What is the answer for this Evaluate 3|-3|.

zhenek [66]

Answer: 9

Concept:

Here, we need to know the idea of absolute value.

The absolute value of a number or integer is the actual distance of the integer from zero, in a number line.

There are no negatives in absolute value. So in practice "absolute value" means to remove any negative sign in front of a number, and to think of all numbers as positive.

Solve:

Given

3 |-3|

Expand absolute value sign, which means making [-3] positive

= 3 × (3)

Simplify by multiplication

= $\boxed{9}$

Hope this helps!! :)

$\dfrac{3}{2 + \sqrt{2} }$

To rationalise the denominator, this is a standard step:

Answer: Option A

---------------------------------------------------------------------------------------------------

Let me continue to complete the question, though it is not ask for

$= \dfrac{3(2 - \sqrt{2})}{(2 + \sqrt{2)}(2 - \sqrt{2}) }$

$= \dfrac{3(2 - \sqrt{2})}{4 - 2 }$

$= \dfrac{6 - 2\sqrt{2}}{2 }$

svetoff [14.1K]

Answer:

if angles shown are right angle then from corner to midpoint line if this is symettrical angles are 45 and 45. if area is asked of you need to

Step-by-step explanation:

To find the area of any right triangle, you simply multiply the lengths of the two sides that are perpendicular to each other, and then take half of that. if you could flip one of them and move it on top of the other, they would match exactly. The rectangle has an area of 2 × 4 = 8 square units.
