Answer: i’m sorry please mark me a thanks i really need help with a school project and i need points to ask a question i hope you have a good day
4x^2 - 30 = 34
4x^2 = 34 + 30
4x^2 = 64
x^2 = 64/4
x^2 = 16
x = sqrt 16
x = -4 and 4......E and F
Essentially, we just use the pythagorean theorem to solve:
7^2 + 3^2 = c^2
49 + 9 = c^2
58 = c^2
c = sqrt 58
The answer is Option D.
I got -9a2b I hope this helps !!!
3x-2 = x + 5
sum means +
2 less means -2
product of 3 and x means 3x
