Answer: A
a quadrilateral with all four angles right
Step-by-step explanation:
A quadrilateral is a rectangle if a quadrilateral has all four angles right,
a parallelogram with congruent sides
a quadrilateral with diagonals that are congruent and bisect each other
a quadrilateral with all congruent angles. Because a rectangle possesses 2 pairs of parallel sides, 4 right angles at 90°. It has opposite sides which
are parallel and congruent. And all its angles are congruent.
But a quadrilateral with all four angles right is a description that does NOT guarantee that a quadrilateral is a rectangle. Because this description is also applicable to a square.
Z² -<span> 6z - 27 = 0
</span>z² + 3z - 9z - 27 = 0
z(z+3) - 9(z+3) = 0
(z+3)(z-9) = 0
z + 3 = 0 or z - 9 = 0
z = -3 z = 9
Answer: z=-3 and z=9
It’s -7, not -3 because cd is 16 apart and 1/8 is 2 units to the right of c making it -7.
Let say
e=number of english teachers
m=number of math teachers
3 more english tahn math
e=m+3
ratio if e to m is 6:5
e:m=6:5
e/m=6/5
e=m+3
(m+3)/m=6/5
times 5m both sides
5(m+3)=6m
5m+15=6m
minus 5m both sides
15=m
e=m+3
e=15+3
e=18
