Let w = width of the rectangle
<span>4w+7 = length of the rectangle </span>
<span>perimeter = 2 lengths + 2 widths </span>
<span>2w + 2(4w+7) = 54 </span>
<span>2w + 8w + 14 = 54 </span>
<span>10w = 40 </span>
<span>w = 4 </span>
<span>4w+7 = 23 </span>
<span>dimensions of rectangle: </span>
<span>width = 4 </span>
<span>length = 23 hope this helps</span>
Answer:
I. D: 
ii. R: 
iii. Y-int: 
Step-by-step explanation:
i) The given absolute value function is

The domain is all values of x that will make the function defined.
The absolute value function is defined for all real numbers.
The domain is all real numbers.
ii) The range is the values of y for which x is defined.
The given absolute value function is

This function has the vertex at
and it is reflected in the x-axis therefore the vertex is the maximum point on the graph.
The y-value of the vertex is the maximum value on the graph.
Hence the range is 
iii) To find the y-intercept, we put x=0, into the function to get;




The y-intercept is
or (0,-6)

Find the rate:
51 ÷ 3 = £17
1 kg of beef = £17
2 kg of beef = £17 × 2 = £34
2 kg beef = £34
i think the answer is 42 but i don’t know how to get in into its smallest form but i hope this helps
