Answer:

x = 8

Step-by-step explanation:

Complimentary angles are angles that add up to 90 degrees. If ABC and DBC are complimentary, then when added together, it equals 90 degrees.

ABC + DBC = 90

6x+13+4x−3 = 90

10x+10 = 90

10x = 80

x = 8

An angle measures 14° more than the measure of its supplementary angle. What is the measure of each angle?

luda_lava [24]

Answer:83 and 97

Step-by-step explanation:

Let the angle be y

The second angle will be y+14

A supplementary angle equals 180°

y + y + 14=180

2y+14=180

2y=180-14

2y=166

y=166/2

y=83

The first angle is 83.

Second angle will be 83+14=97.

Choose the correct simplification of the expression −3x2(5x − 4x2 − 6).

Bess [88]

Answer B.
$- 3 {x}^{2} (5x - 4 {x}^{2} - 6) \\ = - 15 {x}^{3} + 12 {x}^{4} + 18 {x}^{2} \\ = 12 {x}^{4} - 15 {x}^{3} + 18 {x}^{2}$
