Answer:
b = 40 and -40
Step-by-step explanation:
General form of Perfect square trinomial is a 2 + 2 a b + b 2
Therefore from 16 x 2 − b x + 25 a 2 = √ 16 x 2 , b 2 = 25 , then a = ± 4 x , b = ± 5 take consideration a=4x and b=-5 (different sign), then − b x = 2 ( 4 x ) ( − 5 ) − b x = − 40 x b = 40
The perfect square is ( 4 x − 5 ) 2 = 16 x 2 − 40 x + 25 .
if we consider a=4x and b=5 (same sign), then − b x = 2 ( 4 x ) ( 5 ) − b x = 40 x b = − 40
The perfect square is ( 4 x + 5 ) 2 = 16 x 2 + 40 x + 25 .
The first solution ( 4 x − 5 ) 2 is the best solution after comparing the expression given. I hope this helps, xx .
Answer:
Vector is 32 years old.
Step-by-step explanation:
As it is given that Mags is 34 years old and he is 2 years older than Vector.
Since Mags is 2 years older than Vector, Vector's age is 2 year less than Mags.
therefore we subtract 2 years from the age of Mags.
= 34 - 2 = 32 years
So Vector is 32 years old.
Answer:
i think this is the answer:
d + (a+b+c)
X=3
Y=2
Use the "Guess and Check Method"
For example, I inputed 2 for X and found that it was too small to work for the second equation, so I put in 3. Then for Y, I input 2 because 3+2=5. I put 2 in to replace Y in the second equation (3x-y=7) to see that 9-2=7. Therefore, X=3 and Y=2
