Answer:

6 and -6 are solutions because any negative multiplied by a negative is a positive. The negatives cancel each other out but this only works for multiplication from what I know.

Step-by-step explanation:

6 x 6 = 36

-6 x -6 = 36

In the accompanying diagram, line BD bisects acute angle ABC and line AD is parallel to line BC. What kind of triangle must tria

galina1969 [7]

Answer:

isosceles

Step-by-step explanation:

With AD║BC, ∠ADB ≅∠DBC. The angle bisection also ensures that ∠ABD≅∠DBC. Hence the two angles ABD and ADB must be congruent to each other.

A triangle with two congruent internal angles is an isosceles triangle.

What is the distance from Cto D?

IRINA_888 [86]

Given:

The two points C(2,-1) and D(5,3) on a coordinate plane.

To find:

The distance from C to D.

Solution:

The distance between two points is defined by the distance formula.

$d=\sqrt{(x_2-x_1)^2+(y_2-y_1)^2}$

The two points are C(2,-1) and D(5,3). Using the distance formula, we get

$CD=\sqrt{(5-2)^2+(3-(-1))^2}$

$CD=\sqrt{(3)^2+(3+1)^2}$

$CD=\sqrt{(3)^2+4^2}$

On further simplification, we get

$CD=\sqrt{9+16}$

$CD=\sqrt{25}$

$CD=5$

The distance from point C to D is 5 units. Therefore, the correct option is A.

Help please! It would really be nice and I will reward a brainliest to the right and best answer!

Nikolay [14]

Well is the length is 4 ft, and 1 ft is 12 inches we need to do 12×4, which is 48.

So now we know that the length is 48, and the height is 4, so it would be 48×4, which gives us our answer, 192 inches!
