Answer:
Step-by-step explanation:
F(x) G(x)
Let x = width
x+1 is then the length
2x+2(x+1)=66
2x+2x+2=66
4x=64
x=16
deck will be 16x17, nice for a BBQ. :)

Answer: 138,240 cubic cm</h3>
Explanation:
If x is the side length of a cube, then x^3 is the volume. Think of it like length*width*height, but length = width = height.
It's no coincidence that the cubing operation or cubed exponent ties directly to the concept of things like volumes in cubic cm.
In this case, x = 12 cm is the side length of each small cube. The volume of each small cube is x^3 = 12^3 = 12*12*12 = 1728 cubic cm.
Eighty such small cubes get us a total volume of 80*1728 = 138,240 cubic cm.
Answer:

Step-by-step explanation:
Given the quadratic function

we have to find the leading coefficient of given quadratic equation.

The coefficient of
i.e a is known as the leading coefficient.
Comparing given equation with the standard equation, we get
a=-2

Answer:
Step-by-step explanation:
Parallel to y=2÷3x+6
Passes through (6,7)
slope is (2/3)
Solve for when y is 7 and x is 6.
take out the + 6 at the end because it doesnt change the slope. replace with b. (y=mx+b)
replace y and x.
7 = (2/3)(6)+b
solve for b and then put it back into the equatio and make 6 and 7 into x and y again.
