You already have the answer. It is "One type of proof is a two-column proof. It contains statements and reasons in columns. Another type is a paragraph proof, in which statements and reasons are written in words. A third type is a flowchart proof, which uses a diagram to show the steps of a proof." which looks correct to me.

–6 < 2x – 4 < 4 solve the inequality

Ira Lisetskai [31]

Answer:

The answer is

<h2> $- 1 < x < 4$ </h2>

Step-by-step explanation:

<h3> $- 6 < 2x - 4 < 4$ </h3>

First of all add 4 to both sides of the inequality to make 2x stand alone

That's

<h3> $- 6 + 4 < 2x - 4 + 4 < 4 + 4 \\ - 2 < 2x < 8$ </h3>

Divide both sides of the inequality by 2 inorder to find x

That's

<h3> $\frac{ - 2}{2} < \frac{2x}{2} < \frac{8}{2}$ </h3>

We have the final answer as

<h3> $- 1 < x < 4$ </h3>

Hope this helps you

A square has a perimeter of 12x + 52 units. Which expression represents the side length of the square in units?

Gnesinka [82]

Answer:

C

Step-by-step explanation:

If a square has 4 sides and the perimeter is 12x + 52, you have to divide 12x + 52 by 4 to get the length of a single side

12x / 4 = 3x

52 / 4 = 13

3x + 13

A=1/2h (b+c) solve for b

Illusion [34]

A=1/2h(b+c)
times both sides by 2/1
2A=h(b+c)
divide both sides by h
$\frac{2A}{h}$ =b+c
minus c from both sides
$\frac{2A}{h}$ -c=b

Can someone help me!

Answer:

m∠A = 48.81°

Step-by-step explanation:

Given triangle is a right triangle and we have to measure ∠A.

Since, opposite side and adjacent sides of angle A has been given

So we will apply tangent rule to get the measure of angle A.

tan(∠A) = $\frac{\text{Opposite side}}{\text{Adjacent side}}$

tan(∠A) = $\frac{8}{7}$

∠A = $\text{tan}^{-1}(\frac{8}{7})$

∠A = 48.814

≈ 48.81°

-3(3+x)+4(x-6)=-4 Please help me with this question

dsp73

Answer:

$\boxed{ \bold{ \huge{ \sf{x = 29}}}}$

Step-by-step explanation:

$\sf{ - 3(3 + x) + 4(x - 6) = - 4 }$

Distribute -3 through the parentheses

Similarly, Distribute 4 through the parentheses

⇒ $\sf{ - 9 - 3x + 4x - 24 = - 4}$

Collect like terms

⇒ $\sf{x - 9 - 24 = - 4}$

Calculate

⇒ $\sf{x - 33 = - 4}$

Move 33 to right hand side and change it's sign

⇒ $\sf{x = - 4 + 33}$

Calculate

⇒ $\sf{x = 29}$

Hope I helped!

Best regards!!
