Answer:
1. trapezoid
A quadrilateral with at least one pair of parallel sides.
2. bases of a trapezoid
The parallel sides
3. legs of a trapezoid
The nonparallel sides.
4. median of a trapezoid
The segment connecting the midpoints of the legs.
5. isosceles trapezoid
A trapezoid with legs of the same length.
y+z=10
x+z=8
x+y=12
(y+z)-(x+z)=10-8
y-x=2
y-x=2
y+x=12
solve simultaneously
x=5, y=7
then substitute to get z=3
hence xyz=573
Answer: C) 3
Explanation:
The degree of a single variable polynomial is the largest exponent, which in this case is 3.
The last two.
They are equivalent
3+3=6 6•4=24
4•3=12 12+12 is 24
To move tot he right h units, subtract h from every x
to move up k units, add k to the whole equaiton
added 1 to every x (subtract -1)
added6 to whole thing
moved -1 to right (moved 1 to left)
moved up 6 units
answer is A
