Answer: y - 9 = 2(x - 5)
Step-by-step explanation:
Point slope form: y - y1 = m(x - x1)
substitute 5 for x1 and 9 for y1 and 2 for m
x1 = 5
y1 = 9
m = 2
you get y - 9 = 2(x - 5)
Answer:
4th is correct answer. 1, 2, 3 not correct you can check the exponents properties
(x+4)(x+4+1) = (x+1)(x+1+11)
(x+4)(x+5) = (x+1)(x+12)
x^2 + 4x+5x+20=x^2+x+12x+12
9x + 20 = 13x + 12
13x-9x = 20-12
4x = 8
x = 2
The diagram shows that all the sides of the rectangle are congruent. Since the perimeter all of the sides added up, all you have to do is divide the perimeter by 4.
Therefore, the perimeter, which is 16x + 24, can be divided by 4 to find the length of one side.
16x + 24/4 = length of one side. So, the length of one side is 4x + 6.

The 30:60:90 proportion is 1:sqrt 3: 2
So,
x = 10/2
x = 5
y = 10/sqrt 3
Finding the area:
1/2 * 5 * 10/sqrt 3
25/sqrt 3
Hope this helps!
