4ry + 3rz + 8xy + 6xz
r(4y) + r(3z) + 2x(4y) + 2y(3z)
r(4y + 3z) + 2x(4y + 3z)
(r + 2x)(4y + 3z)

The answer is D.

In the rectangle below,

STALIN [3.7K]

Answer:

Step-by-step explanation:

In a rectangle, diagonals are equal and bisect each other

BE = AE

6x - 5 = 2x + 7

6x - 2x - 5 = 7

4x - 5 = 7

4x = 7 + 5

4x = 12

x = 12/4

x = 3

AE = 2x + 7

= 2*3 + 7

= 6 + 7

AE = 13

AC = 13 + 13

AC = 26

m∠EBC = 50

In rectangle, each angle is 90

m∠ABE + m∠EBC = 90

m∠ABE + 50 = 90

m∠ABE = 90 - 50

m∠ABE = 40

In rectangle, AB // DC and DB transversal

m∠ECD = m∠ABE { alternate interior angles}

m∠ECD = 40

Find the area or this triangle

Arlecino [84]

Answer:

Area of triangle = 15 square units

Step-by-step explanation:

We need to find area of the triangle, given the vertices:

A=(4,0)

B=(1,5)

C=(7,5)

The formula used is: $Area\:of\:triangle=\frac{1}{2}(x_1(y_2-y_3)+x_2(y_3-y_1)+x_3(y_1-y_2))$

We have: $x_1 =4, y_1 =0, x_2 =1, y_2=5, x_3=7 , y_3=5$

Putting values and finding area

$Area\:of\:triangle=\frac{1}{2}(x_1(y_2-y_3)+x_2(y_3-y_1)+x_3(y_1-y_2))\\Area\:of\:triangle=\frac{1}{2}(4(5-5)+1(5-0)+7(0-5))\\Area\:of\:triangle=\frac{1}{2}(4(0)+1(5)+7(-5))\\Area\:of\:triangle=\frac{1}{2}(0+5-35)\\Area\:of\:triangle=\frac{1}{2}(-30)\\Area\:of\:triangle=-15$
