Answer:
the answer is 1 1/3
Step-by-step explanation:
PQ is the same length as QR
therefore you would set the equations equal to each other
10x+10= 7x+14
-7x -7x
3x+10=14
-10 -10
3x= 4
/3 /3
x=1 1/3
Answer: e) 6
Step-by-step explanation:
Let x be mother + children = 18
Father's age = 38
Average age of the family = 14
38 + 18x /( x + 1 )= 14
Opening the bracket
38 + 18x = 14x + 14
Collecting like terms
24 = 4x
x = 6
no of children in the family is 6.
Answer:
Step-by-step explanation:
roots are (2+3i) and (2-3i)
reqd. eq. is (x-2-3i)(x-2+3i)=0
or (x-2)²-(3i)²=0
or x²-4x+9-9i²=0
or x²-4x+9+9=0
or x²-4x+18=0
