Question

874*6+874*3+874
Simplify it by using distributive property​

Answer 1

Answer:

A standard unit of measurement is a quantifiable language that helps everyone understand the association of the object with the measurement. Although measurement is an important part of everyday life, kids don't automatically understand the different ways to measure things.

Step-by-step explanation:

Given

a

2

=13 and a

5

=25

We know that

a

n

=a+(n−1)d

∴a

2

=a+(2−1)d

⇒13=a+(2−1)d

⇒a+d=13 ...(i)

and a

5

=a+(5−1)d

⇒25=a+4d

⇒a+4d=25 ...(ii)

Now, subtracting (i) from (ii), we get

3d=12

⇒d=4

Now a+d=13 [from (i)]

⇒a=9

Hence, a

7

=a+6d=9+6(4)

⇒a

7

=33
