Answer:

Here are the formulas

Cube/Rectangular Prism:

Volume = Length*width*height

Surface area = 2(wl+hl+hw)

Lateral area= Area of vertical faces

Base area = length*width

Regular hexagonal prism:

Volume : (3sqrt3/2)*a^2*h

Surface Area  = 6ah+3sqrt(3)a^2

lateral area: 6ah

base area = 3sqrt(3)s^2/2

Triangular prism

Volume: The volume of a triangular prism can be found by multiplying the base times the height.

Surface area: A triangular prism has three rectangular sides and two triangular faces. To find the area of the rectangular sides, use the formula A = lw, where A = area, l = length, and h = height. To find the area of the triangular faces, use the formula A = 1/2bh, where A = area, b = base, and h = height.

the sales tax in bill's state is 6%. bill bought a scion having a sales tax of $820. what was the cost of the car? round to the
polet [3.4K]
Since there is a sales tax of 6% which was equal to $820

Let the value be = x

6% of x = 820

(6/100)x = 820

0.06x = 820

x = 820/0.06

x = 13666.67

Value to the nearest dollar ≈ $13 666.67

Which of the following is equivalent to x/x^2-1 + 4/x^2-6x-7?
kkurt [141]

Answer:

x(x-7)+4(x-1)/(x-1)(x+1)(x-7)

Step-by-step explanation:

Given the expression x/x²-1 + 4/x²-6x-7

Factorize x²-6x-7

x²-6x-7

= x²-7x+x-7

= x(x-7)+1(x-7)

= (x+1)(x-7)

Replace back into the expression given

x/x²-1 + 4/x²-6x-7

= x/x²-1 + 4/ (x+1)(x-7)

= x/(x+1)(x-1) + 4/(x+1)(x-7)

Find the LCM

=  x(x-7)+4(x-1)/(x-1)(x+1)(x-7)

This gives the required expression
