Just substitute 4 for x in the given equation:
h(4) = 3^4 - 7 = 81 - 7 = 74 (answer)
Answer:
side A 14, side b is11
Step-by-step explanation:
The answer is X = 5 because first you have to take away 2x from that side so u minus 2x from 4x that gives u: 72 + 2x = 82 then you have to minus 72 from both sides and that gives you 2x = 10 once you have that you divide both sides by 2 because you want the X by itself and once you get that X = 5. Hope this helped!
Answer: 45
Step-by-step explanation:
Answer:
x=35, y=21. (35, 21).
Step-by-step explanation:
x+y=56
x-y=14
------------
2x=70
x=70/2
x=35
35+y=56
y=56-35
y=21
