Step-by-step explanation:
What is a triangle?
A triangle is a polygon with three edges and three vertices. It is one of the basic shapes in geometry. A triangle with vertices A, B, and C is denoted.
Basic rule:
A triangle must be tri-sided, means it must have three sides which is only possible if the sum of the smaller two sides is greater than the third side. Otherwise, a triangle is not physically possible.
A- 2+3 = 5 hence not a triangle.
B- 3+7 > 9 hence a triangle.
C- 4+5 < 9.5 hence not a triangle.
D- 5+6 < 12 hence not a triangle.
Answer:
I think its x not = 4 because that would make the denominator = 0 after the multiplication. (g x h = 2x - 8 / x - 4
Step-by-step explanation:
Answer:
Step-by-step explanation:
We can see the fractions 
and 
of cups.
It can be seen that denominator has 4 i.e. the fraction 
.
Let us suppose, a unit is equal to 
of a cup.
Susan was supposed to use of a cup.
i.e. 5 units of butter was to be used.
But, actual recipe has only 3 units of butter.
a. 
Alternatively, we could have directly divided the given fractions:
Answer:
1. is 0.9 or 9/10. 2. is 43/36 or 1.19
