Answer:

2x² + x - 3

Step-by-step explanation:

You need to foil the equation.

Foil = (a + b)(c + d) = ac + ad + bc + bd

(x - 1)(2x + 3)

x · 2x = 2x²

x · 3 = 3x

-1 · 2x = -2x

-1 · 3 = -3

Putting them together gets us:

2x² + 3x - 2x - 3

Add like terms to simplify it.

2x² + x - 3

Vertices A and B of triangle ABC are on one bank of a river, and vertex C is on the opposite bank. The distance between A and B
Anna71 [15]

Answer:

The length of side b is 179 ft

Step-by-step explanation:

Given triangle ABC in which  

∠A = 33°, ∠B = 63°, c=200

we have to find the length of b

In ΔABC, by angle sum property of triangle

∠A+∠B+∠C=180°

33°+63°+∠C=180°

∠C=180°-33°-63°=84°

By sine law,

\frac{\sin \angle A}{a}=\frac{\sin \angle B}{b}=\frac{\sin \angle C}{c}

\frac{\sin \angle B}{b}=\frac{\sin \angle C}{c}

\frac{\sin 63^{\circ}}{b}=\frac{\sin 84^{\circ}}{200}

b=200\times \frac{\sin 63^{\circ}}{\sin 84^{\circ}}=179.182887\sim 179 ft

The length of side b is 179 ft

Option C is correct.
