Answer: 13.8cm^2

Step-by-step explanation:

The area of a triangle can be calculated with the formula:

A_{(triangle)}=\frac{b*h}{2}

The base of the triangle is "b" and the height of the triangle is "h",

In the figure you can observe that the base and the height of the triangle are:

b=6.9cm\\h=4cm

Knowing these values, you can substitute them into A_{(triangle)}=\frac{b*h}{2}.

Therefore, the area of the triangle is:

A_{(triangle)}=\frac{(6.9cm)(4cm)}{2}

A_{(triangle)}=13.8cm^2

let the said number be x

Nineteeen less than 6 times a number;

6x - 19

equals; 16 more than the number; this is 16 + x

6x-x = 16 + 19

5x = 35

x = 35/5

x = 7

Point m is the midpoint of ab¯¯¯¯¯ . am=3x+3, and ab=8x−6. what is the length of am¯¯¯¯¯¯ ?
LuckyWell [14K]
As given m is a midpoint of ab. So am is half of ab.

So we can write

am =  \frac{ab}{2}

As given am = 3x+3 , ab = 8x - 6.

So 3x+3 = \frac{8x - 6}{2}

3x+3 =  \frac{2(4x - 3)}{2}

3x+3 = 4x - 3

3+3 = 4x - 3x


6 = x

So x = 6.

So length of am = 3x+3 = 3*6 + 3 = 21
