The perimeter of a rectangle is 48 in. If the length is twice the width, what is the length of the rectangle?

Answers

Answer 1

Answer: Step one: We need to find the formula for perimeter. And we can't just say "count all the sides". How can we express it? It's length + length + width + width, right? Let's size that down a little bit. 2*length 2*width. We'll use w to express "width" and 2w to express "length".
2(w)+2(2w)=48.
6w=48.
w=8.
Since length is twice the width, 8*2 is 16. Length=16.

You can check it by substituting the different values for length and width into the equation 2w+2l=perimeter.
2(8)+2(16)=48. Is this true? Yep! So you know you're right.

Answers

Answer:

The area of the brick border is $(24x+144)\ ft^(2)$

Step-by-step explanation:

we know that

The area of the brick border is equal to

$A=(x+12)(x+12)-(x)(x)\n \nA=(x+12)^(2) -x^(2)\n \nA=x^(2)+24x+144-x^(2)\n \nA=(24x+144)\ ft^(2)$

Create a table of values for the given function.Function: f(x)=−4x+3

x
y
−2
−1
0
1
2

Answers

To create a table of values for the given function f(x) = -4x + 3, we need to substitute the given values of x into the function and calculate the corresponding y values.

Here's the table:

x y

-2 11

-1 7

0 3

1 -1

2 -5

To find the corresponding y values, we plug each x value into the function:

f(-2) = -4(-2) + 3 = 11

f(-1) = -4(-1) + 3 = 7

f(0) = -4(0) + 3 = 3

f(1) = -4(1) + 3 = -1

f(2) = -4(2) + 3 = -5

So, the table of values for the function f(x) = -4x + 3 is as follows:

x y

-2 11

-1 7

0 3

1 -1

2 -5

Answer:

Step-by-step explanation:

To find the 4th term, you simply put 4 in for n because n denotes which term:

$-7+6(n-1)=-7+6(4-1)=-7+6*3=-7+18=11$

The answer is thus 11.
