Answer:

x= -1/2 = -0.500

x=4

Step-by-step explanation:

2x^2-7x-4=0

2x^2-8x+1x-4=0

2x(x-4)+1(x-4)=0

(2x+1)(x-4)=0

2x+1=0...2x= -1.. x= -1/2         x-4=0 .. x=4

checking the solution

2(-1/2)^2-7(-1/2)=4.....  4=4

2(4)^2-7(4)=4....... 4=4

A square and a rectangle have the same perimeter is the length of the side of the square is 4X minusone the score of the rectang
Assoli18 [71]

Square Perimeter = 4(4x-1)

Rectangle Perimeter = 2(2x+1) + 2(x+2)

Square Perimeter = Rectangle Perimeter

4(4x-1) = 2(2x+1) + 2(x+2)

16x - 4 = 4x + 2 + 2x + 4

16x - 4 = 6x + 6

-6x +4 -6x +4

10x = 10

x = 1
