You have to subtract the 9 from both sides so 9-9=0 and 25-9= 16
then do 8/16 which = 2
so x=2

Answer:
h > 0, only integers
Step-by-step explanation:
One can only buy integer numbers of packages of hotdogs, so the domain is integer values.
Since we "must" buy more than 0 packages, the appropriate domain specification is ...
h > 0, only integers
Answer:
70
Step-by-step explanation:
<u>Basic Concept: Geometry</u>
<u>Formula:</u>
<u>Area of a polygon = </u><u></u>
where p = perimeter and a = apothem
In this problem we are given the area and the apothem and we need to find the perimeter
To do so we want to plug what we are given into the formula and solve for the missing piece.
We are given the area (350) and the apothem (10)
So in the formula we would plug in 350 for the area and 10 for "a"
We would then have
<u>Basic Concept: Algebra</u>
Now we use basic algebra to solve for p (perimeter)
step 1 multiply each side by 2
now we have 700 = 10p
Step 2 divide each side by 10
700/10=70
10p/10=p
we're left with p = 70
So we can conclude that the perimeter is equal to 70
Attic Floor: 8 m x 10 m = 80 m²
Roof: 3.5 m x 5 m x 10 m = 175 m²
You need 255 square meters (m²) of wood to build the roof and floor of the attic. I hope this helps, have a good night.
