Answer:
Hope it works for u
Step-by-step explanation:
As we have given two shapes bathroom
square and rectangle
Parameter of square= sum of all the sides ( : In square all sides are equal
Parameter of square= 4*L = 4*(x+3) (:L=x+3
similarly,
In rectangle opposites sides are equal hence
Perimeter of rectangle= 2*length+2*width ( : length=x+4,width can't be seen clearly so I assume and take it width=x+1 hope this is equal to the width of ur question otherwise do the calculation by ur self).
Perimeter of rectangle= 2*(x+4)+2(x+1)
so now we have to find the value of "x" for which both perimeter are equal, so
perimeter of square= perimeter of rectangle
4*(x+3)=2*(x+4)+2(x+1) we can also write as
<h2>
2(x+3)+2(x+3)=2(x+4)+2(x+1)</h2><h3>
This is the linear equation required</h3><h3>
now to find value of "x"</h3><h3>
simplify both sides, we get</h3><h3>
4x+12=4x+10</h3><h2>
0≠2 so that not true and also there is no value of "x"</h2>
for which both parameters become equal
<h2>
so from my side "b" option is correct</h2>
Please brain-list it if u find it help-full it requires effort!

Hello!
I was going to try to use the slope formula, and solve for the y-intercept, but the given graph is hard to distinguish accurate ordered pairs. So, we will find the equation with the graph instead.
Looking at the graph, we can see that the y-intercept is negative. Also, we can also determine that each square represents one unit. So, the y-intercept has to be -3/2 or -1.5. That removes the choices A and C because the y-intercept is in between the values of -1 and -2.
Secondly, the graph has a positive slope. Why? When the x-values increase, the y-values increase. Also, when the x-values decrease, the y-values also decrease. This tells us that the graph has a positive slope (this doesn't remove any choices, but it helps to distinguish which graph has a positive or negative slope).
Finally, we know that if the slope is greater than one, then it is steeper (m > 1). But, if it's less than one, then it becomes less steep (0 < m < 1). Looking at the graph, the graph looks relatively steep (graphing the equations y = 5/7 x - 3/2 and y = 7/5x - 3/2 can help you see the differences between them).
Therefore, the equation of the line given by the graph is choice D, y = 7/5 x − 3/2.
Answer:
Step-by-step explanation:
2 l + 2w = 34 ⇔ l + w = 17 ⇒ l = 17 - w ..... <em>(1)</em>
l w = 66 ..... <em>(2)</em>
<em>(1)</em> ----> <em>(2)</em>
(17 - w) w = 66
w² - 17w + 66 = 0 ⇔ (w - 6)(w - 11) = 0
w = 6 cm
l = 11 cm
