Step-by-step explanation:
A rectangular prism has a length of 4.2 cm, a width of 5.8 cm, and a height of 9.6 cm. A similar prism has a length of 14.7 cm, a width of 20.3 cm, and a height of 33.6 cm.
The dimensions of the smaller prism are each multiplied by what factor to produce the corresponding dimensions of the larger prism?

Answer:
x=2
Step-by-step explanation:
(x+2)(x-6)= y
0 = x+2 0 = x-6
The zeros of the functions are at -2 and 6 using the zero product property
We know a parabola is symmetric so the vertex is 1/2 way between the zeros
(-2+6)/2 = 4/2 =2
The x coordinate of the vertex is at 2
<span>10x² + 20y² =200 / </span>÷ 200 ;
x^2 / 20 + y^2 / 10 = 1 ;
x^2 /
