In order for the parallelogram to be a rhombus x=?

42

Step-by-step explanation:

Let's make an equation since all angles have to add up to 360

Equation: 360 = 2(3x-11)+2(x+23)

Step 1: Simplify both sides of the equation.

360=2(3x−11)+2(x+23)

360=(2)(3x)+(2)(−11)+(2)(x)+(2)(23)

360=6x+−22+2x+46

360=(6x+2x)+(−22+46)

360=8x+24

360=8x+24

Step 2: Flip the equation.

8x+24=360

Step 3: Subtract 24 from both sides.

8x+24−24=360−24

8x=336

Step 4: Divide both sides by 8.

Leaves us with x = 42

x = 17

Step-by-step explanation:

Step 1: We know in a rhombus the angles add up to 360

2(3x-11) + 2(x+23) = 360

Step 2: Solve the equation for 'x'

2(3x-11) + 2(x+23) = 360

6x - 11 +2x + 46 = 360

8x +35 = 360

8x = 360 - 35

8x = 325

x = 40.625

correct choice is b

step-by-step explanation:

when you calculate the average rate of change of a function, you are finding the slope of the secant line between the two points. for the function the average rate of change from point to point can be calculated as

to find the average rate of change from day 2 to day 10, note that at day 2, 8 houses were sold, so a(2,8) and at day 10, 2 houses were sold, so b(10,2). thus,
