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>
Answer:
x4
Step-by-step explanation:
Answer:
The required option are
Length = 4 and width = x+5
Length = 2 and width = 2x+10
Step-by-step explanation:
Area of the rectangle = Length × width
Given
Area = 4x+20
Factoring out the common terms
Area = 4x + 4(5)
Area = 4(x+5)
Length = 4 and width = x+5
This can also be written as
Area = 2(2x+10)
Length = 2 and width =2x+10
