Answer:
Area = 8 square ft
Step-by-step explanation:
Area of a rectangle = Length × width
suppose length = x
width = y
Here it is given that x = 3 y - 2
width is given as y = 2 ft
∴ x = 3 × 2 -2
x = 6 -2
x = 4
Area of rectangle = length × width
A = 4 × 2
= 8 square ft
Answer:
13% per pair of shoes
because if she 78% on 6 shoes you would divide 78 by 6 to find the percent she spent on one pair of shoes
Answer:

Step-by-step explanation:
we know that
The equation of a exponential growth function is equal to

where
y is the average annual salary
x is the number of years
r is the rate of change
a is the initial value
In this problem we have

substitute


For x=4 years

Area of a rectangle is length * width.
7ab * 2a is the same as 7(2) * a(a) * b
7 * 2 = 14
a * a = a²
b = b
Put it all together.
14a²b is your monomial.
8x would represent multiplying 8(people) times x(ticket cost) But you don't know how much the tickets cost per person so that's why it's x.
8x + 20 = 76
76-20=56
56÷8=7
x equals 7
