If four coordinates are given then:-
- Find length of the sides using distance formula
- Now break down into two triangles .
- Use herons formula and find areas of the triangles .add them and get the area
The property which states that multiplying a number by 1 does not change the number's value is the identity property. <span>Adding zero to a number does not change the number's value is the zero property, but some people do also call it the identity property of addition. Hope this helped!</span>
Answer:
55/36
Step-by-step explanation:
Step 1 mix value
3 x 3 = 9
9 + 2 = 11
2 x 5 = 10
10 + 2 = 12
Step 2 finding an equal denominator
36
Step 3 dividing
11/3 / 12/5
answer
55/36
Answer:
2(x - 7)(x + 2)
Step-by-step explanation:
Given
2x² - 10x - 28 ← factor out 2 from each term
= 2(x² - 5x - 14) ← factor the quadratic
Consider the factors of the constant term (- 14) which sum to give the coefficient of the x- term (- 5)
The factors are - 7 and + 2 , since
- 7 × 2 = - 14 and - 7 + 2 = - 5 , thus
x² - 5x - 14 = (x - 7)(x + 2) and
2x² - 10x - 28 = 2(x - 7)(x + 2)
