For the first one yes because you add essentially 1, but three times so you have 3x's whish is 3x. for problem two you get 8xy because of the common base number. number two is no. for number three. no,because you distribute the negative which woukd make negative x minus 8. number problem 4 yes because distrubute the 4 to the x and 5
x=25
Step-by-step explanation:
2000=400√x
Step 1: Flip the equation.
400√x=2000
Step 2: Divide both sides by 400.
400√x/400=2000/400
√x=5
Step 3: Solve Square Root.
√x=5
x=52(Square both sides)
x=25

Answer:
8.16 Kg
Step-by-step explanation:
average is calculated as
average = 
here average = 0.17 and count = 48 , then
