Two figures are said to be congruent when they have the same shape and size or if one object is a mirror image of the other object. The sides AB and BC are congruent when they have equal lengths of the sides. An isosceles triangle two sides are equal in length.
Answer:
Step-by-step explanation:
I think you mean a^2 + 16a + 64.
The x-intercepts are the values of a for which the polynomial equals zero.
a^2 + 16a + 64 = (a+8)^2 = 0
a = 8
The x-intercept is 8.
Using arrangements of words, it is found that the statement is true.
------------------
- Suppose a word has n letters.
- Considering that m of these letters are repeating, each
times. - The number of distinct ways the word can be arranged is given by:

------------------
- The word "sleeplessness" has 13 letters.
- s repeats 5 times.
- e repeats 4 times.
- l repeats 2 times.
Thus, the number of ways to arrange the letters is given by:

------------------
- The word "senselessness" has 13 letters.
- s repeats 6 times.
- e repeats 4 times.
- n repeats 2 times.
Thus, the number of ways to arrange the letters is given by:

------------------
Finding the ratio of
to
:

Thus, since the ratio is 6, the statement is true.

Answer:
<h2>

</h2>
Step-by-step explanation:
<h3>to understand this</h3><h3>you need to know about</h3>
- area of triangles
- area of rectangle
- PEMDAS
<h3>tips and formulas:</h3>
- rectangle opposite sides are equal
- area of rectangle:l×w
- area of triangle:½×h×b
<h3>let's solve:</h3>
the area of the rectangle is
4×7 in²
28 in²
the area of above triangle is
½×6×7 in²
3×7 in²
21 in²
the area of left side triangle is
½×5×4 in²
2×5 in²
10 in²
therefore,
the area of the polygon is
28+21+10 in²
<h3>59 in²</h3>
Well fractions are set up over 100 so if it's 100% it would equal 100/100 or your answer, 1.
