Answer:
3:2
Step-by-step explanation:
Answer:
m<9=130 it also equal to 180 so 130-180 makes m<4= 50
Answer:Jason is 5 years old.
John is 4 years old.
Jackson is 12 years old.
Step-by-step explanation:
Let x represent the age of Jason.
Let y represent the age of John.
Let z represent the age of Jackson.
The ages of three siblings Jason John and Jackson totals 21 years. It means that
x + y + z = 21 - - - - - - - - - - -1
Jason is one year older than John. It means that
x = y + 1
Jackson is three times as old as John. It means that
z = 3y
Substituting x = y + 1 and z = 3y into equation 1, it becomes
y + 1 + y + 3y = 21
5y = 21 - 1 = 20
y = 20/5 = 4
x = y + 1 = 4 + 1
x = 5
z = 3y = 3 × 4
z = 12
Solution:
The Quadratic polynomial in variable x is :
→ 6 x² + x -7
Breaking the middle term i.e term containing variable x
= 6 x² + 7 x - 6 x -7
= x ( 6 x +7) - 1 (6 x +7)
= (6 x + 7)(x-1)→→→Factor of 6 x² + x -7
