Answer: 2x + y
<u>Step-by-step explanation:</u>
logₐ(3) = x
logₐ(5) = y
logₐ(45) = logₐ(3²· 5)
= logₐ(3)² + logₐ(5)
= 2 logₐ(3) + logₐ(5)
= 2 x + y <em>substituted given values (stated above)</em>
Use the Pythagorean theorem
a^2 + b^2 = c^2
a^2 + 15^2 = 25^2
a^2 + 225 = 625
a^2 = 400
a = 20
Answer: 20 cm

Answer:
(x, y, z) =(1, -1,2)
Step-by-step explanation:
.............
14.36 rounded to the nearest tenth is 14.4 (14.40).
Why?
Well because when rounding first we see what number we need to round. In this case it is 14.36 (3), next we look at the next number after the number which we need to round from which is 14..36 (6). If this number is 5 or MORE then we will round to the next number. But if it is LESS than 5 then we will keep it that number and add a 0 at the end. Since this number is AFTER 5 it will round up to 14.40.
So, 14.36 rounded to the nearest tenth is 14.40.
