Answer:
B. √2^5
Step-by-step explanation:
(2^½. 2^¾)²
= 2¹ . 2^(1½)
= 2^(2½)
= 2^(5/2)
=√2^5
6)a
if we put n as the number of sides in a regular polygon, the formula to find the measure of each angle is

so the answer will be

they each measures 144 degrees
good luck
Answer:
42cm
Step-by-step explanation:
It's a rectangle so sides are 6, 6, 15, 15. Σs = 42.
Y = x
y = -2/3x + 5
x = -2/3x + 5
x + 2/3x = 5
3/3x + 2/3x = 5
5/3x = 5
x = 5 * 3/5
x = 15/5 reduces to 3
y = x
y = 3
so ur answer is (3,3)
