Answe
Step-by-step explanation:
To solve the give logarithm we proceed as follows;
log7(3x^3+x)-log7(x)=2
this can be written as:
log7[(3x^3+x)/(x)]=2
but;
log7(49)=2
thus;
log7(3x^3+x)/x=log7(49)
hence canceling log7 we get:
(3x^3+x)/x=49
This can be simplified further to get:
3x^2+1=49
3x^2=49-1
3x^2=48
x^2=48/3
x^2=16
getting the square root of both sides we get:
x=4
the answer is x=4
Answer:
SA = 52 square meters
Step-by-step explanation:
<em>First, the equation I'll be using for this problem is</em><em> SA=2(wl+hl+hw)</em><em>! Our </em><em>width is 4m, </em><em>our </em><em>length is 3m</em><em>, and our </em><em>height is 2m</em><em>. To begin to solve this problem we are going to input these values in to the equation above.</em>
SA = 2(4 × 3 + 2 × 3 + 2 × 4)
<em>Next, we are going to multiply our values inside the parenthesis based on the </em><em>PEMDAS</em><em> </em><em>strategy</em><em> (if you have any questions about this, feel free to ask below :).</em>
SA = 2(12 + 6 + 8)
<em>Now, we can add our values inside the parenthesis.</em>
SA = 2(26)
<em>Finally, all we have to do is distribute the 2 outside of the parenthesis to inside the parenthesis.</em>
SA = 52 square meters

Answer:
i think it's B.2
Step-by-step explanation:
Because it has two sides equal or in this case two sides are the same
