Its OP I am working on this right now and got a hundred on a topic test i would know
For this case we define the following variable:
- <em>x: number of stamps
</em>
We now write the equation that models the problem:
From here, we clear the value of x.
We have then:
Answer:
The number of stamps he has is:
Answer:
(x + 2)² = 7
Step-by-step explanation:
We have to complete the square in the given equation
3x² + 12x = 9
3x² + 12x - 9 = 0
3[x² + 4x -3] = 0
3[x² + 2(2x) + 4 - 4 - 3] = 0
3[x² + 2(2x) + 4] - 3 × 7 = 0
3[x² + 2]² - 21 = 0
(x + 2)² = = 7
Therefore, the square form of the equation is (x + 2)² = 7
Hope this helps (:
Answer:
1.
circumference=diameter ×pi
=(29×2)× pi
=59×pi
area= pie × radius²
=pi×29²
=841pi
2.
circumference =pi×16.5
area=pi×8.25²
3.
153.94÷pi
radius=square root of 49.00062388
=7.000044563
times by 2
=14.00008913
4.
28.27÷pi
8.998620482=diameter
divide by two to find radius
4.499310241
then square
20.24379265
then times that by pi
=63.59775026
