Answer:

b = 7 $\sqrt{3}$

Step-by-step explanation:

Since the triangle is right use the tangent ratio to solve for b

and the exact value

tan30° = $\frac{1}{\sqrt{3} }$ , thus

tan30° = $\frac{opposite}{adjacent}$ = $\frac{7}{b}$ and

$\frac{7}{b}$ = $\frac{1}{\sqrt{3} }$ ( cross- multiply )

b = 7 $\sqrt{3}$

How do I find the answer?

First simplify the number part, 14/2 = 7/1
then the x part, $\frac{x}{x^ \frac{3}{4} } = x^ \frac{1}{4} 
$
y doesn't need to be simplified
then simplify the z part, z^-6 = z^6

put it all together...
$7x^ \frac{1}{4}y^ \frac{1}{3} z^6$

The solution to 4p+2<2(p+5) is

gizmo_the_mogwai [7]

Answer:

p<4

Step-by-step explanation:

4p+2< 2(p+5)

Distribute: 4p+2<2p+10

Subtract 2 from both sides: 4p<2p+8

Subtract 2p from both sides: 2p<8

Divide and we get: p<4
