Answer:
first is 4^2 (add powers)
Second is a^(m-n) (subtract powers)
1.25 + 0.75x = 5.45 <== ur equation
0.75x = 5.45 - 1.25
0.75x = 4.20
x = 4.20 / 0.75
x = 5.6.....the maximum number of snacks he can buy is 5 <==
Equations are statements that have equal values, when compared
The true statement about
are x = 1 and x = -11
<h3>How to determine the true statement</h3>
The equation is given as:

Rewrite as:

Expand

Factorize

Factor out x + 11

Solve for x
x = 1 or x = -11
Hence, the true statement about
are x = 1 and x = -11
