8 0

Answer:

False

Step-by-step explanation:

2 = x - 8

Add 8 to each side

2+8 = x-8+8

10 = x

x=4 is not a solution

For this case we have the following equation:

$2 = x-8$

If we add 8 to both sides of the equation, we have:

$2 + 8 = x-8 + 8\\10 = x$

Thus, the solution of the equation is $x = 10,$ therefore $x = 4$ is not a solution of the given equation.

Answer:

$x = 4$ is not a solution to the given equation.

False

What is the height of a parallelogram with base 6 meters and an area of 90 square meters

bearhunter [10]

Step-by-step explanation:

Given

In a parallelogram

base (b) = 6 meters

Area of parallelogram (A) = 90 m²

height (h) = ?

We know

A = b * h

90 = 6 * h

h = 90 / 6

h = 15 meters.

Hope it will help :)

Use the relationship between the side lengths and the angles opposite those sides. What are the smallest and largest angles of △

DENIUS [597]

Let us take a random triangle we call $\Delta LMN$ for a better understanding of the solution provided here.

A diagram of the $\Delta LMN$ is attached here.

The rule to be applied here is the relationship between the side lengths of a triangle and the angles opposite those sides. This relationship states that:

In a triangle, the shortest side is always opposite the smallest interior angle and the longest side is always opposite the largest interior angle.

Let us verify this using the diagram attached.

As per the diagram, the smallest interior angle is $\angle L$ and the side opposite to it, $MN=24$ has the smallest side just as the relationship had suggested.

Likewise, the largest interior angle is $\angle N=108^0$ and the side opposite to it, LM=45.7 is the longest side just as the relationship had suggested.
