Maksim231197 [3]

Answer + Step-by-step explanation:

<u><em>your question is about equation 4</em></u> :

b_{1}=14-b_{2}

Then

\left( b_{1}\right)^{2}  =\left( 14-b_{2}\right)^{2}   \  \text{(this is a special product )}

Then

\left( b_{1}\right)^{2}  =14^{2}-2\times 14 \times b_{2}+ (b_2)^2

Then

\left( b_{1}\right)^{2}  =196-28 b_{2}+ (b_2)^2

A 99 ft length of wire is to be cut into 2 pieces, so that the longer piece is eight feet longer than six times the shorter piec
Serhud [2]

here's the solution,

let the length of shorter peice = x

then the lenght of longer peice = 6x + 8

now, we know that the sum of length of peices measures 99 feet,

So,

=》x + 6x + 8 = 99

=》7x = 91

=》x = 13

shorter piece length = 13 feet

longer peice length = 13 × 6 + 8 = 78 + 8 = 86 feet

The expression 6x2 gives the surface area of a cube, and the expression x3 gives the volume of a cube, where x is the length of
AVprozaik [17]

Answer:

surface area of the cube is 96m² and the volume is 64m³

Step-by-step explanation:

Surface area of the cube = 6x²

x is the side length

Given

x = 4metres

Surface area of the cube  = 6(4)²

Surface area of the cube = 6(16)

Surface area of the cube  = 96m²

Volume of the cube = x³

Volume of the cube = 4³

Volume of the cube = 64m³

Hence the surface area of the cube is 96m² and the volume is 64m³
