Jack cuts four squares with side length X inches from corners by a 5" x 7" cardboard rectangle. He folds the remaining cardboard

viktelen [127]

Answer:

$V = x^3-24x^2+35x$

Step-by-step explanation:

Jack makes a cuboid. If the length is l, the width is w and the height is h, then its volume is

$V = lwh$

The height is determined by the side of the square cut out of each corner.

$h = x$

Along the length of the width, the length of two sides of the square are cut.

$l = 7 - 2x$

$w = 5 - 2x$

$V = lwh = (7-2x)(5-2x)(x)$

$V = x(35-24x+4x^2) = x(x^2-24x+35) = x^3-24x^2+35x$

Karin wants to use the distributive property to mentally find the value of 19 x 42+ 19x 58. Which expression can she use?

ipn [44]

19 x (42 + 58) or 19*(42 + 58) is the expression she can use. You factor out the common term 19. The distributive rule says that we can multiply the outer 19 with each term inside to get the original expression again.

PLEASE HELP ALGEBRA 2 Question is on the photo below

Sedbober [7]

Answer:

The value of f(x) - g(x) is:

f(x) - g(x) = 2x² + 6x - 4

Step-by-step explanation:

Given

f(x) = 3x² + x - 3

g(x) = x² - 5x + 1

To determine

f(x) - g(x)

Using the formula

f(x) - g(x) = 3x² + x - 3 - ( x² - 5x + 1)

= 3x² + x - 3 - x² + 5x - 1

= 2x² + 6x - 4

Therefore, the value of f(x) - g(x) is:

f(x) - g(x) = 2x² + 6x - 4
