Answer:

Point B is (-1,2)

Step-by-step explanation:

Given: A triangle ABC was rotated 90 degrees counterclockwise

To find: coordinates of the point B

Solution:

A triangle is three - dimensional figure that has three sides, three vertices and three angles.

Counterclockwise refers to the direction opposite to the direction of movement of hands of the clock.

As triangle ABC was rotated 90 degrees counterclockwise about the origin, point B is (-1,2)

2. 24

3. \frac{1}{12}

4. \frac{1}{8}

5. 15

6. \frac{1}{15}

Step-by-step explanation:

1. 4÷ \frac{1}{8} = 4*8=32

2. 6÷\frac{1}{4} = 6*4=24

3. \frac{1}{3}÷4=\frac{1}{3}*\frac{1}{4} =\frac{1}{12}

4. \frac{1}{2}÷4=\frac{1}{2} *\frac{1}{4} =\frac{1}{8}

5. 5÷\frac{1}{3} =5*3=15

6. \frac{1}3}÷5=\frac{1}{3} *\frac{1}{5} = \frac{1}{15}

What is the width of the rectangle shown below? <br>4x + 3 <br>A = 8x2 – 10x – 12
ozzi

Answer:

<h2><em>2x-4</em></h2>

Step-by-step explanation:

Area of a rectangle = Length * Width

Given parameters

Area A = 8x2 – 10x – 12

Length of the rectangle = 4x+3

Required

Width of the rectangle.

Substituting the given parameters into the formula

8x2 – 10x – 12  = (4x+3)*width

width = 8x2 – 10x – 12 /4x+3

S

Factorizing the numerator

8x² – 10x – 12

= 2(4x²-5x-6)

= 2(4x²-8x+3x-6)

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

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

Width = 2(4x+3)(x-2)/4x+3

Width = 2(x-2)

Width = 2x-4

<em>Hence the width of the rectangle is 2x-4</em>
