Answer:

Option D. 3

Step-by-step explanation:

For all the given options, let's substitute these values and check what length do they give for 5x+3.

A) -0.2:

5x+3 = 5 (-0.2) + 3 = 2

B) 0:

5x+3 = 5 (0) + 3 = 3

C) 1:

5x+3 = 5 (1) + 3 = 8

D) 3:

5x+3 = 5(3) + 3 = 18

So in my opinion, the option D. 3 cannot be possible value for x. The reason being that 3 gives us a length of 18 which is already shown in the diagram as the longest length.

While 5x+3 looks way smaller than the one shown by 18.

-0.2 is not a possible value of x because lengths cannot be negative.

If AB = x+ 4, BC = 2x -10 and AC

lawyer [7]

Answer:

Step-by-step explanation:

By the diagram, you can see the sum of segment AB and segment BC is segment AC. Adding the given expressions for AB and B is $3x-6$ . Simplifying the equation $3x-6=2x+1$ , gives $x=7$ . Substituting $x=7$ in the equation for segment AC gives 15.

Use the properties of quadrilaterals to complete the statements. A has exactly one pair of parallel sides. A must have two pairs

vesna_86 [32]

Answer:

1. Trapezoid

2. Kite

3. Square, Rhombus

Step-by-step explanation:

Given - Use the properties of quadrilaterals to complete the statements.

To find - A ..... has exactly one pair of parallel sides.

A ....... must have two pairs of adjacent sides congruent.

A ........ must have all congruent sides.

Proof -

A Trapezoid has exactly one pair of parallel sides.

A Kite must have two pairs of adjacent sides congruent.

A Square, Rhombus must have all congruent sides.

Reason -

A trapezoid is a quadrilateral with exactly one pair of parallel sides.

A kite is a quadrilateral with exactly two pairs of adjacent congruent sides.

A rhombus is a parallelogram with four congruent sides.

A square can be defined as a rhombus which is also a rectangle . In other words, a square is a parallelogram with four congruent sides and four right angles.

Answers in Explanation

Step-by-step explanation:

First Question:

$\sqrt{100}$ + [18 ÷ 3 x 4 - 15] - (60 - 7^2 - 1)

$\sqrt{100}$ + [24 - 15] - (60 - 49 - 1)

$\sqrt{100}$ + 9 - 10

10 + 9 - 10

Answer = 9

Second Question:

5x + 2x = 7x

5x^2 + 3x^2 = 8x^2

2x + 3x - x = 4x

2x + 3y + x + y = 3x + 4y

9x - 6x = 3x

-7y + 3x + 4x + 3y = 7x - 4y

-7x^2 + 2x^2 + 9x^2 = 8x^2

(3x^2 + 5x + 4) - (-1 + x^2) = 2x^2 + 5x + 5

(3 + 2x - x^2) + (x^2 + 8x + 5) = 10x + 8

(3x - 4) - (5x + 2) = -2x - 6

(2x^2 + 5x + 3) - (x^2 - 2x + 3) = x^2 + 7x

(3x^2 + 2x - 5) - (2x^2 - x - 4) = x^2 + 3x - 1

Third Question:

17x + 2y

(5x + 12y) + (3x + y) = 8x + 13y

17x - 8x = 9x

2y - 13y = -11y

Answer: 9x - 11y
