Length=2x
width=x
Perimeter of a rectangle=2(lenght)+2(width)

The first is to find out the measures of this rectangle, that is to say, you have to find the length and width of these rectangle.

We can suggest this equation:
24=2(2x)+2(x)
4x+2x=24
6x=24
x=24/6
x=4

2x=2(4)=8

The lenght will be 8 in, and the length will be 4 in.

The second; you have to calculate the area of this rectangle.
area of a rectangle= lenght x width

area=(8 in)(4 in)=32 in²

answer: the area of Marshall´s rectangular poster would be 32 in²

Look for a pattern and complete the conjecture.
denis-greek [22]

Answer:

390

Step-by-step explanation:

The formula of sum of arithmetic sequence is \frac{n}{2} (a+Tn)

The number of this series are 2, 4, 6, 8, 10, 12, .  .  .  .  , 60.

The first term ( a ) = 2

The 30th even number is 60

The Tn is the term of the sequence

So the equation is

30/2 x ( 2 + T_{30})

T_{30} = 60

30/2 x ( 2 + 60 )

30/2 x (62)

1860/2

In △ABC, m∠A=44°, m∠B=48°, and a=25. Find c to the nearest tenth.
Nookie1986 [14]

Answer:

=36.0

Step-by-step explanation:

We use the sine rule to find the missing sides as follows;

Lets find the missing angle C by using the summation of interior angles in a triangle.

C=180-(44+48)

=88°

Then,

a/Sin A=c/Sin C

25/Sin 44=c/Sin 88

c=(25 Sin 88)/Sin 44

c=35.97

The side c=36.0 to the nearest tenth.

A high school Philanthropy Club is collecting plastic waste which will be used to create benches for a local park. The volume of
Zolol [24]

Answer:

The expression 7x represents the height of the container.

Step-by-step explanation:

From the question:

We are being informed that; if the length of the container is half of a foot longer than its width.

Let the width be x;

Then the length of the container can now be ; x+1/2

We all known that the volume of a rectangular prism is : V= l×w×h

here;

l = length

w = width

h = height  

If we rewrite the given expression :

\mathbf{7x^3+3.5x^2};

Then we factor we make a similar coefficient  of  the above equation, the  remaining entities left in the parenthesis should be a linear term  with a leading coefficient of 1 to match the expression for the length of the container.

i.e

\mathbf{7x^3+3.5x^2}} \\ \\\mathbf{7x^2(x+1/2)}  \\ \\\mathbf{7*x*x*(x+1/2)}

Hence, if the length of the container is half a foot longer than its width, x, then the expression 7x represents the height of the container.
