Answer:

We'll solve that in parts.

The upper part is a right triangle that is 4 by (2 + 2 +6)

Area = (4 * 10) /2 = 20

The bottom of that figure is made of 3 parts.

A) a 2 by 2 right triangle. area equals  (2*2)/2 = 2

B) a 2 by 2 square whose area equals 2*2 = 4

C) a 6 by 2 right triangle whose area equals (6*2) / 2 = 6

Total Area = 20 + 2 + 4 + 6 = 32

Answer:

The area of the figure is 32 units² .

Step-by-step explanation:

You can seperate the figures. In this diagram, there 3 triangles and 1 square. Then you have to calculate the area for each shape :

1st triangle (small shape),

area =  \frac{1}{2}  \times base \times height

Let base = 2 units,

Let height = 2 units,

area =  \frac{1}{2}  \times 2 \times 2

area = 2 \:  \:  {units}^{2}

2nd triangle (medium shape),

Let base = 2 units,

Let height = 6 units,

area =  \frac{1}{2}  \times 2 \times 6

area = 6 \:  \:  {units}^{2}

3rd triangle (large shape),

Let base = 10 units,

Let height = 4 units,

area =  \frac{1}{2}  \times 10 \times 4

area = 20 \:  \:  {units}^{2}

Square,

area =base \times height

Let base = 2 units,

Let height = 2 units,

area = 2 \times 2

area = 4 \:  \:  {units}^{2}

Lastly, you have to add up all the area of the shapes :

area = 2 + 6 + 20 + 4

area = 32 \:  \:  {unit}^{2}

Factoring x2+5x-1

The first term is, x2 its coefficient is 1 .
The middle term is, +5x its coefficient is 5 .
The last term, "the constant", is -1

Step-1 : Multiply the coefficient of the first term by the constant 1 • -1 = -1

Step-2 : Find two factors of -1 whose sum equals the coefficient of the middle term, which is 5 .

-1 + 1 = 0

Conclusion : Trinomial can not be factored

Final result :

x2 + 5x - 1
This is what did but I not sure it's right?!
