Answer:
All parallelograms have at least 1 parallel side.(Rectangles,squares,rhombuses,etc.)Trapezoids also have parallel sides.
Step-by-step explanation:
Answer:

Step-by-step explanation:

Let's apply the formula (x+y)² = x² + 2xy + y²
Here, x = -a and y = b
So,
= (-a)² + 2(-a)(b) + (b)²
= a² - 2ab + b²
Hence, it has been proved that (-a + b)² = a² - 2ab + b².

Answer:
3
Step-by-step explanation:
D(1 , 1) to D'(3, 3)
so x (1 x 3)= 3
y (1 x 3) = 3
SF = 3
D(1 , 5) to D'(3, 15)
so x (1 x 3)= 3
y (5 x 3 ) = 15
SF = 3
Same on coordinate points B to B' and C to C'
so SF = 3
Answer:
The answer is
<h2>

</h2>
Step-by-step explanation:
To find the equation of a line given a point and slope we use the formula
<h3>y - y1 = m(x - x1)</h3>
where
m is the slope
( x1 , y1) is the point
From the question
Slope / m = - 2
The point is ( 10, - 9)
Substitute the values into the above formula
That's the final answer is
