Answer:
26+32=10v
add numbers
58=10v
10v=58
divide both sides by 10
v=5.8
There will be 6 vans needed
58/6=9.6
There will be 10 students in four vans, and 9 students in two vans.

Answer:
Length of the Rectangle = 10 inches
and Width = 25 inches
Step-by-step explanation:
Let the width of the rectangle = k inches
So, the Length of the rectangle = (3k - 5) inches
Perimeter = 70 inches
Now, Perimeter of the Rectangle = 2(Length + Width)
= 2 (k + (3k-5))
⇒ 2 (k + (3k-5)) = 70
or, 2(k + 3k -5) = 70 ⇒ 2(4k - 5) = 70
⇒ 8k - 10 = 70
or, 8k = 70+ 10 = 80
or, k = 80/8 = 10
So, the Length = 10 inches
Hence, Width = 3k - 5 = 3(10) - 5 = 30 - 5 = 25 inches
So, Length of the Rectangle = 10 inches
and Width = 25 inches
Answer:
<em>Axis of Symmetry: x = -4 </em>
<em>Vertex: ( -4, -6 )</em>
Step-by-step explanation:
~ Part I ~
1. To find the axis of symmetry, rewrite y = x^2 + 8x + 10 in the parabola standard form ( 4p( y - k ) = ( x - h) ^2 for an up-down facing parabola at vertex ( h, k ) and a focal length |p|) ⇒ 4 * 1/4 ( y - ( - 6 ) ) = ( x - ( - 4 ) )^2
2. Therefore the parabola properties are ⇒ ( h, k ) = ( - 4, -6 ), p = 1/4
3. <em>Answer: x = -4</em>
~ Part II ~
1. From the previous question, we got that the vertex should be ⇒ ( -4, -6 )
2. <em>Answer: ( -4, -6 )</em>
