<em>x = 2</em>
Step-by-step explanation:
<u>Exponential Equations</u>
Solve:

Separate each exponential:

Operating:

Multiplying by 5:

Rearranging:

Recall that:


Calling


Factoring:

There are two possible solutions:
y=25
y=-50
Since

y cannot be negative, thus:

The solution is:
x = 2
First, the factor pairs for 18 are:
1, 18
2, 9
3, 6
Since the middle term is -3, the two factors must be 3 apart. The only pair that is 3 values apart is 3, 6.
Since the middle value is negative, the larger number is negative. This means that the 6 is negative.
z = -6
z = 3
Set each equal to 0;
z = -6
z + 6 = 0
z = 3
z - 3 =0
So your factors are (z+6) and (z-3), or answer B.
Answer:omg I gotchu I just learned these for the letters for example would be q/1 times 2/7 because if you have one letter or number you ALWAYS put a one under it then u multiply another easy trick don’t butterfly multiply go straight across and example 8/1 (all ways add the one) times 3/4. Ok how to multiply that always go across so it would be 8x3 and 1x4 your answer should be 24/4 and simplify if needed
