What Does The Scale Look Like?
My answer was $3.50. Can I have Brainliest for helping you when no one else wanted to?
Answer:
3
Step-by-step explanation:
a^2+b^2=9
(a+b)^2=9
finding the square root on both sides of the equation
a+b=3
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.
