Area of a triangle = 1/2 * (base * height)
Base = 9.9 cm
Height = 4.9 cm
So, Area of Δ = 1 / 2 * (9.9 * 4.9)
Area of Δ = 1 / 2 * (48.51)
Area of Δ = 48.51 / 2
Area of Δ = 24.3 cm²

Perimeter = total distance round the Δ
Perimeter = a + b + c
Perimeter = 5.26 + 9.37 + 9.9
Perimeter = 24.53 cm

The type of triangle here is Scalene because all the sides are not equal. Therefore, it is a Scalene triangle.

Factor completely x3 − 2x2 − 5x + 10.

Akimi4 [234]

Answer:

(x-2) (x^2 -5)

Step-by-step explanation:

x^3 − 2x^2 − 5x + 10

We will factor by grouping

Take and x^2 out of the first two terms and -5 out of the last two terms

x^2 (x-2) -5(x-2)

Now we can factor out (x-2)

(x-2) (x^2 -5)

How do you write this in standard form? (6-7i)/(1-2i)

xenn [34]

$\frac { \left( 6-7i \right) }{ \left( 1-2i \right) } \cdot 1\\ \\ =\frac { \left( 6-7i \right) }{ \left( 1-2i \right) } \cdot \frac { \left( 1+2i \right) }{ \left( 1+2i \right) } \\ \\ =\frac { 6+12i-7i-14{ i }^{ 2 } }{ 1+2i-2i-4{ i }^{ 2 } }$

$\\ \\ =\frac { 6+5i-14\left( -1 \right) }{ 1-4\left( -1 \right) } \\ \\ =\frac { 6+5i+14 }{ 1+4 } \\ \\ =\frac { 20+5i }{ 5 } \\ \\ =\frac { 20 }{ 5 } +\frac { 5i }{ 5 } \\ \\ =4+i$
