Answer: 
Step-by-step explanation:
According to the information provided in the exercise, the prices of each item he wants to purchase in the sporting goods store are:

Therefore you need to add these prices to solve this exercise. The sum will be the total cost for these three items.
You get that the sum is:

Then, the three items that Cisco wants to purchase will cost $73.43.
The answer is A,E,G,L,D,and H.
You can check this by doing this:
This is for A
16*4=84
12*7=64
84+64=148
We have the equation y = 12x. And we know the value of x. The value of x is 3.
So, if we replace the x variable with the value of x, then we can solve the equation.
y = 12(3)
y = 36
So, the answer is 36.
Answer:
31 1/2, or answer D
Step-by-step explanation:
Because you have three countertops which all have an area of 10 1/2 meaning you multiply 10.5x3 getting 31.5
Answer:
<h2><em>
2x-4</em></h2>
Step-by-step explanation:
Area of a rectangle = Length * Width
Given parameters
Area A = 8x2 – 10x – 12
Length of the rectangle = 4x+3
Required
Width of the rectangle.
Substituting the given parameters into the formula
8x2 – 10x – 12 = (4x+3)*width
width = 8x2 – 10x – 12
/4x+3
S
Factorizing the numerator
8x² – 10x – 12
= 2(4x²-5x-6)
= 2(4x²-8x+3x-6)
= 2(4x(x-2)+3(x-2))
= 2(4x+3)(x-2)
Width = 2(4x+3)(x-2)/4x+3
Width = 2(x-2)
Width = 2x-4
<em>Hence the width of the rectangle is 2x-4</em>
