Answer: 10u3 + 4u2 - 2u + 10

Step-by-step explanation:

( 4u3 + 4u2 + 2) + ( 6u3 - 2u + 8)

opening the bracket

4u3 + 4u2 + 2 + 6u3 - 2u + 8

collecting like terms

4u3 + 6u3 + 4u2 - 2u + 2 + 8

10u3 + 4u2 - 2u + 10

In ΔBCD, the measure of ∠D=90°, the measure of ∠C=83°, and DB= 1.3feet. What is the length of CD to the nearest tenth of a foot.

Lina20 [59]

Answer:

$CD\approx0.2$

Step-by-step explanation:

By the tangent ratio, $tanC=\frac{DB}{CD}$ . Substituting the given values into this equation gives us:

$tan83$ ° $= \frac{1.3}{CD}$

$CD*tan83$ ° $=1.3$ (Multiply both sides of the equation by $CD$ )

$CD=\frac{1.3}{tan83\textdegree}$ (Divide both sides of the equation by $tan83\textdegree$ )

$CD=0.15962\approx0.2$

Hope this helps!
