Answer:
0.05
Step-by-step explanation:
Given parameters:
The scaled height of the dog house = 6cm
Original height = 51inches
let us convert the original height to cm;
1in = 2.54cm
51in = 51 x 2.54 = 129.54cm
Scale factor;
= 
= 0.05
The scale factor is 0.05, the drawing has been reduced by a multiple of 0.05 of the actual height

Let
x-------> the first number
y-------> the second number
we know that
equation 1
equation 2
substitute the equation 1 in equation 2
![[-5-y]*y=-90 \\ -5y- y^{2} =-90 \\ y^{2} +5y-90=0](https://tex.z-dn.net/?f=%5B-5-y%5D%2Ay%3D-90%20%5C%5C%20-5y-%20y%5E%7B2%7D%20%3D-90%20%5C%5C%20y%5E%7B2%7D%20%2B5y-90%3D0)
using a graphical tool to resolve the second order equation
see the attached figure
the numbers are-12.3117.311
Answer: 2ab - e/3 - 3d
Step-by-step explanation:
2ab - 1/3e - 3d
= 2ab - 1e/3 - 3d
= 2ab - e/3 - 3d
