If x 1 and x 2 are the roots of quadratic polynomial of a x 2 + b x = c (i.e.the root of equation of a x 2 + b x + c = 0 ), then a x 2 + b x + c = a ( x − x 1 ) ( x − x 2 ) .This is the formula of factoring quadratic polynomial into factors
(Im sorry if this doesnt help)
30 = 2 x 3 x 5
54 =2 x 3x 3 x 3
GCF = 2 x 3=6
30 : 6 = 5; 54 : 6 = 9
30 + 54 = 6 x (5+8)
What is showing you need to divide then add and multiply
620÷55 =11.27
so, 55÷2 =27.05
620÷30=20
So the answer is
27 blue and 30 gray
Answer:
1. The first set of number is
1,2,3,4,5
Mean= 1+2+3+4+5/5
= 15/5
= 3
Median= 3
Mode= N/A
The next set of numbers is
2,3,4,5,6,6
Mean= 2+3+4+5+6+6/6
= 26/6
= 4.3
Median=4+5/2
= 9/2
= 4.5
Mode= 6
The next set of number is
6,7,5,4,5,6,2,5
Mean= 2+4+5+5+5+6+6+7/8
= 40/8
= 5
Median= 5+5/2
= 10/2
= 5
Mode= 5
Answer:
a. = 36km
b. Perimeter = 108km
c. Area = 486km^2
Step-by-step explanation:
Pythagoras theorem
a^2 + b^2 = c^2
27^2 + b^2 = 45^2
b^2 = 45^2 - 27^2
b^2 = 1296
b = 
b = 36km
Perimeter
a + b + c
27 + 36 + 45 = 108
Perimeter = 108km
Area = 
Area = 
Area = 
Area = 486km^2
