Answer:

<h2> no, because the remainder is 126</h2>

Step-by-step explanation:

if x+3 is a factor, then -3 is a root of expression, and the remainder would be 0

calculating remainder:

$-3(-3)^3+6(-3)^2+6(-3)+9=-3\cdot(-27)+6\cdot9-18+9=\\\\=81+54-9=126$

determine (a) the volume and (b) the surface area of the three-dimensional figure. when appropriate, use pi key on your calculat

Answer:

$Volume = 150 yd^3$

$Surface Area = 150 yd^2$

Step-by-step explanation:

Going by the dimensions of the given three-dimensional figure, we can conclude that the figure is that of a cube. The height, length and width are equal.

Volume of a cube is given as $a^3$ , while surface area of a cube is given as $6a^2$

Where, a = the side length = 5 yards

$Volume = a^3 = 5^3$

$Volume = 150 yd^3$

$Surface Area = 6a^2 = 6(5)^2$

$Surface Area = 150 yd^2$

Use the figure to find y.

Vladimir79 [104]

Tanθ =sin /cos

tan θ = 5/2 / y

tan (30°) = 5/2 /y

$y = \frac{5 \sqrt{3} }{2}$

y=4.33
