Answer:

Step-by-step explanation:

Here we can solve this in 2 ways ,
Method 1 :

Here the bases are equal. So,

Method 2 :

Here the exponents are same. So,

Answer:
x2+16x=9 x 2 + 16 x = 9. To create a trinomial square on the left side of the equation, find a value that is equal to the square of half of b b . (b2)2=(8)2 ( b 2 ) 2 . x^2+16x+9=0

Answer:
4
Step-by-step explanation:
The cost for plan 1 will be ...
p1 = 10 +5x
The cost for plan 2 will be ...
p2 = 30
These costs are equal when ...
p1 = p2
10 +5x = 30
5x = 20 . . . . . . . . subtract 10
x = 4 . . . . . . . . . . . divide by 5
