Answer:

3x + 5x - 4 = 1

Step-by-step explanation:

Given the equation

3x + y = 1

We must substitute the following equation:

y + 4 = 5x

So first we'll isolate y from the second equation so that then we can substitute its solution in the first equation:

y + 4 - 4 = 5x - 4

y = 5x - 4

Now we can substitute y in the first equation:

3x + y = 1

3x + 5x - 4 = 1

Solve the second equation for y so that you can substitute it in for y in the first equation..

y = 5x - 4

Substitute:

3x + (5x - 4) = 1

Find the surface area of the prism formed by the net

Lunna [17]

ANSWER

$T.S.A=1960m^2$

EXPLANATION

The diagram represents the net of a rectangular prism.

The dimensions are,

$l=42m$

$w = 14m$

and

$h = 7m$

The total surface area of a rectangular prism is given by:

$T.S.A=2(lw + lh + wh)$

We substitute the values to obtain,

$T.S.A=2(42 \times 14 + 42 \times 7 + 14 \times 7)$

$T.S.A=2(980)m^2$

$T.S.A=1960m^2$
