Common denominator is 7*4 = 28. We start with 77/28 and give 12/28 away. That leaves us with 65/28, or 2 and 9/28. IF your question was about what's left, this is what's left.
4/9 is smaller
I rounded and simplified.
Answer:
The length is x + 5 inches
When x = 14, the width is 12 inches and the length is 19 inches.
The polynomial is x² - x - 12.

Answer:
0.9938
Step-by-step explanation:
Let mean blood pressure be = x
Pr ( x < 119 ) can be found using ' z value ' = ( x - u ) ÷ ( s / √n ) ; where x = 119 , u = mean = 117 , n = no. of sample items = 144 , s = standard deviation = 9.6
z = (119 - 117) ÷ (9.6 / 144) = -2 ÷ (9.6 / 12) = -2 / 0.8 → z = 2.5
Pr (x < 119) = P (z < 2.5)
P = 0.9938
