Answer:
100.48 feet
Step-by-step explanation:
The circumfrence of a circle is represented in the equation C=2\pi r^{2} 
So we input the values into the equation C=2(3.14)(4)^2 which when entered into a calculator gives you 100.48feet
 
        
             
        
        
        
3x+7y=-6 -7x+3y=26 -4x+4y=-32 +4x on both sides and you end up with 4y=-32+4x now divide both sides by 4 and you get y=-8+x then to incorporate that in one of the problems 3x+7(-8+x)=-6 do the distributive property with the 7 into the () and you get 3x-56+7x=-6 now add all common variables and get 10x-56=-6 now add 56 to both sides and you get 10x=50 now divide by 10 on both side and you get x=5 now for getting y to equal a number instead of an equation 3(5)+7y=-6 15+7y=-6 subtract 15 on both sides to get 7y=-21 not divide by 7 on both sides to get y=-3 your answers are y=-3 and x=5
        
             
        
        
        
36x34= 1224cm²
(36-4)x(34-4)= 32x30= 960cm² 
Area of frame= 1224 
Area of picture inside frame= 960
So border = 1224-960= 264
ANSWER = 264cm²
        
             
        
        
        
Answer:
OD.(x-3)(x-2)
Step-by-step explanation:
we need two numbers (negative ir positive) that multiply to get 6 abd add to get -5.
 so its OD 
as -3×-2=6
and -3+-2=-5
 
        
             
        
        
        
Answer:
64
Step-by-step explanation:
Perfect squares are integers multiplied by themselves. 
- 2 times 2  = 4
- 3 times 3  = 9
- 4 times 4  = 15
The closest perfect squares to 54 are 49 (7^2) and 64 (8^2). 
49 is less than 54, so that's ruled out. 
Therefore, the closest perfect square to 54 that is greater than it is 64.
