Write the expression in complete factored form<br><br> 4u^2(a-3)+q(a-3)
Sauron [17]

[ Answer ]

\boxed{\bold{4au^{2} \ - \ 12u^{2} \ + \ aq \ - \ 3q}}

[ Explanation ]

  • Factor: 4u^{2}(a - 3) + q(a - 3)

-------------------------------------

  • Expand 4u^2\left(a-3\right): 4au^2-12u^2

4au^2-12u^2+q\left(a-3\right)

  • Expand

q\left(a-3\right): aq-3q

  • Answer

4au^2-12u^2+aq-3q

\boxed{\bold{[] \ Eclipsed \ []}}

Solve for x<br><br>7x/2+5=8<br><br>o x=6/7<br><br>o x=26/7<br><br>o x=21/2<br><br>o x=91/2​
pshichka [43]

Answer:

x = 6/7

Step-by-step explanation:

7x/2+5=8

Subtract 5 from each side

7x/2+5-5=8-5

7x/2 = 3

Multiply each side by 2/7

2/7 * 7/2x = 3*2/7

x = 6/7

Answer:

f(2) = 2.5×2-10.5

=5-10.5

=-5.5

g(2) = 64(0.5×2)

= 64×1

=64

f(3)=2.5×3-10.5

=7.5-10.5

=-3

g(3)=64(0.5×3)

=64×1.5

=96

f(4)=2.5×4-10.5

=10-10.5

=-500

g(4)=64(0.5×4)

=64×2

=128

f(5)=2.5×5-10.5

=12.5-10.5

=2

g(5)=64(0.5×5)

=64×2.5

=150

If
baherus [9]

Answer:  see proof below

<u>Step-by-step explanation:</u>

Given: cos 330 = \frac{\sqrt3}{2}

Use the Double-Angle Identity: cos 2A = 2 cos² A - 1

\text{Scratchwork:}\quad \bigg(\dfrac{\sqrt3 + 2}{2\sqrt2}\bigg)^2 = \dfrac{2\sqrt3 + 4}{8}

Proof LHS → RHS:

LHS                          cos 165

Double-Angle:        cos (2 · 165) = 2 cos² 165 - 1

                             ⇒ cos 330 = 2 cos² 165 - 1

                             ⇒ 2 cos² 165  = cos 330 + 1

Given:                        2 \cos^2 165  = \dfrac{\sqrt3}{2} + 1

                              \rightarrow 2 \cos^2 165  = \dfrac{\sqrt3}{2} + \dfrac{2}{2}

Divide by 2:               \cos^2 165  = \dfrac{\sqrt3+2}{4}

                             \rightarrow \cos^2 165  = \bigg(\dfrac{2}{2}\bigg)\dfrac{\sqrt3+2}{4}

                             \rightarrow \cos^2 165  = \dfrac{2\sqrt3+4}{8}

Square root:             \sqrt{\cos^2 165}  = \sqrt{\dfrac{4+2\sqrt3}{8}}

Scratchwork:            \cos^2 165  = \bigg(\dfrac{\sqrt3+1}{2\sqrt2}\bigg)^2

                             \rightarrow \cos 165  = \pm \dfrac{\sqrt3+1}{2\sqrt2}

             Since cos 165 is in the 2nd Quadrant, the sign is NEGATIVE

                             \rightarrow \cos 165  = - \dfrac{\sqrt3+1}{2\sqrt2}

LHS = RHS \checkmark
