The surface area of the rectangular prism can be found using the expression 6x exponent 3 + 4x exponent 2 + 12x. if the value of x is 3, what is the surface area, in square centimeters of the prism?

Answers

Answer 1

Answer:

Answer:

234 cm²

Step-by-step explanation:

Given expression to represent the surface area of the rectangular prism is $6x^(3) +4x^(2) +12x$

The given value of x is 3.

Now, finding value of expression by sustituting value of "x" as given.

Surface area of the rectangular prism = $6x^(3) +4x^(2) +12x$

Surface area of the rectangular prism= $6* 3^(3) +4* 3^(2) +12* 3$

∴ Surface area of the rectangular prism= $6* 27+ 4* 9+ 12* 3$

Surface area of the rectangular prism= $162+36+36= 234\ cm^(2)$

∴ Surface area of the rectangular prism= 234 cm²

What is the slope of the line for y = 1/2x + 2 and what is the y intercept of the line

Answers

Remember that the slope intercept formula is:

y = mx + b

m is the slope

b is the y-intercept

In this case m is 1/2 and b is 2.

This means that the slope of this line is 1/2 and the y-intercept is (0, 2) or simply 2

Hope this helped!

Answer:

see explanation

Step-by-step explanation:

The equation of a line in slope- intercept form is

y = mx + c ( m is the slope and c the y- intercept )

y = $(1)/(2)$ x + 2 ← is in slope- intercept form

with slope m = $(1)/(2)$ and y- intercept c = 2

Show or explain how to write 8,523 in expanded form using 15 hundreds

Answers

Answer:

7 thousands + 15 hundreds + 2 tens + 3 ones = 8523

Step-by-step explanation:

15 hundreds is equal to 1500, when subtracting that from the total of 8523, you get 7023 which still needs to be written in expanded form. The remainder can be written as the sum of:

7 thousands
2 tens
3 ones

Then adding the 15 hundreds that were given, will give a total 8523.

7,000 + 1,500 + 20 + 3 = 8,523
