Answer:
5
Step-by-step explanation:
→ Let x = √20 + √20 .....
x
→ Square both sides
x² = 20 + √20 +√20 + √20
→ Replace √20 +√20 + √20 with x
x² = 20 + x
→ Move everything to the left hand side
x² - 20 - x = 0
→ Factorise
( x + 4 ) ( x - 5 )
→ Solve
x = -4 , 5
→ Discard negative result
x = 5
Answer:
C
Step-by-step explanation:
The x- intercept is where the line crosses the x- axis. At this point on the x- axis the y- coordinate is zero.
To find the x- intercept let y = 0 in the equation and solve for x, that is
5x - 2 = 0 ( add 2 to both sides )
5x = 2 ( divide both sides by 5 )
x =
← x- intercept
coordinates of x- intercept are (
, 0 ) → C
