Area of a triangle = 1/2 x base x height.
Replace are and base to get:
82.5 = 1/2 x 15 x height
Multiply both sides by 2:
165 = 15 x height
Divide both sides by 15:
Height = 165 / 15
Height = 11 inches.

Answer:
x^2 -5x +14 = 10^(2x +4)
Step-by-step explanation:
The relationship is ...
log(a) = b ⇔ a = 10^b
__
Using this with a=x^2-5x+14 and b=2x+4, we have ...
x^2 -5x +14 = 10^(2x +4)
_____
<em>Additional comments</em>
In plain text, the exponent needs parentheses, because superscript formatting is not available to tell what is and isn't part of the exponent.
The base of "log" is assumed to be 10 in high school algebra. In the larger world, "log" is often used in place of "ln" to mean the logarithm to base 'e'.

The one solution is approximately x = −1.32505947996.
1 minute = 60 seconds
3 minutes= 180 seconds
multiply 200 x 180= 36,000 beats
hope this helps
It’s 45, as the equation for a parallelogram is A= bxh, and 9x5 is 45
