Answer:
-10
Step-by-step explanation:
So it skipped labeling a marker as a number between 10 and 2. The difference between 10 and 2 is 10-2=8.
Half of 8 is 4. So it is going down by 4 each time.
So start at the marker called 10.
The next marker would be 10-4=6.
The next labeled marked is 2 which would do get 2 from doing 6-4=2.
The next one below 2 would be 2-4=-2.
The next one below that one would be -2-4=-6.
The ? would be -6-4=-10.

Answer: a = 8; b = 15; c = 17
Step-by-step explanation:
c = b + 2 and c = 2a + 1
b = c − 2 and a =
c² = b² + a²
c = 1 or c = 17
If c = 1 then b = 1 - 2 = -1, that's not possible
So x = 17
b = 17 - 2 = 15
a =
Length sides of the triangle are 17 cm, 15 cm and 8 cm.
I saw some of this on a site but I want to make sure its correct so we're gonna apply the pythagorean theory and see if its correct.
This shows that this is correct.
Hope this helped! Again, some of this was from a site, not from me.
Answer:
x ≈ - 5.32, x ≈ 1.32
Step-by-step explanation:
Given
x² + 4x - 7 = 0 ( add 7 to both sides )
x² + 4x = 7
To complete the square
add ( half the coefficient of the x- term )² to both sides
x² + 2(2)x + 4 = 7 + 4
(x + 2)² = 11 ( take the square root of both sides )
x + 2 = ± ( subtract 2 from both sides )
x = - 2 ±
Thus
x = - 2 - ≈ - 5.32 ( to 2 dec. places )
x = - 2 + ≈ 1.32 ( to 2 dec. places )
