Solve the equation for x. the square root of the quantity x plus 4 end quantity minus 7 equals 1 x = 4 x = 12 x = 60 x = 68

x = 60

Step-by-step explanation:

Given

- 7 = 1 ( add 7 to both sides )

= 8 ( square both sides )

( )² = 8² , that is

x + 4 = 64 ( subtract 4 from both sides )

x = 60

an altitude of 15,000 feet

step-by-step explanation:

false

step-by-step explanation:

the reason i say this is because for a certain length of sides you can pick any two and the length is wither equal or greater than the third side and in this case it's not.

3 + 5 = 8

8 is smaller than 9 which is the third side.

hope this : )
