Solution:

The Quadratic polynomial in variable x is :

→ 6 x² + x -7

Breaking the middle term i.e term containing  variable x

= 6 x² + 7 x - 6 x -7

= x ( 6 x +7) - 1 (6 x +7)

= (6 x + 7)(x-1)→→→Factor of 6 x² + x -7

gulaghasi [49]

The length of the shorter wire that the electrician cuts so that the difference between those two is of 5 m is 22.5.

Given to us

An electrician needs to cut a 49 m piece of wire into two pieces so that one piece is 5 m longer than the other piece.

<h3>What are the two equal parts of the wire?</h3>

We know that the length of the wire is 49 m, therefore, to cut the wire in two equal parts divide the total length of the wire by two,

\dfrac{49}{2} = 24.5

Thus, the length of each side will be 24.5.

<h3>What is the length of the shorter piece of wire?</h3>

Since we need to cut the wire such that one side of the wire is 5 less than the other, we already know the length of the equal sides deduct (5/2) from both sides to create a difference between the length of the wire.

Length of the shorter wire = 24.5 -2.5 = 22.5

Length of the longer wire = 22.5 + 5 = 27.5

Hence, the length of the shorter wire that the electrician cuts so that the difference between those two is of 5 m is 22.5.

f(x)=8(x−3)+13

f(5)= 8(5-3)+13

f(5) = 8(2) +13

f(5) = 16 +13

f(5)= 29

Hope this helps!
