When it's in this form you simply see what two numbers add to the first and multiply to the second.

7+11= 18
7*11=77
both positive

A
(w+7)(w+11)

To find the factors, we must find all possible factors of c:

c = 77

Factors of 77: {1,7,11,77}

A set of factors must add up to b. Add these factors together:

b = 18
1 + 77 = 78
7 + 11 = 18

7 and 11 will be used in the factors.

The answer is A. (w + 7)(w + 11).

An electrician cuts a 136 foot long piece of cable. One piece is 16 feet less than 3 times the length of the other piece. Find t

Ugo [173]

Answer:

98 ft and 38 ft

Step-by-step explanation:

We know that the initial length of the piece is 136 feet

Then the piece is cut into two pieces.

Let's call x the length of the first piece of cable and call z the length of the second piece of cable.

So we know that

$x + z = 136$

and

$x = 3z-16$

Now we substitute the second equation in the first one and solve for the variable z

$3z-16 + z = 136$

$4z-16= 136$

$4z= 136+16$

$z= \frac{152}{4}$

$z=38\ ft$

Now we find the length x

$x + 38 = 136$

$x= 136-38$

$x= 98\ ft$

A bulletin board has a perimeter of 200 inches. Which equation expresses the area A(w) of the bulletin board as a function of it

o-na [289]

Answer: A(W) = 100W - $W^{2}$

Step-by-step explanation:

The formula for calculating the perimeter is given as :

P = 2 ( L + W )

the perimeter is given as 200 , that is

200 = 2 ( L + W )

Dividing through by 2 , we have

100 = L + W

Make L the subject of the formula ;

L = 100 - W

The formula for the area is given as Length x width , substituting the values , we have :

A = LW , since , L = 100 - W , we have

A = (100- W) (W)

A = 100W - $W^{2}$

Therefore :

A(W) = 100W - $W^{2}$
