Answer:

4(x+4)

Step-by-step explanation:

multiply the numbers

3(x+3)×2 - 2(x+3) +4

collect like terms

6(x+3) - 2(x+3) +4

Factor the expression

4(x+3)+4

Add the numbers

4x + 12 +4

4x + 16

4(x+4)

The area of triangle ABC is 24 square centimeters. If B = 30° and a = 6 cm, what is the measure of side c? 4 cm 8 cm 16 cm 32 cm

disa [49]

Answer:

16 cm

Step-by-step explanation:

Given : The area of triangle ABC is 24 square centimeters.

To Find: If B = 30° and a = 6 cm, what is the measure of side c?

Solution:

Formula : $Area = \frac{1}{2} \times a \times c \times sin B$

a = 6

Area = 24

B = 30°

Substitute the values in the formula

$24 = \frac{1}{2} \times 6 \times c \times sin 30$

$24 = \frac{1}{2} \times 6 \times c \times \frac{1}{2}$

$24 =3 \times c \times \frac{1}{2}$

$\frac{24 \times 2}{3} =c$

$16=c$

Hence the measure of side c is 16 cm

So, Option c is correct.

Scenario:

Anettt [7]

To find the area you multiply the length by the width.

W = the width, and you are told the length is 5 meters longer, so the length would be (W +5)

Now multiply those together to equal 20,000 square meters:

w(w+5) = 20,000
