ivolga24 [154]

Answer:

The correct option is - content analysis

Step-by-step explanation:

Dr. Jones is having his students use: content analysis.

Content analysis is a type of research technique, where we make similar and valid inferences by coding and interpreting information in text forms.

Here Dr. Jones is asking his students to gather information to identify the violent acts in each cartoon show. So, the students will be gathering content or information and then they will come to some inference.

-2(3x+2) is greater than or equal to -6x-4
olchik [2.2K]
The inequality would look like this:

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

To begin to find the solutions, distribute the -2 throughout the set of parenthesis on the left side of the inequality by multiplying the -2 by each term in the set of parenthesis

-2 x 3x = -6x
-2 x 2 = -4

-6x -4 \geq-6x-4

Begin to isolate x by performing the opposite operation of adding -6x on both sides of the inequality

0x -4 \geq-4

Next perform the opposite operation by adding 4 on both sides of the inequality

0x \geq 0

Now, I'm not exactly understanding how that can possibly work. So, I guess I didn't really help you. But add a comment so that we can talk about the problem :)

the area of the garden is:

(7x + 3)(6x - 3)

= 42x² - 21x + 18x - 9

= 42x² - 3x - 9

Find the missing length to the nearest tenth of a meter of the
marin [14]

Answer:

length of the third side may be either 3.4 m or 2.8 m.

Step-by-step explanation:

Measure of two sides of a right triangle are 1.4 m and the other side is 3.1 m.

then we have to find the measure of third side.

If the third side of the triangle is its hypotenuse then

(Third side)² = (1.4)² + (3.1)²

Third side = \sqrt{(1.4)^{2}+(3.1)^{2}}

                 = \sqrt{1.96+9.61}

                 = \sqrt{11.57}

                 = 3.4 m

If the third side is one of the perpendicular sides of the triangle and 3.1 m is hypotenuse, then

(Third side)² + (1.4)² = (3.1)²

(Third side)²= (3.1)² - (1.4)²

Third side = \sqrt{(3.1)^{2}-(1.4)^{2}}

                 = \sqrt{9.61-1.96}

                 = \sqrt{7.65}

                 = 2.76 m

                 ≈ 2.8 m

Therefore, length of the third side may be either 3.4 m or 2.8 m.
