Answer:
how is this meant to be a complete question? :D
43 as you substitute 6 in place of x, and then get 36+6+1=43
Extranious solution is mostly when you take the square root of negative number
what you want to do is math stuff
translate
remember that
so
7.
add 2 to both sides
square both sides
cube root both sides
x+1=9
minus 1
x=8
8.
square both sides
using math
0=x²-5x-6
x=6 or -1
if we do x=-1, we get
√4=-2, which is kind of true, but we normally find the principal root (posiitive0
-1 is extraious
x=6
9.
add √(x-1) to both sides then square both sides
minus (x+5) from both sides
square both sides
using math
x=-1 or 15
if we had x=-1, we would be having √(-1-1) which is sqrt of negative which is not allowed
x=15

Answer:</h2><h2>
The height of the triangle = 4cm</h2>
Step-by-step explanation:
Given, area of the triangle = 10
Let the height of the triangle be h cm
Given, the base b is 3 cm less than twice its height.
b = 2h - 3 ... (1)
By formula, area of the triangle = bh .. (2)
substitute (1)in (2), we get
Area = (2h-3) h
10 = (2h-3) h
20 =
- 20 = 0
solving the equation, we get x = 4, -2.5
The height of the triangle = 4cm
Answer: "It is IMPOSSIBLE to determine the relationship."
_________________________________________________________
Because number "a" could be "30" ; and number "b" could be: "6 trillion"; for example. Or, number "a" could be "6 trillion" and number "b" could be "30".
OR; "a" could equal "b" ; for example.
