Answer:
-16
Step-by-step explanation:
multiply 4x4 and then determine if its negative or positive
Answer:
the answer is 45 over 6
Step-by-step explanation:
A shortcut is "2 x _____ is 6", which is 3.
Multiply 15 by 3 also, to get 45,
45/6
![\sqrt[8]{48^4}](https://tex.z-dn.net/?f=%20%5Csqrt%5B8%5D%7B48%5E4%7D%20)
can be rewritten as
to the
power:
Now, applying exponent rules (multiply exponent inside parentheses by the one outside parentheses), we get:
This is equivalent to
, so now, we just simplify:
So:
![\sqrt[8]{48^4} =4 \sqrt{3}](https://tex.z-dn.net/?f=%20%5Csqrt%5B8%5D%7B48%5E4%7D%20%3D4%20%5Csqrt%7B3%7D)
Answer: question 5 is C
Question 4 is 37.68
Question 3 is 153.86 ft sq
The question about finding the area with a diameter of 16mm is 803.84
The next one is A. 25÷8
Step-by-step explanation:
C = 2 pi r
C = 2 pi (7.8) and you get 49.01
Becuse the question is asking to round c is the best choice
When using the formula of C = 2 pi r, since radius is half of the diameter, 12÷2=6
The formula for this one is A = pi r sq
You have the radius for this one is 7
Put 7 into that and you get. ~153.94
