Answer:
The Area of Δ ABC = 219.13
Step-by-step explanation:
<em>The hard part about this problem is finding the area without the height</em>
The formula to do this is Area = 
A, B, C represent the sides
S represents  (A + B + C)
 (A + B + C)
In this equation, we will make the base be A, and the other two sides will be B and C
<u>Sides B and C are the same length</u> because they meet at a 90° angle
Lets plug the numbers into the variables
A = 28
B= 21
C= 21
<u>Remember:</u> S represents   (A + B + C)
  (A + B + C)
S =   (28 + 21 + 21)
 (28 + 21 + 21)
S =   (70)
 (70)
S = 35
<em>Lets plug the numbers into the Area Formula now!</em>
Area = 
According to the order of operations, we need to do the calculations in parentheses <u>first</u>
35 - 28 = 7
35 - 21 = 14
35 - 21 = 14
14 x 14 x 7 = 1372
1372 x 35 = 48020
 = 219.13
 = 219.13
The Area of Δ ABC = 219.13
 
        
             
        
        
        
Answer:
y = -x + 9.
Step-by-step explanation:
The slope = rise run
= 9 /-9
= -1.
The y intercept is at y = 9 so the equation is:
y = -x + 9.
 
        
             
        
        
        
I would personally have to say d it's not a or b though that's for sure
        
             
        
        
        
Yeah its gonna be 18 square feet in wide and length and the area is gonna be 36 square feet
        
             
        
        
        
Answer:
formula is width x height x length = volume
2x2x2=8
2 x 2 x 2 = 2 cubed so if you know a cube's side you just multiply it by itself twice
8 is the answer
