Answer:
The vertex form parabola y = 2( x+4)² -37
Step-by-step explanation:
<u>Step(i):-</u>
Given parabola equation j(x) = 2x² + 8x -5
Let y = 2x² + 8x -5
⇒ y = 2(x² + 2(4x)+(4)²-(4)²) -5
By using (a + b)² = a² +2ab +b²
y = 2(x+4)²- 32 -5
y = 2 ( x-(-4))² -37
<u><em>Step(ii):-</em></u>
The vertex form parabola y = a( x-h)² +k
The vertex form parabola y = 2(x+4)² -37
Answer:
The width is 87 cm
Step-by-step explanation:
The area of a rectangle is given by
A = l*w
8613 = 99 * w
Divide each side by 99
8613 / 99 = 99 w /99
87 = w
The width is 87 cm
The answer is 9 because if you put those numbers in a life from smallest to biggest and take one off each side your left with 9
