Answer:
x=y
Step-by-step explanation:
Answer: The equation for the line of reflection will be x = y.
Next time, please list the possible answer choices. Without them, all I can do is to attempt this problem without having those choices as guidelines.
I must assume that your expression x^4-5x+3/x^2+7 actually meant:
5x + 3
x^4 - ---------------
x^2 + 7
and I assume that this result was one of the several possible answer choices.
Answer:
306 mi^2
Step-by-step explanation:
surface area = area of base + lateral area
surface area = s^2 + 4bh/2
surface area = (10 mi)^2 + 4(10 mi)(10.3 mi)/2
surface area = 306 mi^2
Part A: 9 and 7+2x
Part B: 1 term
Part C: 2 from 2x
Exterior angle = the sum of the two included interior angle
125+21= 146
