The lengths of two sides of a triangle are 7.8 cm and 5.6 cm. Between what two measures should the length of the third side fall
zloy xaker [14]

Hello! To draw a triangle, first, we have to follow a condition of existence.

This rule is:

• one of the sides must be ,bigger, ,than the absolute value, of the ,difference between the other two, sides

• the unknown side must be ,smaller ,than the ,sum of the other, two sides.

Let's write these rules using a, b, and c for the sides:

Considering a = 7.8 and b = 5.6:

[tex]\begin{gathered} |a-b|So, the third side must be smaller than 13.4 and bigger than 2.2.

3e-4=6e(45+2e) what's e
Lyrx [107]

Answer:

​  Rearrange the equation by subtracting what is to the right of the equal sign from both sides of the equation :

                    3*e-4-(6*e*(45+2*e))=0  

Step by step solution :

STEP

1

:

Equation at the end of step 1

 (3e - 4) -  6e • (2e + 45)  = 0  

STEP

2

:

STEP

3

:

Pulling out like terms

3.1     Pull out like factors :

  -12e2 - 267e - 4  =   -1 • (12e2 + 267e + 4)  

Trying to factor by splitting the middle term

3.2     Factoring  12e2 + 267e + 4  

The first term is,  12e2  its coefficient is  12 .

The middle term is,  +267e  its coefficient is  267 .

The last term, "the constant", is  +4  

Step-1 : Multiply the coefficient of the first term by the constant   12 • 4 = 48  

Step-2 : Find two factors of  48  whose sum equals the coefficient of the middle term, which is   267 .

At the movies, you order 3 boxes of popcorn and a bottle of water. The cost of the bottle of water is $1.75. Your total cost is
anastassius [24]
X=cost of one box of popcorn.
we can suggest this equation:

3x+1.75=9.25

3x=9.25-1.75
3x=7.5
x=7.5/3
x=2.5

Answer: the equation to find the cost of one box of popcorn is 3x+1.75=9.25, and the cost of one box of popcorn is $2.5.
