8⊕6 is 10
Step-by-step explanation:
We will use the substitution method to solve this problem
∵ The operation ⊕ is defined by p⊕q = 
∵ You want to find 8⊕6
- Then do these steps:
- Substitute p by 8
- Substitute q by 6
- Calculate the square root of 8² + 6²
∵ p = 8
∴ p² = 8² = 64
∵ q = 6
∴ q² = 6² = 36
∵ p⊕q = 
- Substitute p by 8 and q by 6 in the rule above
∴ 8⊕6 = 
- Substitute 8² by 64 and 6² by 36
∴ 8⊕6 = 
∴ 8⊕6 = 
∵ 
∴ 8⊕6 = 10
8⊕6 is 10

Answer:
There are no values of P to make it true
Step-by-step explanation:
Answer:
Width = 7 cm
Length = 15 cm
Step-by-step explanation:
Let width = w
Length = w + 8
Area of rectangle = 105 sq. cm
length * breadth = 105
(w + 8)*w = 105
Use distributive property
w² + 8w = 105
w² + 8w - 105 = 0
Sum = 8
Product = -105
Factors = 15 , -7 {15 +(-7) = 8 & 15*(-7) = -105}
w² - 7m + 15m - 105 = 0
w(w - 7) + 15(m - 7) = 0
(w - 7)(w + 15) = 0
Ignore w + 15= 0 as measurements will not be in negative value
w - 7 = 0
w = 7
Width = 7 cm
Length = 7 + 8 = 15 cm
I would put the equation into two fractions to make a proportion.
30/24 = 20/x
From there, you'd cross multiply to get:
30x = 480
x = 16
So, if there are 20 children currently in the elevator, 16 adults can still enter.
