)=14*9
6x+54=126
6x=126-54
x=72/6
x=12
Answer:
length is 60 and width is 30
Step-by-step explanation:
because the formula to find perimeter is 2l+2w and if you plug 60 and 30 into that equation then you get 120+60 which is 180
8x + y = 12 (substitute 3 for y)
<span>8x + 3 = 12 </span>
<span>8x = 9 </span>
<span>x = 9/8 </span>
<span>If y = 3 and 8x + y = 12, then x = 9/8.
HOPE THIS HELPS!!</span>
