Answer:D
Step-by-step explanation:
If you see a zero in the end of a number it might be counting on by ten, the hint is most likely the zero. Let's say you had a question like: 10_30. If you see the zero, you can make sense out of it and try the tens times table. So add ten to 10 and bam! You found your answer
<span>You can use Heron's formula to solve this problem.
</span>

, where
A is the area;
a,b,с are the sides;
s<span> is the </span>semiperimeter<span> of the triangle
</span>

<span>According to conditions:
</span>a = x
b = x+1
с = 2x-1
<span>Calculate the semiperimeter:
</span>

<span>Now we can compose and solve the equation according to Heron's formula:
</span>

<span>As a result, x = 6 is your answer.
I hope this helped.</span>
<span>Use the explicit formula a</span>↓n=a↓1+(n-1)d to find the 1000th term of the sequence below. <span>24,31,38,45,52,..
a(1000) = 24 + 999*7 = 7017 Thus your answer is A</span>
$25-$18 would be $7 does this help?
