First you would want to find the length of one eraser and then multiply that by 2. To find the length of one you take the total length or all of them and divide it my the total number of them. 29 1/4 is 117/4.

(117/4) / 13 Dividing by something is the same as multiplying by the opposite.

117/4 × 1/13 = 117/52

Now you multiply by 2.

117/52 * 2/1 Cross simplify

117/26 * 1/1

117/26 inches or 4 1/2 inches.

Find the conjugate and product of<br><br>2-i5

WITCHER [35]

Answer: $2+i5,\ 29$

Step-by-step explanation:

Given

Complex number is $2-i5$

Its conjugate is obtained by changing the sign of the original number i.e. $2+i5$

The product of the two numbers is

$\Rightarrow (2-i5)(2+i5)=2^2-(5i)^2\quad \quad [(x+y)(x-y)=x^2-y^2]\\\\\Rightarrow (2-i5)(2+i5)=4-25i^2\\\\\Rightarrow (2-i5)(2+i5)=4+25=29$
