Answer:
-12°
Step-by-step explanation:
it is negative because it it below zero.
Answer:
e) 20
Step-by-step explanation:
Segment lengths:
|(2, 7) -> (8, 7)| = |(8-2, 7-7)| = |(6, 0)| = 6
|(8, 7) -? (8, 11)| = |(8-8, 11-7)| = |(0, 4)| = 4
because we know it's a rectangle, we can infer that the other two sides also have lengths 4 and 6, so the perimeter is 4+4+6+6=20
The GCF of 20x^4 and 6x^3 would be " 2x^3 "
We know that area of the square is 141 square feet. Therefore, we can figure out the dimension of square using formula for area as shown below:

We know that fencing is used along the sides of the square. Therefore, amount of fencing required will be equal to perimeter of square.
Hence, we can write:


Upon rounding to nearest foot, we get the amount of fencing required as 48 feet.
