Answer:

2(2 + 3x).

Step-by-step explanation:

The greatest common factor of 4 and 6x is 2, so we divide by 2 to get the factors:

4 / 2 = 2 and 6x / 2 = 3x so:

4 + 6x

= 2(2 + 3x).

ziro4ka [17]

Answer: ANOVA

Step-by-step explanation:

A rectangle has coordinates A(-4?4), B(0,0), C(6,8), and D(2,11) what is the area of the rectangle
Pani-rosa [81]

Answer:

The area of the rectangle is 56

Step-by-step explanation:

Thank you for this question.

find the distance between AB and BC

the formula for that is \sqrt{(x2-x1)^2+(y2-y1)^2}

lets do this first

AB=\sqrt{((0--4)^2+(0-4)^2)} \\AB=\sqrt{4^2+(-4)^2} \\AB=\sqrt{16+16} \\AB=\sqrt{32} \\AB=5.6\\\\BC=\sqrt{(0-6)^2+(0.8)^2}\\BC=\sqrt{(-6)^2+(-8)^2}\\BC=\sqrt{36+64}\\BC=\sqrt{100}\\BC=10

Now multiply the lengths of AB and BC

10*5.6=56

The area of the rectangle is 56

Hope this helps :)
