Answer=9
To solve this, we just have to find a number that, when added to -4, make a total of 5, and when multiplied by -4 make a total of -36.
x+-4=5
x*-4=-36
9 fits the parameters for both of these
9+-4=9
9-4=5
5=5
9*-4=36
36=36
Answer:
No.
Step-by-step explanation:
If these sides come out true in the Pythagorean Theorem, then it is a right triangle.
a² + b² = c²
56² + 80² = 100²
3136 + 6400 = 10000
9536 ≠ 10000
Since these values do not come out true in the Pythagorean Theorem, it is not a right triangle.

Answer:
234 times
Step-by-step explanation:
<u>Number of times the number 7 appears in a hundred</u>
7 as units digit (07-17-27 ..... 97): 10 times
7 as tens digit (70-71-72..... 79): 10 times
20 times the digit 7 appears in first one hundred (0-100)
Let's calculate how many times 7 would be as units or tens in 7 hundreds
20X7 = 140 times digit 7 appears until number 699
<u>Now, from 700 to 777</u>
7 as hundreds digit (700-701-702 .... 777): 78 times
7 as tens digit (770-771-772 .... 777): 8 times
7 as units digit (707-717-727....777): 8 times
78 + 8 + 8 = 94 times the digit 7 appears in the range 700 - 777. Plus 140 times
140 + 94 = 234 times
