Answer:
1800
is the area of parallelogram.
Step-by-step explanation:
Given that:
Area of a triangle = 900
To find:
Area of a parallelogram which has same height and base as that of the given triangle.
Solution:
First of all, let us have a look at the formula for Area of a parallelogram:
...... (1)
So as to find the area of a parallelogram, we need to have the product of Base and Height of Parallelogram.
Now, let us have a look at the formula for area of a triangle:

Given that height and base of triangle and parallelogram are equal to each other.
So,the product of base and height will also be equal to each other.

By equation (1):
<em>Area of parallelogram = 1800 </em>

Answer:
x = -2
Step-by-step explanation:
3x -8 =8x +4/2
3x -8 =8x +2
3x -3x -8 = 8x -3x +2 (subtract 3x both sides )
-8 = 5x +2
-8-2 =5x+2 -2 (subtract 2 both sides )
-10 =5x
-10/5 = 5x/5 (divide 5 both sides)
-2 = x
The retail price is $50 because 25% of 40 is 10 and 10+40=50.

Let us determine the product of 438 and 17 by partial products.
Consider 
and 
So, 

= 
= 7446
Therefore, the product of 438 and 17 is 7446.
No, Sandra's answer is not correct.
Because she should have expressed 17 as (10+7), then if she multiplied (438 by 10) and (438 by 7). And, then added the results.Then her answer would be correct.
