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.
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

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 .
Step-by-step explanation:
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.
