Length - 51 = width
78 - 51 = 27
width = 27
Answer:
The correct option is;
B. The difference of 2 perfect squares
Step-by-step explanation:
Solving a quadratic equation using factoring involves finding the factors of the equation that would yield the result of the quadratic equation
In order to find the roots of the quadratic equation, then the result of the factoring must be equal to zero, in which case, the constant terms in the factors are the solutions of the quadratic equation in opposite sign.
For example, we have;
x² - 5² = 11
We subtract 11 from both sides to get;
x² - 5² - 11 = 11 - 11
x² - 36 = 0
x² - 6² = 0
(x - 6) × (x + 6) = 0
Therefore, x = 6 or -6 which are the opposite sign of the constant terms in the factor.
1) what law of exponent is being described in the given ?
y⁴ x y⁷ = y¹¹
<h3>Answer :- Product of Powers ✓ </h3>
- When numbers with the same base are multiplied, the power of the product is equal to the sum of the powers of the numbers.
- If 'a' is a non-zero integer, and 'm' and 'n' are whole numbers then, am × an = am+n.

2) what law of exponent is being described in the given ?
(m⁵n³)² = m²x^²n³x^²
<h3>Answer :- Power of a product ✓ </h3>
- We use the power of a product rule when there are more than one variables being multiplied together and raised to a power.
- The power of a product rule tells us that we can simplify a power of a power by multiplying the exponents and keeping the same base.

Answer: GCF = 5<u>To find GCF:
</u>
25 = 5 x 5
40 = 5 x 8
GCF ⇒ Find the common factors.
Here, there is only 5 that is common. So 5 is the GCF.
