1.7,5-1,5=6
2.10-11=-1
3.6×-1=-6
4.-6+2=-4
Answer:
Step-by-step explanation:
f(x) = (3x4 - 12)3 and h(x) = x3.
g(x) = 3x4 - 12
since f(x) = (hºg)(x) = h(g(x))
Answer: V=πr2h

Step-by-step explanation:
It's 39/100 because we can't divide both numbers with a whole number
The answer is option C) 19,-19
<u>Step-by-step explanation</u>:
Given, z² = 361
To eliminate the square of z, take square root on both sides
z = √361
- The factor of 361 could not be an even number, since the last digit of 361 is odd. So, eliminate option A)
- The option B) is a larger number and it cannot be the answer. So, eliminate it.
- Try option C) works or not. (19)² = 19
19 = 361 and (-19)² = -19
-19 = 361. - Therefore, z = √361 = ±19. option C) is the correct answer.
