Answer:
64
Step-by-step explanation:
The surface of the triangle count formula
A = b*h*1/2
A - area
b - base
c - height
The first triangle
A₁ = b₁*h = 6in * 8in *1/2= 24in²
The second triangle
A₂ b₂*h = 10in * 8in*1/2 = 40in²
The total area of the two triangles is 24in² + 40in² = 64 square inches

Answer:
D=-4<0, the equation has no real solutions, it has two imaginary solutions.
Step-by-step explanation:
The quadratic equation  has coefficients
 has coefficients 
a=1,
b=4, 
c=5.
The discriminant D is the expression 

Hence,

Since the discriminant is negative, the equation has no real solutions, it has two imaginary solutions.
 
        
                    
             
        
        
        
Answer:
x = 9
y = 6
Step-by-step explanation:
ΔABC ~ ΔPQR
Therefore, corresponding sides of these similar triangles will be in the proportional.



x = 
x = 9
Similarly, 
y = 
y = 6
