To solve this problem you must apply the proccedure shown below:
1- You have the following quadratic expression <span>n^2-25.
2. When you factor, you obtain:
(n-5)(n+5)
3. To verify this is true, you can apply the distributive property, as below:
</span><span>n^2+5n-5n-25
</span><span>n^2+25
Therefore, as you can see, the answer is the second option, which is:
(n-5)(n+5)</span>
First find x:
3x + 41 + x + x-8 + 2 = 100
Simplify :
5x + 35 = 100
Subtract 35 from both sides:
5x = 65
Divide both sides by 5:
X = 13
Total British stamps = x + x-8 = 13 + 13-8 = 18
Probability of being British = 18/100 = 9/50 as a fraction.
If sum of numbers (a) +(b) is 1419 and
(a) and (b) are <span>neighbors , whe have:
a + b = 1419 and b-a = 1;
<=> </span>a + b = 1419 and <span>a = b-1 ;
so we have b-1 + b = 1419 <=> 2b = 1420 <=> b=710 and a = 709
Answer: 710 and 709

Answer:
(x-4)2=-13
Step-by-step explanation:
2x+13=8
2x-8=-13
