To find the sum of all the odd integers from to 49 inclurive

2401 is the sum of first 49 odd numbers.

Step-by-step explanation:

Address the formula, input parameters & values.

Input parameters & values:

The number series 1, 3, 5, 7, 9, . . . . , 97.

The first term a = 1

The common difference d = 2

Total number of terms n = 49

apply the input parameter values in the AP formula

Sum = n/2 x (a + Tn)

= 49/2 x (1 + 97)

= (49 x 98)/ 2

= 4802/2

1 + 3 + 5 + 7 + 9 + . . . . + 97 = 2401

Therefore, 2401 is the sum of first 49 odd numbers.

1. a^4+8a^3+24a^2+32a+16

2.y^8+8y^7+28y^6+56y^5+70y^4+56y^3+28y^2+8y+1

3.x^6-3x^4y^2+3x^2y^4-y^6

perimeter = 10 +  √10  units

explanation:

first, we will need to get the length of each line using the distance formula which is as follows:

distance = 

1- length of ab:

ab =   = 5 units

2- length of ac

length of ac is the same as ab = 5 units

3- length of bc:

bc =   =  √10  units

now, we can get the perimeter by adding the side lengths as follows:

perimeter = 5 + 5 +  √10

perimeter = 10 +  √10  units

hope this : )
