Answer:
<h2>
</h2>
Step-by-step explanation:
w = yh - 2yc³
First of all factorize y out of the expression on the right side of the equation
That's
w = y( h - 2c³)
Next divide both sides by (h - 2c³) to make y stand alone
We have
<h3>
</h3>
We have the final answer as
<h3>
</h3>

Answer:
10 ft
Step-by-step explanation:
The length of the slide can be determined using Pythagoras theorem
The Pythagoras theorem : a² + b² = c²
where a = length
b = base
c = hypotenuse
6² + 8² =
36 + 64 = 100
c = √100
c = 10

Answer:
5.5
Step-by-step explanation:
1, 2, 5, 5, 6, 8, 9, 9
5+6=11
11 divided by 2= 5.5
Answer:
a + b + c + d + e = 180.
Step-by-step explanation:
We can prove that a = angle CBA (vertically opposite angles are equal).
Now, since lines DE and CA are parallel, then it follows that c = angle ACE (alternate angles are equal). Similarly, b = angle CAD.
But notice that what we've just done is found the angles of the triangle CBA.
So the sum of the angles (a + b + c + d + e) is the sum of the angles of a triangle.
We then conclude that a + b + c + d + e = 180 degrees.
