Answer:
−10x+3
Step-by-step explanation:
Answer:
x^2 - 10x + 21
Step-by-step explanation:
Sum of zeros
= 7 + 3
= 10
Product of zeros
= 7 x 3
= 21
x^2 - ( sum of zeros )x + product of zeros
= x^2 - 10x + 21
The Quadratic polynomial is x^2 - 10x + 21.
a) 2/7
There are a total of 14 pairs of socks (4+2+8) so 14 is your denominator.
Then you take however many red socks there are and that is your numerator (4).
Then you simplify. 4/14 ; 2/7
b) 1/4
There are a total of 40 headbands (10+6+24) so 40 is your denominator.
Then you take however many red headbands there are and that is your numerator (10).
Then you simplify, 10/40 ; 2/8 ; 1/4
c) 15/28
You then add 2/7 and 1/4.
Answer:
41
Step-by-step explanation:
Yes, it is easy.
Square root of (40*40+9*9) = 41
