5) -7 (-15w + 21) + 3(18 - 27w)
Step 2: 105w - 81w - 147 + 54
6)
step 3: 24w - 93
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!
