Hope this helped :)
One of the rules of logarithms is as follows;

We can now insert the corresponding values in the question provided, as shown below;

Note that, one of the rules of exponents, states that a number when raised to the power of a negative value, is equivalent to the reciprocal of that expression. An example is shown below;

Therefore, our equation can now be re-written as follows;

However, the question requires the answer to be expressed in exponential form. Therefore,
10 x 15=150
150 is the answer
Volume of square pyramid = a^2 x h/3
Volume of pyramid A = 9^2 x 10/3
Volume of pyramid A = 270 cubic inches.
Divide volume of B by A:
1350/270 = 5
5 x 100 = 500 % bigger
To check, rewrite 500% as a decimal and multiply by the volume of A:
500%/100 =5
270 x 5 = 1350
This equals the volume of B, so the scale was calculated correctly.
Answer:
x= -74 or -84
Step-by-step explanation:
x^2+3x+37=-7x
x^2+3x+7x+37=0
x^2+10x+37=0
this convert to following

-b= -(10), a= 1, c =37
according to that
x= -74 or x= -84
