Answer:
-2 < AC < 8
Step-by-step explanation:
The last side has to be less than the sum of the other 2 sides, or less than 8. The only answer choice with this is the 3rd one.
8a + 14
=>8a = -14
=>a = -14/8
=>a = -7/4
so i think its
at the bottom: 6 x 7 = 42
sides: 5 x 7 x 2 = 70
triangles : 2 x 1 / 2 x 6 x 4 = 24
42+70+24 equals to 136!! hope u understand ^^
Answer: i'm pretty sure the answer is C
y=3x+9......(i)
y=-4x-12...(ii)
these are the equation
