34.9 because its 90 angle so you subtract the 55.1
If you mean (3n-2m)^2 then the answer is
9n^2-12mn+4m^2
So B
Answer:
n = 9
Step-by-step explanation:
3(n+7)=48
distribute
3n +21 = 48
subtract 21 from each side
3n = 48-21
3n = 27
divide by 3
3n/3 = 27/3
n = 9
Answer:
2.4x-4.4
Step-by-step explanation:
0.3(4x-8)-0.5(-2.4x+4)
1.2x-2.4+1.2x-2
2.4x-4.4
Answer:
88 in²
Step-by-step explanation:
The shape of a pizza = Circular
Area of a circle = πr²
For Martin
Martin ordered a pizza with a 12-inch diameter.
Radius = Diameter/2 = 12 inch/2 = 6 inch
Area of Martin's pizza = π × 6²
= 113.09733553 in²
≈ 113.1 in²
For Ricky
Ricky ordered a pizza with a 16-inch diameter.
Radius = Diameter/2 = 16 inch/2 = 8 inch
Area of Martin's pizza = π × 8²
= 201.06192983in²
= 201.1in²
The approximate difference in area of the two pizzas in square inches is calculated as:
201.1 in² - 113.1 in²
= 88 in²
