Answer:
A = 1/2(y2-y1) (x3-x1)
A = 21 units^2
Step-by-step explanation:
The area of a triangle is 1/2 bh
Using the left side as the base b= 6 units
This is found by taking (y2-y1)
The height is 7 units, counting from the left side to x3
This is found by taking (x3-x1)
A = 1/2(y2-y1) (x3-x1)
A = 1/2 (6*7)
A = 1/2 *42
A = 21 units^2
Answer:
The answer would be 21.248 miles
Answer:
0=0
Step-by-step explanation:
In step two. If we look on the left side of the equation in the first step, it reads 4(2x-4). When a number is multiplying an expression in brackets, we have to multiply every term in the brackets by the number in front of the brackets. In this case, it would be 4*2x + 4*(-4), which is 8x - 16. So the correct option would be the second (8x-16=16+2x) (the right side of the eqtn was 8+2x+8 and if we combine like terms we get 16+2x)
