A biologist was doing an experiment with plants. The shortest plant measured 13 feet. The tallest plant measured 1.45 feet. Drag

tekilochka [14]

The measurements that will be dragged into the box is 1.4 feet, 1.31 feet, 1.44 feet.

The rest of the measurement wouldn't be within the bounds and thus will not be dragged in.

A manufacturer of shipping boxes has a box shaped like a cube. The side length is

Tatiana [17]

The volume of a cube with side length equal to x, is $V= x^{3}$ ,

thus, the volume of a cube shaped box, whose side length is (5a+4b) is :

$V= (5a+4b)^{3}$ ,

The volume is already expressed in terms of a and b, but we can expand the expression $(5a+4b)^{3}$ , as follows:

$(5a+4b)^{3} =(5a+4b)(5a+4b)^{2}= (5a+4b)[ (5a)^{2}+2(5a)(4b)+ (4b)^{2}]$

$=(5a+4b)[ 25a^{2}+40ab+ 16b^{2}]$

$=(5a)[ 25a^{2}+40ab+ 16b^{2}]+(4b)[ 25a^{2}+40ab+ 16b^{2}]$

$=125a^{3}+200a^{2} b+ 80ab^{2}+100a^{2}b+160ab^{2} + 64b^{3}$

$125a^{3}+300a^{2} b+240ab^{2} + 64b^{3}$

Answer:

$V= (5a+4b)^{3}$ ,

or

$125a^{3}+300a^{2} b+240ab^{2} + 64b^{3}$

Determine an equivalent algebraic monomial expression using the laws of exponents. Show your work.

Serga [27]

The equivalent algebraic monomial expression of the expression given as (-8a^5b)(3ab^4) is -24a^6b^5

<h3>How to determine an equivalent algebraic monomial expression?</h3>

The expression is given as:

(-8a^5b)(3ab^4)

Multiply -8 and 3

So, we have:

(-8a^5b)(3ab^4) = (-24a^5b)(ab^4)

Multiply a^5 and a (a^5 * a = a^6)

So, we have:

(-8a^5b)(3ab^4) = (-24a^6b)(b^4)

Multiply b and b^4

So, we have:

(-8a^5b)(3ab^4) = -24a^6b^5

Hence, the equivalent algebraic monomial expression of the expression given as (-8a^5b)(3ab^4) is -24a^6b^5
