Answer:
It's the first one.
Step-by-step explanation:
Collect like terms.
x-4+x^2-2x+3
---------------------------
x-7
take x and (-2x): this equals -x
Take (-4) and 3: this equals (-1)
reorder the terms
-x-1+x^2
------------
x-7
Use the commutative property
x^2-x-1
------------
x-7
A=bh/2=(19 x 11)/2=(209)/2=104.5 inches
The correct answer is choice C) 136.2.
Why is it C)? Because 264.72 - 128.49 = 136.23 and then round it to nearest tenth and u get 136.2.
