Answer:
(2 × 7 × 13) / (7 × 11) =
((2 × 7 × 13) ÷ 7) / ((7 × 11) ÷ 7) =
(2 × 7 ÷ 7 × 13)/(7 ÷ 7 × 11) =
(2 × 1 × 13)/(1 × 11) =
(2 × 13)/11 =
26/11;
Step-by-step explanation:
Answer:
a. 0
Step-by-step explanation:
1. To find the slope given two points, use the following formula:
2. 
would be the second y-value (in the second ordered pair), 2, and 
would be the first y-value (in the first ordered pair), also 2.
3. Same for the x-values. 
is -2 and 
is 4
4. Now plug in the values.
5. This equals 
which simplifies to 0
Answer:
L = 20 inches
Step-by-step explanation:
w = width
L = length
area = 120
W x L = 120
L - 8 = 2W then L = 2W + 8
substitute for L:
W x (2W + 8) = 120
2W² + 8W -120 = 0
(2W - 12)(W + 10) = 0
2W-12 = 0
2W = 12
W = 6
L = 20
