I don't know how you expand it but the answer is 3x + 25 unless that's expanding.
A). because B,C, and D didnt really make any sence
Answer:
Step-by-step explanation:
The diagonals of the given parallelogram are QS and RT. We would first determine if its diagonals are congruent.
QS = √(1 - 5)² + (3 - 3)² = 16
RT = √(3 - 3)² + (4 - 2)² = 4
Since QS ≠ RT, it means that they are not congruent and this means that the parallelogram is not a rectangle.
Let us check if the diagonals are perpendicular.
Slope of QS = (3 - 3)/(5 - 1) = 0/4
Slope of RT = (2 - 4)/(3 - 3) = - 2/0
The slopes are not opposite reciprocals. It means that the diagonals are not perpendicular. Therefore, the correct option is
D. QRST is none of these because its diagonals are neither congruent nor perpendicular.
Answer:
x = 19 , y = 54
Step-by-step explanation:
- 3x+5 and 6x-14 are linear pair angles, they add up to 180
- So angle 3x + 5 = 3 (19) + 5 = 62 degrees
- angle 62 and angle y+8 are corresponding angles, so they are equal
