Answer:

C)-2(9+32n)

Step-by-step explanation:

The given expresion is

$- 18 - 64n$

We can rewrite this expression as:

$- 2 \times 9 + - 2 \times 32n$

We factor -2 to obtain:

$- 2(9 + 32n)$

Note that, we can use the distributive property to obtain:

$- 2(9 + 32n) = - 18 - 64n$

Therefore the correct answer is C)-2(9+32n)

How to find the answers ?

maria [59]

AD || BC and BD is the transversal,

Therefore, angle DBC = angle ADB = 42° [alternate angles]

AD || BC and BD is the transversal,

angle BAD + angle ABD + angle DBC = 180° [co-interior angles]

or, 106°+ angle ABD + 42° = 180°

or, 148° + angle ABD = 180°

or, angle ABD = 180°-148° = 32°

Therefore, angle ABC = (32+42)° = 74°

AB||CD and BC is the transversal,

angle ABC + angle BCD = 180° [co-interior angles]

or, 72+2x+12 = 180

or, 84+2x = 180

or, 2x=180-84 = 96

or, x = 48

Answers: a)48°

b)42°

c)72°

Identify the "inside function" u = f(x) and the "outside function" y = g(u). Then find dy/dx using the Chain Rule.

skad [1K]

DfLet $f(x)=\sec x$ and $g(x)=\sqrt x$ . Then

$y=\sec\sqrt x=\sec(g(x))=f(g(x))=f\circ g(x)$

By the chain rule,

$\dfrac{\mathrm dy}{\mathrm dx}=\dfrac{\mathrm dy}{\mathrm du}\dfrac{\mathrm du}{\mathrm dx}$

where $u=g(x)=\sqrt x$ , so that $y=f(g(x))=f(u)=\sec u$ . We have

$\dfrac{\mathrm du}{\mathrm dx}=\dfrac1{2\sqrt x}$
$\dfrac{\mathrm d\sec u}{\mathrm du}=\sec u\tan u$

and so

$\dfrac{\mathrm dy}{\mathrm dx}=\sec u\tan u\dfrac{\mathrm dy}{\mathrm du}=\dfrac{\sec\sqrt x\,\tan\sqrt x}{2\sqrt x}$

Answer:

Step-by-step explanation:

The volume (V) of a rectangular prism is calculated as

V = length × width × height

Calculate the volume of each prism

Q → V = 8 × 4 × 5 = 60 ft³

R → V = 6 × 7 × 12 = 504 ft³

S → V = 4 × 10 × 12 = 480 ft³

T → V = 2 × 13 × 5 = 130 ft³

Prism R has the greatest volume → B
