Answer: h = 30.5
Step-by-step explanation
2h - 49 = 12
+49 +49
Add 49 to both sides. Inverse operation
2h = 61
2h/2 = 61/2
Divide 2 to both sides to get answer. Inverse operation
h = 30.5
Check:
2(30.5) - 49 = 12
61 - 49 = 12
12 = 12
90,180 is the same as R so it is
Answer:
x^2 + 14x + 49
Step-by-step explanation:
Use the distributive property:
(x + 7)(x + 7) = x^2 + 7x + 7x + 49 = x^2 + 14x + 49
Answer:

Step-by-step explanation:
Your calculator can do this for you.
Or, you can simplify to

Answer is number 2
F(3)= (3-1)^2+ 3(3)=4+9= 13 so the first option is wrong
F(-2)= (-2-1)^2+ 3(-2)= 9-6=3 third options is wrong
F(-15)= (-15-1)^2 +3(-15)= 256-45= 211 fourth option is wrong
