Answer:

x = 4

Step-by-step explanation:

A trapezium is a quadrilateral (has four sides and four angles) with one pair of parallel sides. A trapezium is said to be isosceles if the bases are parallel, the two other sides known as the legs are equal and diagonals of the trapezium are equal to each other.

In trapezoid ABCD, BC and AD are the diagonals.

Hence BC = AD (property of isosceles trapezoid)

9x + 1 = 12x - 11

Simplifying:

12x - 9x = 1 + 11

3x = 12

Dividing both sides by 2:

x = 4

Answer:

slope (m) = -\frac{3}{2}

Step-by-step explanation:

We can find the slope (m) by using coordinate pairs of any 2 points located along the slope of the line that we have on the graph.

This, let's use the coordinate pairs at:

x = -4, y = 2 (-4, 2) => (x2, y2)

x = 0, y = -4 (0, -4) => (x1, y1)

slope (m) = \frac{y2 - y1}{x2 - x1}

slope (m) = \frac{2 -(-4)}{-4 - 0}

slope (m) = \frac{2 + 4}{-4 - 0}

slope (m) = \frac{6}{-4}

slope (m) = \frac{3}{-2}

slope (m) = -\frac{3}{2}

3(x + 1) - 2x = -6 what is X i need halp
Mashutka [201]

Answer:x=−9

Step-by-step explanation:

Apply the distributive property.

3 x + 3 ⋅ 1 − 2 x = − 6

Multiply  3  by  1

.

3 x + 3 − 2 x = − 6

Subtract 2x from 3x.

x + 3 = − 6

Move all terms not containing  x  to the right side of the equation.

Subtract 3 from both sides of the equation.

x = − 6 − 3

Subtract 3 from − 6 .

x = − 9

What is the area of this figure? Enter your answer as a decimal in the box. cm² A parallelogram with a length of 11 cm. A triang
Art [367]
Given:
Parallelogram length = 11 cm
triangle atop the parallelogram : short leg = 7 cm
Right triangle inside the parallelogram : long leg = 9cm

Area of parallelogram = base * height
A = 11cm * 9cm
A = 99 cm²

Area of a triangle atop the parallelogram:
A = ab/2
A = (11cm * 7cm)/2
A = 77 cm² / 2
A = 38.5 cm²

Total area of the figure
99 cm² + 38.5 cm² = 137.5 cm²
