The formula would be:
8x=35
To find x, you need to divide both sides by 8:
x=35/8=4.375
So the answer is C
Type surface area of a triangular prism on google for a calculator
or height X Base side A X base side B X base side C
the base is the triangular side the height is the long part
9x$30$270
$270 is your answer hope i helped
Answer:
x= 45
Step-by-step explanation:
angle EOB = 90 degrees so angle EOA must also be 90 degrees. Divide 90 by 2 = 45. You can figure out the rest from now on.
Answer: In June 2097
Step-by-step explanation:
According to the model, to find how many years t should take for 
we must solve the equation 
. Substracting 21100 from both sides, this equation is equivalent to 
.
Using the quadratic formula, the solutions are 
and 
. The solution 
can be neglected as the time t is a nonnegative number, therefore 
.
The value of t is approximately 85 and a half years and the initial time of this model is the January 1, 2012. Adding 85 years to the initial time gives the date January 2097, and finally adding the remaining half year (six months) we conclude that the date is June 2097.
