(4x^4-x2-x)+(x^4+x^3+x^2+x-1)
=4x^4 - x2 - x + x^4 + x^3 + x^2 + x- 1
=5x^4 + x^3 - 1

(x^2 and x are canceled out)...
x^2 - x^2 = 0
x -x =0

Mathswatch Question! Mr Powers checks his electricity bill. Here are his meter readings. New reading: 6538 units, Old reading: 6

Setler79 [48]

Answer:

$Cost = 284 x$

Step-by-step explanation:

Given

$Old = 6245\ units$

$New = 6538\ units$

Required

The cost of units used

First, calculate the number of units used.

$Units = New - Old$

$Units = 6538 - 6254$

$Units = 284$

Next, multiply the units used by the cost per units,

Since the cost per unit is not given, we assume that it is x.

So, the total cost is:

$Cost = Units * Cost\ per\ units$

$Cost = 284 * x$

$Cost = 284 x$

6 The radius of the base of a cylinder is 39 in. and its height is 33 in.. Find the surface area of the cylinder in terms of s.

Delvig [45]

Answer:

17650 in².

Step-by-step explanation:

Given that the base of cylinder is 39 inch and it's height is 33inches . We need to find the surface area of the cylinder . So we know the TSA of cylinder as ,

$\bf\implies TSA_{(cylinder)}= 2\pi r ( r + h ) \\\\\bf\implies TSA_{(cylinder)}= 2\pi 39 ( 39 + 33) in.^2\\\\\bf\implies TSA_{(cylinder)}= 2\times \dfrac{22}{7}\times 39 \times 72 \\\\\sf:\implies \boxed{\red{\bf TSA_{(cylinder)}= 17650 in^2}}$
