Answer:

Option D.

Step-by-step explanation:

The given expression is (5r + 2)(3r minus 4)

Convert this expression into an algebraic expression.

(5r + 2)(3r - 4)

By distribution law,

= 5r(3r - 4) + 2(3r - 4)

= 15r² - 20r + 6r - 8

= 15r² - 14r - 8

Now convert the algebraic expression into the language form.

15r squared minus 14r minus 8

Therefore, option D is the answer.

Which of these statements are correct about a line segment with a length of 12 units in a coordinate plane? Select all that appl
Vitek1552 [10]

Correct statements are:

If it is reflected across the y-axis, its length still will be 12 units.

If it is rotated 270° about the origin, its length still will be 12 units.

If it is translated 15 units up, its length still will be 12 units.

<u>Step-by-step explanation:</u>

Whatever it may be rotation, reflection or translation, the size of the line will never change. So length of the line is same as 12 units in the image.

So the wrong statements are

If its reflected across y = -x then the length will no longer be 12 units.

If it is rotated 90° about the origin, then the length will no longer be 12 units.

If it is translated 18 units to the right,  then the length will no longer be 12 units.

(a) A square has all the 4 sides being equal while a rectangle has four sides, with the opposite sides being parallel and the same length.

(b) The diagonals bisect the angles , the diagonals are perpendicular bisectors of each other

(c) A square has two pairs of parallel sides, four right angles, and all four sides are equal while the angles of a parallelogram are not right angles

(d) a rhombus can be a rectangle (if the angles of the rhombus are all 90 degrees), and a rectangle can be a rhombus (if the sides of the rectangle are all equal length). Opposite sides are parallel.

(e) a rhombus has two opposite internal angles of equal measure, a square has four right angles with equal measure
