Try to rewrite the equation;
You know that 5 can be written as log3(3^5)
log3(3^5)=log3(x^2+18) <-- you can now cancel out log3
3^5=x^2+18
243-18=x^2
225=x^2
√225=x
+-15=x
You see that even if x is negative, the squared will always give a positive answer. Therefore, +15 and -15 are both possible answers.
Hope I helped :)
C. The lines curve opposite when typed into a graphing calculator. Check Desmos in the future when you need to see how line map out on to a graph. Hope this helps.
Hey there!
36(2) * 30
36(2) = 72
72 * 30 = 2,160
3^3 = 3 * 3 * 3 = 9 * 3 ➡️ 27 ❌
3^4 = 3 * 3 * 3 * 3 = 9 * 9 ➡️ 81 ❌
3^8 = 6,561 ❌
3^12 = 531,441 (maybe)
Answer: Option D. 3^12 ☑️
Good luck on your assignment and enjoy your day!

The missing coordinates of the parallelogram is (m + h, n).
Solution:
Given shape is a parallelogram.
Construction: Draw a line joining the diagonals.
<em>In parallelogram, diagonals bisect each other.</em>
Solve it using mid-point formula:
Here
Using this midpoint find the missing coordinate.
Let the missing coordinates by x and y.
Here
Now equate the x-coordinates and y-coordinates.
Multiply by 2 on both sides of the equation, we get
m + h = x, n = y
x = m + h and y = n
Hence the missing coordinates of the parallelogram is (m + h, n).
1/4 of 28 is 7 so, therefore, you ate 7 smarties.
28 - 7 = 21
There are 21 smarties left.
Hope this helps! :)
