<h2>Perfect Squares</h2>
Perfect square formula/rules:
Trinomials are often organized like .
The <em>b</em> value in this case is <em>c</em>, and it will always equal the square of half of the <em>b</em> value.
- Perfect square trinomial:
- or
We're given:
In a trinomial, we're given the and
values. <em>a</em> in this case is 1 and <em>b</em> in this case is 4. To find the third value by dividing 4 by 2 and squaring the quotient:
- 4 ÷ 2 = 2
- 2² = 4
Therefore, the term that we can add is + 4.
To write this as the square of a bracketed expression, we can follow the rule :
Answer:
The other legs are 9 and 9√3
Step-by-step explanation:
The longer side of a 30-60-90 degree rectangle is 18.
The other legs will be
and
Where x is the longest side, which is given as 18.
Therefore one leg will be:
and the other leg will be:
If two similar triangles have sides in the ratio a : b, then their areas are in the ratio a² : b².
We have the ratio:
Area of the smaler triangle = x
Area of the larger triangle = 567 cm²
Therefore we have the equation:
F(x) = (-x²+x+20) / (x+4)
-x²+x+20 | x+4
+x²+4x -x+5
\\\\ 5x+20
-5x-20
\\\\\\\\\
f(x) = (x+4)(-x+5) / (x+4)
f(x) = (-x+5)
The graph is a decreasing line, with origin from 5.
-x²+x+20 | x+4
+x²+4x -x+5

f(x) = (x+4)(-x+5) / (x+4)
f(x) = (-x+5)
The graph is a decreasing line, with origin from 5.
