Answer:
the answer is A. 4ft
Step-by-step explanation:
12 feet in the 4 yards 12 divided by 3 equal 4
25% is the same as 1 / 4 you divide 60 by 4
So the first one is (7x)^(1/2) or square root of 7x minus - 5 square root all squared so
([7x^(1/2)]-[5^(1/2)]) times ([7x^(1/2)]-[5^(1/2)])
or 7x-(35x^(1/2))-5+(35x^(1/2)) or 7x-5
number 2
since 11 is 1/2 of 22 it can be written as
the square root of 3 or 3^(1/2)
Answer:
z - x.
Step-by-step explanation:
| 0 0 x-z |
| 0 1 y+z | = 0 |1 y+z| + 0 | 0 y+z| + x-z | 0 1 |
| 1 z z^2 | ||1 z^2| | 1 z^2 | | 1 z |
= 0 + 0 + (x - z)(0*z - 1*1)
= -(x - z)
= z - x
