Answer:

\huge\boxed{\sf 9x^2+12x+4 \ units^2}

Step-by-step explanation:

Given that,

Length of cube = l = 3x + 2 units

<h3><u>Base Area:</u></h3>

= l \times l\\\\= (3x+2)(3x+2)\\\\= 3x(3x+2)+2(3x+2)\\\\= 9x^2+6x+6x+4\\\\= 9x^2+12x+4 \ units^2\\\\\rule[225]{225}{2}

Which expression represents the height of the pyramid? StartFraction 3 V Over y squared EndFraction units (3 V minus y squared)
maxonik [38]

Answer:

Height = 3v/y² units

StartFraction 3 V Over y squared EndFraction units

Step-by-step explanation:

The volume of a solid right pyramid with a square base is v units3 and the length of the base edge is y units. which expression represents the height of the pyramid? units (3v – y2) units (v – 3y2) units units

Volume of a solid right pyramid = 1/3 × area of the base × height

Volume of a solid right pyramid = v units³

Area of the base = y² unit²

Volume of a solid right pyramid = 1/3 × area of the base × height

v = 1/3 × y² × height

Height = v ÷ 1/3 × y²

= v × 3/1y²

= (v × 3) / y²

= 3v / y²

Height = 3v/y² units

StartFraction 3 V Over y squared EndFraction units
