Answer:
5
Step-by-step explanation:
AC=AB+BC
so 16=x+1+x+7
which simplifies to 16=2x+8
subtract eight from both sides to get 8=2x
then divide by 2 to get that x=4
AB=x+1, which substitutes into 4+1=5
Answer:
1. The top and bottom lines (-5,3) (8,3) is parallel to line (-2,-2) (11,-2). The sides Lines (-5,3) (-2,-2) is parallel to line (8,3) (11,-2).
2. None of the line create a right angle. None are able to create a box at the angle
Answer:
11x² - y
Step-by-step explanation:
Step 1: Write out expression
10x² - y + x²
Step 2: Combine like terms
11x² - y
That is simplest form.
The answer is negative 80 or like this -80
