B = 12 - a
Subtract a from both sides to isolate b, and you get the answer.
13+13+13+13=52, not 43 .
<span>43 is a prime number therefore the only two factors are 1 and itself, Technically, you can say that 21.5 multiplied by 2 would be 43.</span>
Answer:
DE = 14
Step-by-step explanation:
Since, DE is a Mid-segment of triangle ABC.
Therefore,
DE = 1/2 * AC
2 DE = AC
2(5x - 1) = 3x + 19
10x - 2 = 3x + 19
10x - 3x = 19 +2
7x = 21
x = 21/7
x = 3
DE = 5x - 1
DE = 5*3 - 1
DE = 15 - 1
DE = 14
