Question # 4
Sedbober [7]

Answer:

Brett  is 62 years old, Carl is 70 years old and Mark is 80 years old.

Step-by-step explanation:

let the age of Brett be <em>x</em> years.

thus the age of Mark is <em>(x+18)</em> years .

{as it is given that Brett is 18 years younger than Mark}

∴ Age of Carl is <em>(x+8) </em>years .

Now the sum of ages,

3x+26=212 (given)

3x=186

∴x=62

thus , the age of Brett is 62 years , the age of mark is <em>(x+18)</em>= 80 years and the age of Carl is <em>(x+8)</em>= 70 years

vekshin1

Answer:

106.5 square units.

Step-by-step explanation:

See the attached diagram.

The pentagon ABCDE consists of three triangles namely Δ ABC, Δ ACD, and Δ ADE when we join the diagonals AC and AD.

So, Area of Pentagon ABCDE = Area of  Δ ABC + Area of Δ ACD + Area of triangle Δ ADE.

⇒ Area of Pentagon ABCDE = (31.8 + 39.2 + 35.5) = 106.5 square units. (Answer)

azamat

Answer:

C

Step-by-step explanation:

The equation of a line in point- slope form is

y - b = m(x - a)

where m is the slope and (a, b) a point on the line

Here m = 3 and (a, b) = (2, - \frac{1}{2} ) , thus

y - (- \frac{1}{2} ) = 3(x - 2) , that is

y + \frac{1}{2} = 3(x - 2) → C
