The answer would be
X=-2y
Move all the terms that don't contain x to the right side and solve.
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.
The owners went to the trouble of drawing the sketch, because they needed it to make their plan. The least you could do is to let me see it.
Solution :- To find 4 x 754 using two different methods ,we have two methods
Method 1 :- 4 x 754
=4(700+50+4)
=4 x 700 + 4 x 50 +4 x 4 [By using distributive property]
= 2800 + 200 +16
= 3016 Ans
Method 2 :- 4 x 754
=4(750+4)
= 4( (5 x 150 )+4)
=4 x 5 x 150 + 4 x 4 [By using distributive property]
=(4 x 5) x 150 + 4 x 4 [associative property]
= 20 x 150+16
=3000+16
=3016 Ans
