No triangle 60+40=100 which is the same as one side
The question requires that the four lines that intersect form a parallelogram but not an specific parallelogram, so you are not restricted by a diagram.
You can use these equations for the four lines:
1) y = 0 (it is the x-axis)
2) y = 4 (it is a line parallel to the x-axis, whose y-intercept is 4.
3) y = x (it is an inclined line that intersects both y = 0 and y = 4 lines.
4) y = x + 7 (it is a line parallel to y = x, that also intersect the both y = 0 and y = 4 lines.
Answer: D) (2,0)
Step-by-step explanation:
These are your values.

Remember this means;

The formula for finding the midpoint of a segment is simple. Add both x's and y's and divide them by 2 separately. Or, if you like to follow formulas, here you go.
Let M be midpoint.





Answer:
i. x^2 – 1
ii. x^3 – 1
iii. x^4 - 1
Step-by-step explanation:
Products are obtained by multipliyng each left term by each rigth term as follows:
i. (x- 1)(x+ 1) = (x^2 – x + x - 1) = x^2 – 1 (equal terms with opposite sign substracts and the result is 0)
ii. (x- 1)(x^2 + x + 1) = (x^3 – x^2 + x^2 – x + x – 1) = x^3 – 1
iii. (x- 1)(x³ + x² + x + 1) = (x^4 – x^3 + x^3 – x^2 + x^2 – x + x – 1) = x^4 - 1
