Given:
Denver can plant 3 rows of a certain length with 2 seedlings leftover or 4 rows of the same length with 3 seedling spots left empty.
To find:
The equation for the given problem and its solution.
Solution:
Let x be the length of each row.
Denver can plant 3 rows of a certain length with 2 seedlings leftover.
Total number of seeds he has = ...(i)
Denver can plant 4 rows of the same length with 3 seedling spots left empty.
Total number of seeds he has = ...(ii)
Using (i) and (ii), we get
Isolate variable terms.
Therefore, the required equation is and the values of x is 5. Each row is 5 meters long.
The volume of the given right triangular prism can be found by first calculating the area of the right triangle and then multiplying it with the length of the prism.
Let us find the area of the right triangle. As can be seen from the diagram the height, h of the right triangle is 7 cm and the base, b of the right triangle is 4 cm.
Therefore, the area of the triangle is:
Area=
Thus, the volume of the right triangular prism will be:
Volume=Area x Length of the prism
Volume=
Thus, out of the given options, option A is the correct option.
notice, the "common ratio" is -3, thus their sum is just
1 + (-3) + 9 + (-27) + 81.
