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:
A is false (Y is far left of 0, so it is a negative. H is close to 0 so it is positive. Y is farther from zero, so it is bigger. For example, Y could be -7, and H could be 3. The sum of -7 and 3, would be -5.
B is false (E is on the left of 0 so it is negative. Y is on the left of zero so it is also negative. Negative divided by a negative is a positive )
C is false (H is positive and E is negative. Positive times a negative equals a negative.)
D is true (A is close to zero, so it is a small positive number. H is farther from zero, so it is a larger positive number. For example, A can be 2 and H can be 5. So, 3 - 5 would equal a negative.)
