Factor out a GCF of 4, then you are left with perfect squares.
4(100-9x^2)
Factor what is left as a difference of perfect squares (the outside and inside terms from FOIL should cancel out which is why each parenthesis has a different sign
f(10+3x)(10-3x)
Answer:
Upper deck = $38
Goal View = $63
Sidelines = $88
Step-by-step explanation:
Represent
- Sidelines with S
- Goal-view with G
- Upper-deck with U
We have that:



Required
Solve for S, G and U
Substitute 25 + G for S in the second equation

Make G the subject


Substitute 25 + U for G in the third equation

Collect Like Terms



Substitute 38 for U in 


Substitute 63 for G in

Answer:
That slope is undefined
Step-by-step explanation:
x doesn't have an existing value, therefore it is undefined.
Answer: Capacity of Marshfield Stadium is 109,015 and capacity of Bowden is Bowden.
Step-by-step explanation:
Let x = Capacity of Marshfield Stadium.
y = Capacity of Bowden.
As per given, we have
x - y = 7,675 (i)
x+y = 210,355 (ii)
2x = 218030 (iii)

Put value of x in (i) , we get
109015 - y = 7675
⇒ y= 109015 - 7675
⇒ y= 101,340
Hence, capacity of Marshfield Stadium is 109,015 and capacity of Bowden is Bowden.
