Answer: 5 and 4
Step-by-step explanation:
Perimeter = 2 ( L + W)
18 = 2(L + W) divide through by 2
9 = L + W
9 - L = W
Area = L * W
20 = L (9 - L)
20 = 9L - L^2
L^2 - 9L + 20 = 0 factor
(L - 5) (L - 4) = 0
Set both factors to 0 and solve for L
L = 5 and L = 4
Answer:
Step-by-step explanation:
The tip is $6.21
with that being said, 34.50 + 6.21 = 40.71
the total cost is $40.71
Answer: y= 3x - 
Step-by-step explanation:
Since we know the slope and a set of coordinates we can insert them into the formula y=mx+b and find what b is.
y=mx+b
-1/2=3(2)+b
-1/2=6+b
-1/2-6=6-6+b
-6 1/2=b
Therefore the equation is y=3x -
Answer:
61
Step-by-step explanation:
straight line = 180 degree
to find the measure of angle QPR,
subtract 119 from 180
=> 180-119
=> 61
angle QPR = 61 degree
