The variable “x” can be defined as the price of regular gas.
The equation is x = x - (.02)7
x = x - (.02)7
(.02)7 = .14
x = x - .14
X - X = nothing so it just leaves you with -.14
The answer is that the gas price changed by a total of - 14 cents or -0.14
Answer:
x(x + 4) = 21
Step-by-step explanation:
Area = length * width.
21 = x + 4 * x
x(x + 4) = 21
Check the picture below, so let's check the equations below hmmm

Answer:
Step-by-step explanation:
A)
Dilation. Since it's only the size of the figure that's changing
B)
Height of the smaller one: 4
Width of the smaller one: 6
Height of the bigger one: 6
Width of the bigger one: 9
6/4 = 1.5
9/6 = 1.5
Since both 6/4 and 9/6 was 1.5, that means that the Width and Height was proportional and that the two trapezoids is at a ratio o:
1 : 1.5
One unit of the smaller one is 1.5 units on the bigger one.
