In rectangle, the diagonal bisects each other,

BE=ED

$2x + 4 = 7x - 1 \\ or \: 2x - 7x = - 1 - 4 \\ or \: - 5x = - 5 \\ or \: x = \frac{ - 5}{ - 5} \\ x = 1$

Hope this helps..

Good luck on your assignment..

Need help rn 30 points

Ilia_Sergeevich [38]

Answer: X = ( $-\frac{5}{4}\\$ , 6)

Step-by-step explanation:

x(4x - 19) = 30

4x^2 - 19x = 30

4x^2 - 19x - 30 = 0

ax^2 + bx + c = 0

$X{1}=$ $\frac{-b+\sqrt{b^{2} -4ac}}{2a}\\$ = $\frac{19+\sqrt{(-19)^{2} -4(4)(-30)}}{2(4)}\\$ = 6

$X{2}=$ $\frac{-b-\sqrt{b^{2} -4ac}}{2a}\\$ = $\frac{19-\sqrt{(-19)^{2} -4(4)(-30)}}{2(4)}\\$ = $-\frac{5}{4}$ = -1.25

X = ( $-\frac{5}{4}\\$ , 6)
