Answer:

= 5 ( 12d + 23f )

Step-by-step explanation:

-2(5d-9f)+7f-10(-9f-7d)

Open parenthesis

= -10d + 18f + 7f + 90f + 70d

Collect like terms

= -10d + 70d + 18f + 7f + 90f

= 60d + 115f

Factorise

= 5 ( 12d + 23f )

Therefore,

-2(5d-9f)+7f-10(-9f-7d) in its simplest form is 5 ( 12d + 23f )

How many different triangles can be constructed with three sides, each measuring 5 centimeters?
Akimi4 [234]
The first thing we will do is define an equilateral triangle:
 In geometry, an equilateral triangle is a regular polygon with three equal sides. In traditional Euclidean geometry, equilateral triangles are also equiangular, that is, the three internal angles are also congruent to each other, each angle with a value of 60 °
 Every equilateral triangle consists of three equal sides and three congruent angles.
 Therefore, there can be a triangle with three equal sides (5 centimeters in this case).
 Answer:
