Many points!! Answer asap
Semmy [17]
Remember
(ab)/c=a(b/c)
and
b/b=1 when b=b


1.
8+9t+4=
8+4+9t=
12+9t=
9t+12

2. (56ab)/b=56a(b/b)=56a(1)=56a

3. divising negatives yeilds positive

Simplify the expression.<br><br> 16(1/2x)^4<br> The simplified expression is
SVEN [57.7K]

Answer:

1/x^4

Steps:

(1/2x)^4 =  <em>1/2^4x^4</em>

= 16 *  1/2^4x^4

Multiply fractions: <em>a * b/c = a * b/c</em>

= 1 * 16/2^4x^4

Multiply the numbers:<em> 1 * 16 = 16</em>

16/2^4x^4

Factor 16: <em>2^4</em>

= 2^4/2^4x^4

Cancel the common factor: <em>2^4</em>

= 1/x^4

What is ...<br><br> 4x + 10= 2x - 6
Nata [24]
4x + 10= 2x - 6
Subtract 2x on both sides

4x - 2x + 10 = 2x - 2x - 6

4x - 2x + 10 = -6

2x + 10 = -6

Subtract 10 on both sides

2x + 10 - 10 = -6 - 10

2x = -6 - 10

2x = -16

x = -8

Find the exact value of sin A in simplest radical form.<br>​
Scorpion4ik [409]

Using the law of sines, we have

\dfrac{AB}{\sin(C)}=\dfrac{BC}{\sin(A)}

And we know that

AB=\sqrt{85},\quad BC=6,\quad A=90

So, the equation becomes

\sin(A)=\dfrac{BC\sin(C)}{AB}=\dfrac{6\sin(90)}{\sqrt{85}}=\dfrac{6}{\sqrt{85}}
