A number on its own is called a Constant.

A Coefficient is a number used to multiply a variable (4x means 4 times x, so 4 is a coefficient)

Answer:

Step-by-step explanation:

Triangle:

Base = 4 units

Height = 3 units {perpendicular height}

$Area=\frac{1}{2}*base*height\\\\=\frac{1}{2}*4*3\\\\=2*3$

= 6 square units

Rectangle:

To find the area count the number of squares. Number of square = 6

Area = 6 square units

or You can find the area of the rectangle as bellow also

Length = 3 units

Width = 2 units

Area = length*width

= 3*2

= 6 square units

Both the triangle and rectangles has the same area 6 square units

soldier1979 [14.2K]

Answer:

180 ways

Step-by-step explanation:

Aerospace companies (A) = 5

Energy development companies (D) = 3

Electronics companies (E) = 4

Number of aerospace stocks bought (a) = 2

Number of Energy development stocks bought (d) = 2

Number of Electronics stocks bought (e) = 2

The number of ways that the investor can select his six investments from the recommended list is given by the combination of picking two out five aerospace companies, multiplied by picking two out three energy development companies, multiplied by picking two out four electronics companies:

$n=\frac{5!}{(5-2)!2!}*\frac{3!}{(3-2)!2!}*\frac{4!}{(4-2)!2!}\\ n=10*3*6\\n=180\ ways$

There are 180 ways for the investor to select the six companies.
