Answer: 
Step-by-step explanation:
Using the data given in the exercise, we can draw the diagram attached, where "h" is the height of the building reached by the top of the ladder.
Notice that there are two similar triangles.
So, you can set up the following proportion:
Finally, in order to calculate the height on the building reached by the top of the ladder, you must solve for "h".
Therefore, the value of "h" is :
A polynomial with a degree of 2 can be:
x² + 1
y² + 2
etc..

1.6 divided by x =4
we can exchange the 4 and the x
1.6 divided by 4 =x
.4 =x
Standard form is Ax + By = C
Your equation is y = 3/4 x + 1
3/4 x + 1 y = 1
Grouping is when you have to terms that are the same inside the parenthesis and a different or same number outside the parenthesis and then the one inside the parenthesis u are going to group them not combined them and write them once and the numbers inside the parenthesis group them together by adding them and put parenthesis between them
Ex
5(4x+1)10(4x+1)
(5+10)(4x+1)
