Answer:
Actual height of the building is 37.5 feet
Step-by-step explanation:
Formula to be used to get the actual length of the building,
Scale used = 
= 
By this formula,
Actual height of the building = 1.25 × 30
= 37.5 feet
Therefore, actual height of the building will be 37.5 feet.
Answer:
72-b=p
Step-by-step explanation:
You start with 72, then take away the people bringing their own supplies (b), and that equals the number of people that will have supplies provided for them (p).
72-b=p
The answer is 36,000 because it is not over 36,500
You just do
3x=x+4
subtract x from both sides
2x=4
divide 2 from both sides
x=2
y=2+4
y=6
(x,y)= (2,6)
Y^2+5y the greatest common factor is y so
y(y+5)
...
4x^2-49 this is a "difference of perfect squares" which always factors to:
(a^2-b^2)=(a-b)(a+b), in this case:
(2x-7)(2x+7)
...
5s^2-20 GCF is 5
5(s^2-4) now the parenthetic term is a difference of squares so
5(s-2)(s+2)
