If a rectangle's length is 7 more than 4 times the width and the perimeter is 54 what are the dimensions of the rectangle?

1 answer:

4 0

Let w = width of the rectangle
4w+7 = length of the rectangle 

perimeter = 2 lengths + 2 widths 

2w + 2(4w+7) = 54 
2w + 8w + 14 = 54 
10w = 40 
w = 4 
4w+7 = 23 

dimensions of rectangle: 
width = 4 
length = 23 hope this helps

Answer:

46th term of the sequence is 364

Step-by-step explanation:

first term = 4

common difference = 12 - 4 = 8

46th term = first term+(46 - 1)×common difference

so,

46th term = 4 + ( 45 ) × 8
46th term = 4 + 360
46th term = 364

Ksenya-84 [330]

Answer:

$26\sqrt{3}$

Step-by-step explanation:

We want to find $4\sqrt{3} +11\sqrt{12}$ . $11\sqrt{12}$ can be written as $11\sqrt{4*3}=11*\sqrt{4} *\sqrt{3}=11*2*\sqrt{3}=22\sqrt{3}$ , so we can now write our original equation as: $4\sqrt{3}+22\sqrt{3}$ .
