Answer:
25
Step-by-step explanation:
because there are vertical angles
B
they will be congruent if there is a pair of parallel lines
Answer:
R: (16, 2)
Step-by-step explanation:
Let (x, y) be the point R
(x - 10)/2 = 3 and (y + 12)/2 = 7
x - 10 = 6 y + 12 = 14
x = 16 y = 2
R: (16, 2)
Answer:
x=8
Step-by-step explanation:
The ratio of a side of PQRS to the corresponding side in TUVW. is 6:4=3:2.
The ratio of RS:VW=3:2. RS=12, and VW=x. 12:x=3:2. 3 multiplied by 4 is 12, so 2 multiplied by 4 is x. So, the makes x=8.
Answer:
x = 4 ± 
Step-by-step explanation:
Given
x² - 8x = 3
To complete the square
add ( half the coefficient of the x- term )² to both sides
x² + 2(- 4)x + 16 = 3 + 16
(x - 4)² = 19 ( take the square root of both sides )
x - 4 = ±
( add 4 to both sides )
x = 4 ±
