Answer:
(i) The factors of the given polynomial is (x – 22) and (x + 10)
(ii) If she purchase 5kg papaya then she pays 110
Step-by-step explanation:
<h3><u>Given</u>;</h3>
- p(x) = x² – 12x – 220 per kg
<h3><u>To Find</u>;</h3>
- The factors of the given polynomial
- if she purchase 5kg papaya, what money she have to pay?
<h3>(i)</h3>
Now,
x² – 12x – 220 = 0
Splitting the middle term
x² – 22x + 10x – 220 = 0
x(x – 22) + 10(x – 22) = 0
(x – 22) + (x + 10) = 0
x – 22 = 0 or x + 10= 0
x = 22 or x = -10
Here, (-10) is the negative value hence it is not possible
So, The value of x is 22
The factors of the given polynomial is (x – 22) and (x + 10)
<h3>(ii)</h3>
if she purchase 5kg papaya then,
we know the price of 1 kg papaya i.e., 22 per kg
So,
5 × 22 = 110
Thus, if she purchase 5kg papaya then she pays 110

Answer:
x= 4
JN=6.5
Step-by-step explanation:
1) JK=LM
13= 3x+1
12=3x (Subtract 1 from both sides)
4=x (Divide 3 from both sides)
2) JN is half of KJ
JN= 13/2
JN=6.5
Answer:
C. 2(2x + 3)(2x - 3)
Step-by-step explanation:
3 1/8
First you take the all the dogs that gained 3/4 (which is 4)
Then you multiply it by 4
3/4x4=3
Then you add the dogs that gained 1/8 of a pound
3+1/8=3 1/8
Answer:
We get 
Step-by-step explanation:
We are given:
We need to find (f-g)(x) (assuming there is x in the bracket, i.e. (f - g) () should be (f-g)(x))
We would simply subtract f(x) and g(x)
So, We get
