Answer:
x = 5
Step-by-step explanation:
Since we know that the diagonals bisect each other and divide into equal parts so ➡
x - 2 = 2x -7
2x - x = 7 - 2
x = 5
Answer:
Step-by-step explanation:
Prove: That the sum of the squares of 4 consecutive integers is an even integer.
An integer is a any directed number that has no decimal part or indivisible fractional part. Examples are: 4, 100, 0, -20,-100 etc.
Selecting 4 consecutive positive integers: 5, 6, 7, 8. Then;
= 25
= 36
= 49
= 64
The sum of the squares = 25 + 36 + 49 + 64
= 174
Also,
Selecting 4 consecutive negative integers: -10, -11, -12, -13. Then;
= 100
= 121
= 144
= 169
The sum of the squares = 100 + 121 + 144 + 169
= 534
Therefore, the sum of the squares of 4 consecutive integers is an even integer.
Answer:
The input of -1 is not allowed for the function.
Make 4 out of 10 a ratio, 4:10, so that means 40% of the population carry backpacks so 40% of 800 is 320, so I’m thinking it’s 320 students sorry if this is wrong
