Evaluate the power 3600-6.3 x 100, then your gonna want to multiply the numbers 3600-630 , once you subtract the numbers your answer will be 2970
Answer:
They are the similar because 2 of their angles are identical and that means that the third angles have to be the same also.
<u><em>Commutative:</em></u>
93 + (68 + 7) ⇒ (68 + 7) + 93
<u><em>Associative:</em></u>
93 + (68 + 7) ⇒ (93 + 68) + 7
<u><em>Identity:</em></u>
93 + (68 + 7) + 0 ⇒ 93 + (68 + 7)
Answer:
(y - 5)(y + 4)
Step-by-step explanation:
Given
y² - y - 20
Consider the factors of the constant term (- 20) which sum to give the coefficient of the y- term (- 1)
The factors are - 5 and + 4, since
- 5 × 4 = - 20 and - 5 + 4 = - 1, thus
y² - y - 20 = (y - 5)(y + 4) ← in factored form
4ˣ⁻¹ = 49 / 4
<h3>How to simplify an expression?</h3>
The expressions can be simplified as follows;
Hence,
Therefore,
Finally,
2ˣ = 7
4ˣ⁻¹ = 2²⁽ˣ⁻¹⁾ = 2²ˣ ⁻ ² = 2²ˣ / 2² = (2ˣ)² / 2²
Therefore,
(2ˣ)² / 2² = 7² / 2² = 49 / 4
Hence,
4ˣ⁻¹ = 49 / 4
Finally, the is equal to and for the second part 4ˣ⁻¹ = 49 / 4
