yes
Step-by-step explanation:
y's can have the same x
Step-by-step explanation:
By Law of Indices, a^m * a^n = a^(m+n).
Therefore 8³ * 8⁵ = 8^(3+5) = 8⁸.
Answer:
(4a - 5)(4a + 5)
Step-by-step explanation:
Assuming you require to factor the expression
Given
16a² - 25 ← is a difference of squares and factors in general as
a² - b² = (a - b)(a + b)
16a² - 25
= (4a)² - 5²
= (4a - 5)(4a + 5) ← in factored form
We have that cos30=

by the definition of cos as the ratio of adjacent leg over the hypotenuse. Hence, 7/w=1/2 by eradicating square roots. Solving for w in this equation we get that w=7*2=14.
We have that the 3 sides obey the Pythagoran theorem, because:

Hence, the triangle is right. We also have that one side is half the hypotenuse hence one of the other angles of the triangle is 30 degrees because sin30=1/2. Finally, the third angle is 60 degrees because sum of angles=180.
Here, we have that sin 45=p/44=

. Multiplying by 44, we have that p=22
