Answer:
1/5
Step-by-step explanation:
Equation: 
Points: (-3, -9) and (22, -4)
is the second y point that shows up on the question, basically go by order. So it's -4
is -9, because again, in order of which coordinates pop-up first in the question
is 22, 
is -3
Now input into the equation, to make it easier we'll split the fraction into 2 equations:
= 
and 
, we'll put them back in a fraction later
= -4 - (-9) = -4 + 9 = 5
= 22 - (-3) = 22 + 3 = 25
now put it in the fraction, remember y on top x on the bottom:
5/25, simplify, 1/5
Answer:
(1) P=4a+4
(2) P=2a+4
a
Step-by-step explanation:
Well, let us call longer side b, shorter side a and diagonal d. The perimeter of a rectangle is 2*(a+b). Let us write this formula as P=2*(a+b)
In (1) it is stated that b=a+2. Hence, the perimeter of the rectangle is P=2*(a+b). In terms of b, let us write (a+2). So P=2*(a+a+2)=4a+4.
In (2) it is stated that d/a=13 or d=13a. From Pythagorean theorem d^2=a^2+b^2. Hence, b^2=168a^2 or b=2a. Finally, P=2*(a+b)=2*(a+2a)=2a+4a

Answer:
79
Step-by-step explanation:
equation:
18x - 8 + 11x = 20x +19
Add like terms:
29x - 8 = 20x + 19
add 8 to both sides:
29x = 20x + 27
subtract 20x from btoh side:
9x = 27
Divide both sides by 9:
x = 3
substitute x into the equation for SU
SU = 20(3) + 19
Solve:
SU = 79
