Use the properties of exponents to solve for each variable.
4^8•4^2=4a
(2^4)^5=2^b
5^6/5^2=5^c
a=
b=
c=

Step-by-step explanation:

1) 4^10 = 4^a

a = 10

2) 2^20 = 2^b

b = 20

3)5^4 = 5^c

c = 4

to find the perimeter of the rectangle this is the expression:

x-9+x-9+3x-4+3x-4=138

if we simplify it:

8x-26=138

remember, 138 is what it all adds up to

the length is 11.5cm

the width is 57.5cm

the area is 661.25cm^2

the answers might not be correct use at own risk

9 sandwiches per hour

step-by-step explanation:

when we have a rate, we want a 1 in the denominator

27/3 = 9

27 sandwiches/ 3 hours = 9 sandwiches/hour
