A rectangular fence has a perimeter of 184 feet. The length is four feet less than three times the width. Find the length and th

morpeh [17]

Answer:

lenth = 68 [ft]; width=24 [ft].

Step-by-step explanation:

1) if the length is 'l' and the width - 'w', then it is possible

2) to write the condition 'The length is four feet less than three times the width' as 3w-4=l;

3) to write the given perimeter as 2(w+l)=184.

4) then it is possible to make up the system:

$\left \{ {{2(w+l)=184} \atop {3w-4=l}} \right. \ = > \ \left \{ {{w+l=92} \atop {3w-l=4}} \right. \ = > \ \left \{ {{w=24} \atop {l=68}} \right.$

What is the value of n such that the expression x² + 11x + n is a perfect square trinomial? a. 11. b. 25. c. 30. d.25. e.36

lapo4ka [179]

Answer:

The value of n is 30.25.

Step-by-step explanation:

The given expression is

$x^2+11x+n$ ....(1)

The perfect square trinomial are defined as

$(x+y)^2=x^2+2xy+y^2$ .....(2)

On comparing (1) and (2), we get

$2y=11$

$y=\frac{11}{2}$

The given expression is perfect square trinomial if

$n=y^2$

$n=(\frac{11}{2})^2$

$n=\frac{121}{4}$

$n=30.25$

Therefore the value of n is 30.25.

-(y-7)=14 solve the following equation

enyata [817]

First, distribute the negative sign and get -y + 7 = 14

then subtract 7 from both sides and get -y = 7

Divide both sides by -1 and get y = -7

Hope this helps :)
