\\ \sf\longmapsto 1-(2x+4)=-4x+5

\\ \sf\longmapsto 1-2x-4=-4x+5

\\ \sf\longmapsto -2x-3=-4x+5

\\ \sf\longmapsto -2x+4x=5+3

\\ \sf\longmapsto 2x=8

\\ \sf\longmapsto x=\dfrac{8}{2}

\\ \sf\longmapsto x=4

Answer:

x = 4

Explanation:

3x - 4y = 36

5x + 2y = 8 ( multiply all by two )

3x - 4y = 36

10x + 4y = 16

13x = 52

Divide by 13

x = 4 hope this helps

I need major help pls help

Answer:

No, since 832 ≠ 900, using Pythagorean theorem, the width should be 18 in

Step-by-step explanation:

It is better to type the question in the 'Question' than the fact that you need help so that we can start seeing the problem immediately.

A rectangle has 4 right angles so if l = 24 and w = 16 then you can use the pythagorean theorem to see if this is possible since

24^2 + 16^2 = 30^2 since the diagonal is the hypotenuse of the triangles formed by the diagonal in the rectangle.  

576 + 256 ≠ 900, since the left side is 832 and the right side is 900

It would be more correct if the width is 18 since 576 + 18^2 = 900
