24 days. it has grown 60 cm, because when she got it, it was already 5 cm. So, it grows 2.5 cm each day, so divide 65 cm by 2.5 and you get the answer, 24 days.
11. The sum of these two angles is equal to 180.
So, 3x-4/2+4x+x/2+2=180.
Combine like terms: 4x-4/2+4x+2=180
Find and replace common denominator: 4x-4/2+8x+4/2=180
Combine like terms: 12x/2=180
Simplify: 6x=180, x=30
Check: 90-4/2=43, 120+15+2=137, 43+137=180
<h2>
Hello!</h2>
The answer is:
The difference between the areas of the circles will be:
<h2>
Why?</h2>
To find the diffence in area between the two circles, we need to find both areas and then, subtract the smallest circle area to the largest circle area.
So,
For the small circle, we have:
For the large circle, we have:
Hence, we have that the difference between the areas of the circles will be:
Have a nice day!
<span> 3x^2 − 6x = 24
</span>3x^2 − 6x - 24 = 0
3(x^2 - 2x - 8) = 0
3(x - 4)(x + 2) = 0
x - 4 = 0; x = 4
x + 2 =0; x = -2
answer
<span>C) x = −2, x = 4</span>
