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:
520 loaves
Step-by-step explanation:
First, let's find how many white loaves he baked.
Let's make a proportion.
white loaves/brown loaves= white loaves/brown loaves
He baked 3 white loaves for every 2 brown loaves. He baked x white loaves for 208 brown loaves.
3/2=x/208
Now, we have to solve for x. To do this, we have to get x by itself. x is being divided by 208. To reverse this, multiply both sides by 208
208*3/2=x/208*208
208*3/2=x
312=x
He baked 312 white loaves.
Now, we have to find the total number of loaves he baked.
To do this, add the brown loaves and the white loaves.
brown loaves+white loaves
He baked 208 brown loaves and 312 white loaves
208+312
520
He baked 520 loaves in total
Answer:
3
Step-by-step explanation:
To simplify this expression, we will simply work with the numerator, then the denominator, and then the fraction as a whole, following PEMDAS.
Numerator: 12 - 6 + 5 * (-3)^2
= 12 - 6 + 5 * (9)
= 12 - 6 + 45
= 6 + 45
= 51
Denominator: 17
So our simplified fraction is as follows:
51/17
Which can be reduced to the whole number, 3.
Cheers.
The polynomial that is a perfect square is 16x^2 + 24x +9. Option C shows the polynomial which is a perfect square.

What is square?</h3>
The square can be defined as a two-dimensional figure that has 4 equal sides.
Given are the equations of the areas of the polynomial.
Option C: 
We can write the above equation as,
Here a = 4x and b = 3, so
The simplification of the area of a polynomial is (4x+3)^2 which represents the area of a square.
Hence the polynomial that is a perfect square is 16x^2 + 24x +9. Option C shows the polynomial which is a perfect square.
