Step-by-step explanation:
Answer:
Semicircle = 
semicircle = 
semicircle = 51.4
∴ the perimeter is 14 + 32 + 51.4
∴ The perimeter is 97.4 cm
Area 1 = 
Area 1 = 20 ÷ 2 = 10
Area 1 = 
Area 1 = 314.2
Area 2 = 14 × 32 = 448
Area = Area 1 + Area 2
Area = 762.2cm²

Step-by-step explanation:
Answer:
(4x + 7) or
(16x^2 - 28x + 49)
Step-by-step explanation:
This is the sum of cubes. If you have choices you really should list them because often the way we write answers is not in agreement with what you are given.
Step One
Factor 64x^3 and 343 into prime factors.
64x^3: 4*4*4*x * x *x
343: 7 * 7 * 7
Step Two
Factor using the sum of cubes.
(4x + 7)([4x]^2 - 7*4x + 7^2)
(4x + 7)(16x^2 - 28x + 49)
60% are blue.
3/5 are blue.
2/5 are red.
There are 3 blue fish and 2 red fish.
