The height for substitution is 78
Answer:
5040
Step-by-step explanation:
All the possible Numbers that can be placed in the last for places =0,1,2,3,4,5,6,7,8,9
If all the digits have be different , then
=<u> 10</u> x <u>9</u> x <u>8</u> x <u>7</u>
= 90 x 56
= 5040 are total no. of 4-digit numbers can be made using those 4 digits.
1. x = 3, y = 2
2. x = -99/68, y = -14/17
3. x = -4, y = 1
4. x = 1, y = 5
5. x = -1, y = 0
6. x = 2, y = -3
7. x = 14, y = 20
I attached the pictures with the work.
Multiply base times height and your answer should be without decimals it would be 1,056 with decimals it would be 1.56. Hope this helps!
