Answer:
Step-by-step explanation:
a) perimeter = 8x + 3 + 5 + 7x + 4
b) perimeter = 15x + 12
x = -16 or x = 5
Solution:
Given polynomial:
To find the roots of the polynomial.
Split the middle term 11x.
11x = 16x - 5x
Take the x common in first 2 terms an -5 common in next 2 terms.
Take (x + 16) common in both terms.
x + 16 = 0 or x - 5 = 0
x = -16 or x = 5
Hence x = -16 or x = 5.
Answer:45
Step-by-step explanation:
Let the unit place be ‘x'
Tenth place be y
The number is 10y+x
x+y = 9 (according to the condition) (1)
Digits are interchanged Unit place' y ‘& tenth place ‘ x'
New no is 10x +y
This is 9 more than the original number
10x+ y = 10y+x +9
10x-x+y-10y = 9
9x-9y= 9
x-y = 1 (dividing by 9) (2)
Adding the two equations
2x = 10
x= 5
Substituting the value of x in first equation
y = 4
The number is 45, the original number is 54 this is 9 more of the new number.
