Answer:
Area- 22.5
Step-by-step explanation:
To find the area in a triangle you will want to multiple the base with the height then divide it by two. in this photo you have two options 9X5/2 or 7.5X6/2
remember- a= 1/2 b X h
 
        
             
        
        
        
Answer:
Step-by-step explanation:
hello : 
y-3=-2(x+5)
y - intercept  when : x=0 : y-3 =-2(0+5)
y-3 =-10
y = - 7

Answer:
x = -  , x = 3
, x = 3
Step-by-step explanation:
Given
(4x - 5)² = 49 ( take the square root of both sides )
4x - 5 = ±  = ± 7 ( add 5 to both sides )
 = ± 7 ( add 5 to both sides )
4x = 5 ± 7, thus
4x = 5 - 7 = - 2 ( divide both sides by 4 )
x =  = -
 = - 
or 
4x = 5 + 7 = 12 ( divide both sides by 4 )
x = 3
As a check
Substitute these values into the left side of the equation and if equal to the right side then they are the solutions.
x = - 
left side = (- 2 - 5)² = (- 7)² = 49 = right side ⇒ solution
x = 3
left side = (12 - 5)² = 7² = 49 = right side ⇒ solution
