P(x) = x^2 + 4x
y = x^2 + 4x
use the formula (b/2)^2 to find the new c value
(4/2)^2 = 4
add 4 to both sides
y + 4= x^2 + 4x + 4
y + 4= (x+2)^2
y= (x+2)^2 - 4
Answer:
x = 6
Step-by-step explanation:
This shows that the angle being split is 90 degrees.
<em>We know that 32 degrees are already known so we can do </em><em>90 - 32 = 58</em>
Now we know that 58 is the angle of 9x + 4
9x + 4 = 58
Subtract 4 from both sides
9x = 54
Divide both sides by 9 to isolate x
x = 6
5-2y=3x divide one both sides
5-2y/3=x
Switch the sides
X=5-2y/3

Step-by-step explanation:
look at the picture !
she has to paint actually 6 rectangles :
the 3 tops of the 3 stairs.
and the 3 vertical front boards (the front of each step of the stairs).
what is the area of these rectangles ? summing up all 6 - that is the surface area to be painted.
each top rectangle is clearly
82×19 (19 cm deep) = 1558 cm²
each front board is
82×12 (12 cm high) = 984 cm²
so, in total we have
3×1558 + 3×984 = 4674 + 2952 = 7626 cm²
as surface area to be painted.
