Answer: 2r2(6r3+14r2−30r+14)

Step-by-step explanation:

Apply the distributive property

2r2(6r3)+2r2(14r2)+2r2(−30r)+2r2⋅14

Simplify

2⋅6(r2r3)+2⋅14(r2r2)+2⋅−30(r2r)+28r2

Simplify each term

12r5+28r4−60r3+28r2

Answer:

<em>12 </em>r^{5}<em> + 28 </em>r^{4}<em> - 60 r³ + 28 r² </em>

Step-by-step explanation:

a(b ± c) = ab ± ac (distributive property)

a^{m} * a^{n} = a^{m+n}

2r²(6r³ + 14r² - 30r + 14) = <em>12 </em>r^{5}<em> + 28 </em>r^{4}<em> - 60 r³ + 28 r²</em>

Determine el área del siguiente rectángulo
Arte-miy333 [17]
English ⬇️

So, 8*8=64, and is expressed as 64 square feet. A square has all sides equal. So, since one side is 8 feet long the other sides also have the same length. Area of a rectangle is length multiplied by the width.

Answer?= 8

Spanish ⬇️

Entonces, 8 * 8 = 64, y se expresa como 64 pies cuadrados. Un cuadrado tiene todos los lados iguales. Entonces, dado que un lado mide 8 pies de largo, los otros lados también tienen la misma longitud. El área de un rectángulo es la longitud multiplicada por el ancho.

hola no puedo hablar español así que tuve que traducir espero que esto sea bueno y la respuesta es 8 ¡buena suerte!
