Answer:
49n² - 70n + 25
Step-by-step explanation:
Area of a square = s²
Where,
s = side length = 7n - 5
Area of the square = (7n - 5)²
= (7n - 5)(7n - 5)
= 7n(7n - 5) -5(7n - 5)
= 49n² - 35n - 35n + 25 (distributive property of equality)
Add like terms
Area = 49n² - 70n + 25
The measurement of angle b is 128°
Which is an example of discrete data?
A) number of taxis waiting at the airport
B) volume of water in a glass
C) speed of a boat
D) weight of fish
Answer:
60°
Step-by-step explanation:
sum of interior angles of quadrilateral is 360°
∠C = 70°
∠D = 50°
∠C + ∠D = 120°
∴ ∠A + ∠B = 360° - 120° =240°
AO and BO bisect ∠A and ∠B
∠OAB + ∠OBA = 1/2 x ( ∠A + ∠B) = 120°
∠AOB = 180° - (∠OAB + ∠OBA) = 180° - 120° = 60°
50 divided by 8 = 6.25
1oz perfume = $6.25
110 divided by 17 = 6.4705
1oz perfume = $6.4705
Therefore the second option is cheaper
