Step-by-step explanation:

Find the Equation of a Line Given That You Know a Point on the Line And Its Slope. The equation of a line is typically written as y=mx+b where m is the slope and b is the y-intercept. If you a point that a line passes through, and its slope, this page will show you how to find the equation of the line.

Trapezia ABCD and PQRS are similar.<br> Find the area shaded in green.
avanturin [10]

The area shaded in green is 864 cm²

<h3>Similar figures</h3>

Similar figures, corresponding angles are congruent and the sides are ratio of each other. Therefore,

AB / PQ = CD / RS

30 / 10 = 24 / RS

30RS = 240

RS = 240 / 30

RS = 8 cm

let find the height of trapezium PQRS.

AB / PQ  = 36 / h

30 / 10 = 36 / h

30h = 360

h = 360 / 30

h = 12 cm

Therefore,

area of the green portion = area of ABCD - area of PQRS

<h3>Area of a trapezium</h3>
  • area = 1 / 2(a + b)h

Therefore,

area of ABCD = 1 / 2(24 + 30)36 =  1 / 2 (54)36 = 1944 / 2 = 972 cm²

area of PQRS = 1 / 2(10 + 8)12 = 1 / 2(18)12 = 216 / 2 = 108 cm²

Area of the green portion = 972 - 108 = 864 cm²

Simplify the expression (2 square root sign 27) - (3 square root sign 32)
monitta

Answer:

3\sqrt{3} - 4\sqrt{2}

Step-by-step explanation:

The expression (2 square root sign 27) - (3 square root sign 32) is 2\sqrt{27} - 3\sqrt{32}.

To simplify, simplify inside the radicals by removing perfect square factors.

\sqrt{27} =\sqrt{9*3} =3\sqrt{3}

\sqrt{32} =\sqrt{16*2} =4\sqrt{2}

The expression becomes 3\sqrt{3} - 4\sqrt{2}.

This cannot be simplified anymore because whats under the radical is not the same.

Why do you sometimes have only one multiplication sentence for an array
taurus [48]

Arrays are useful models for multiplication which can be used in a variety of ways, ranging from highly structured lessons to games and open investigations. An array is formed by arranging a set of objects into rows and columns. Each column must contain the same number of objects as the other columns, and each row must have the same number as the other rows.


The following array, consisting of four columns and three rows, could be used to represent the number sentence 3 x 4 = 12.
