Answer:
See explanation, and ask for more details if unclear!
Step-by-step explanation:
The perfect square of this equation is
, since the square would be
. 1/4=4/16, meaning that you can set up the equation in the following way:


Take the square root of both sides:

Add 1/2 to both sides:
. Hope this helps!
Answer:
The measure of the missing angle is 90°
Step-by-step explanation:
∵ This figure is a quadrilateral
∴ the sum of measures of its angles = 360°
∴ m∠x = 360 - 107 - 72 - 91 = 90°
#3: 15
#4: 13.2
#5: 5.44 (curious as to how you guessed 7)
#6: 7
#7: 7.3
#8: 15
#9: You'd round 0.9 to 1 and 3.78 to 4. 4/1 = 4
#10: Round 2.5 to 3. 36/3 = 12
#11: If they want you to round 0.25 down to 0, then 7/0 is undefined.
#12: 9.5 rounds to 10 142.5 rounds to 143. 143/10 = 14.3
#14: 24.8 cm divided by 175 = approximately 0.1417 cm per year. Round that up to approximately 0.14 per year.
Answer:
B) linear function with a positive rate of change
Step-by-step explanation:
Each increase by 1 m^2 in area produces the same 0.2 kW increase in power, so the relationship between area and power is linear. Since they both go up (or both go down), the "rate of change" is positive. (If it were negative, one would go down when the other went up.)
The best description is that of B.
