Answer:
100
Step-by-step explanation:
7 - (-93) = 100
-93 - (-193) = 100
-193 - (-293) = 100
As we can see, we get 100 for subtracting them all.
Best of Luck!
Answer:
The answer is 290°
Step-by-step explanation:
Work in rates per hour. These rates can then be added to form an equation
1/13 + 1/10 = 1/x where x is the time for both working together
multiply thru by 130x:-
10 x+ 13 x = 130
x = 130/23 = 5.65 hours or about 6 hours 39 minutes
38,428 - 21,728= $16,700 left over
Answer:
-4
Step-by-step explanation:
Ok first we can factor out 3x and get
![f(x)=3(x^3+4x^2+x+6)](https://tex.z-dn.net/?f=f%28x%29%3D3%28x%5E3%2B4x%5E2%2Bx%2B6%29)
then factor it
![f(x)=3(x^2(x-1)+5x(x-1)+6(x-1))\\f(x) = 3(x-1)(x^2+5x+6)\\f(x) = 3(x-1)(x+3)(x+2)\\x = 1, -3, -2](https://tex.z-dn.net/?f=f%28x%29%3D3%28x%5E2%28x-1%29%2B5x%28x-1%29%2B6%28x-1%29%29%5C%5Cf%28x%29%20%3D%203%28x-1%29%28x%5E2%2B5x%2B6%29%5C%5Cf%28x%29%20%3D%203%28x-1%29%28x%2B3%29%28x%2B2%29%5C%5Cx%20%3D%201%2C%20-3%2C%20-2)
add em together, we get -4
