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 :)
Correct!
Your notes on the right side are correct, too.
<em>In</em>dependent -- <em>not </em>dependent on another variable
Dependent -- dependent on another variable
The height of the plant varies because/due to of the quality/quantity of fertilizer.
So, the height is changed by the fertilizer.
Thus: height is dependent and fertilizer amount is independent.
Given:
A figure.
To find:
The angle number which is supplementary to ∠OKL.
Solution:
The angles which lie on the same side of a straight line and their sum is 180 degrees, then they are called supplementary angles.
From the given figure it is clear that ∠OKL is lies on the intersection point K of lines OJ and GL.
Angle 11 and angle 12 lie on the same side of the straight line GL.
So, angle 11 and angle 12 are supplementary angles.
Therefore, angle 11 is supplementary to ∠OKL.
Answer:
546
Step-by-step explanation:
3 1/2 times 3 equals 10 1/2. 10 1/2 times 52 equals 546.
