Answer:
x=5/12
Step-by-step explanation:
Simplify left side by adding 11x+x
12x+5=10
Get x alone on left side by subtracting 5 on both sides
12x=5
Get X alone by dividing both sides by 12
x=5/12
No. An irration number is a fraction, thats a decimal
First find the area of the triangle,
(8.4 x 24)/2 = 100.8
Then find the area of the parallelogram,
24 x 12 = 288
Then add both,
100.8+288 = 388.8 yd^2
