4x + 2 < −2 OR 4x + 2 > 26 <br><br><br> solve pl

inn [45]

Step-by-step explanation:

The easiest thing to do here is:

4x + 2 = -2 and 4x + 2 = 26

Just know whaever you get for x is greater or less than the actual answer.

4x + 2 = -2

- 2 - 2

4x = -4

$\frac{4x}{4} = \frac{-4}{4}$

x = -1 <--- Because -2 is supposed to be greater than x, x equals any number less than -1 but not -1.

4x + 2 = 26

- 2 - 2

4x = 24

$\frac{4x}{4} = \frac{24}{4}$

x = 6 <--- Because 26 is supposed to be less than x, x equals any numbey greater than 6 but not 6

3(x+2)=2(x+5) find the solution

ankoles [38]

Answer:

x=4

Step-by-step explanation:

Step 1: Simplify both sides of the equation.

3(x+2)=2(x+5)

(3)(x)+(3)(2)=(2)(x)+(2)(5)(Distribute)

3x+6=2x+10

Step 2: Subtract 2x from both sides.

3x+6−2x=2x+10−2x

x+6=10

Step 3: Subtract 6 from both sides.

x+6−6=10−6

x=4

Solve for all of the missing angles in the rhombus below, given that m∠3 = 54°. (Round to the nearest tenth as needed.)

Marat540 [252]

The measure of angles 1, 2, 4, and 5 are 54 degrees, 90 degrees, 36 degrees, and angle 36 degrees.

<h3>What is a rhombus?</h3>

A rhombus is a two-dimensional shape having four parallel opposite pairs of straight, equal sides. This shape resembles a diamond and is what you'd find on a deck of cards to represent the diamond suit. Rhombuses can be encountered in a variety of common situations.

We have shown the rhombus in the picture.

As we know the diagonals bisect at a 90-degree angle.

So angle 2 = 90 degree

angle 1 = angle 3

angle 1 = 54 degrees

angle 1 + angle 2 + angle 5 = 180

54 + 90 + angle 5 = 180

angle 5 = 36 degrees

angle 5 = angle 4 = 36 degrees

Thus, the measure of angles 1, 2, 4, and 5 are 54 degrees, 90 degrees, 36 degrees, and angle 36 degrees.
