Answer:
D
Step-by-step explanation:
The equivalent expression to the given expression 25x²+16−40x−64y² are; (5x-4)²−64y² and (5x−4−8y)(5x+4+8y)
<h3>Difference of two squares</h3>
According to the question:
- We are required to determine the equivalent expression.
When we try to factorise the given expression systematically; we have;
- 25x²+16−40x−64y² = (25x²+16−40x)−64y²
By the difference of two squares concept;
Therefore, an equivalent expression is; (5x-4)²−64y²
Similarly, (5x-4)²−64y² is the difference of two squares and can be rewritten as; (5x−4−8y)(5x+4+8y)
Hence, we have the suggested expressions as equivalent expressions.

Answer:
the correct answer is HLI
Answer:
f(x) = -1.25(x) + 64
Step-by-step explanation:
Total = $80
Remove $4 + $12 = [$16] for food and entry which leaves us with $64.
For every ride, your friend would spend $1.25 which means that for every ride, you will subtract $1.25 from 64.
f(x) = 64 - 1.25(x) which is also f(x) = -1.25(x) + 64
