Answer:
-51
Step-by-step explanation:
<u>Step 1: Solve inside the parenthesis</u>
12 + 3(18 - 42) + 9
<em>12 + 3(-24) + 9</em>
<em />
<u>Step 2: Multiply</u>
12 + 3(-24) + 9
<em>12 - 72 + 9</em>
<em />
<u>Step 3: Combine the first two numbers</u>
(12 - 72) + 9
<em>-60 + 9</em>
<em />
<u>Step 4: Combine the last two numbers</u>
-60 + 9
<em>-51</em>

Answer: -51
The area (A) of a regular hexagon in terms of its side length s is
... A = (3√3)/2·s²
For a regular hexagon, its side length is equal to the radius of its circumcircle, given here as 10√3 cm. Putting this value in the formula gives
... A = (3√3)/2·(10√3 cm)² = 450√3 cm²
... A ≈ 779.4 cm² . . . . area of the hexagon
Answer:
Step-by-step explanation:
Given expression:
Convert this into equation and solve for k:
- 33 = k - 15
- k = 33 + 15
- k = 48
So the <u>value of k is 48</u>
141.999 rounded to the nearest
tenth = 142
hundreth =142
ten = 140
hundred = 100
The answer is 7.34.... the form which you have written itself is the standard form.
