Reflection: the object is reflected (or "flipped") across a line of reflection, which might be the x-axis, y-axis, or some other line. Dilation: the object stays the same shape, but is either stretched to become larger (an "enlargement") or shrunk to become smaller (a "reduction").

Multiply the polynomials. (3 x2 + 3x + 5)(6x + 4)

miss Akunina [59]

= ( 3x² + 3x + 5 ) ( 6x + 4 )

= 18x³ + 18x² + 30x + 12x² + 12x + 20

= 18x³ + 30x² + 42x + 20

The volume of cylinder is 448 pie cm cube and height 7 cm find its radius

Verizon [17]

Answer:

$r =\bf 8 \space\ cm$

Step-by-step explanation:

The formula for volume of a cylinder is as follows:

$\boxed{Volume = \pi r^2 h}$

where:

• r = radius (? cm)

• h = height (7 cm).

Substituting the values into the formula:
$448 \pi = \pi \times r^2 \times 7$

Now solve for $r$ :

⇒ $r^2 = \frac{448 \pi }{\pi \times 7}$

⇒ $r = \sqrt{64}$

⇒ $r =\bf 8 \space\ cm$

Analyze the diagram below and complete the instructions that follow.

Jlenok [28]

Step-by-step explanation:

$scale \: factor = \frac{7}{28} = \frac{1}{4} \\$

$ratio \:of \:surface \:areas\\=\frac{2[5\times 7 + 7\times 3+3\times 5]}{2[20\times 28+ 28\times 12+12\times 20] }\\\\=\frac{[35 + 21+15]}{[560+ 336+240] }\\\\=\frac{71}{1136}\\\\=\frac{1}{16}\\\\= 1\: :\: 16$
