Sqrt(5u + 2) = sqrt(3u + 14)
Square both sides to clear the square root.
5u + 2 = 3u + 14
subtract 3u from both siides
2u + 2 = 14
subtract 2 from both sides
2u = 12
divide both sides by 2
u = 6
When you square a square root you MUST check the solution.
sqrt(5*6 + 2) = sqrt(3*6 + 14)
sqrt(32) = sqrt(32)
Answer:
27
Step-by-step explanation:
1^3 = 1
2^3 = 8
3^3 = 27
4^3 = 64
5^3 = 125
The missing number is 27.
B. is the answer if you look closely
Answer:
The equation has one solution.
Step-by-step explanation:
6x + 35 = -6x - 35
subtract 6x from both sides of the equation
35 = -35 - 12x
add 35 to both sides of the equation
70 = -12x
divide -12x on both sides of the equation
x = 5.833333333
