Answer: 2√3
Step-by-step explanation: To divide √60 by √5, we simply divide the numbers that are inside the radicals.
Since the quotient of 60 divided by 5 is 12,
the square root of 60 divided by the square root of 5 is √12.
However, we can simplify the square root of 12.
The √12 breaks down into 4 · 3 and 4 breaks down into 2 · 2.
The 2's match up, so a 2 comes outside of the radical.
Since the 3 doesn't pair up, it stays inside.
So our answer is 2√3.
Answer:
-4
Step-by-step explanation:
-2+3(-4)-5(-2)
PEMDAS says multiply and divide first
-2 -12 +10
Add and subtract from left to right
-14+10
-4
Answer: the length of the shortest side is 15ft.
the length of the shorter or third side is 18ft
the length of the longest side is 26ft
Step-by-step explanation:
Let x represent the length of the shortest side of the triangular section.
Let y represent the length of the third or shorter side of the triangular section.
Let z represent the length of the longest side of the triangular section.
The perimeter of the triangular section is 59 ft. It means that
x + y + z = 59 - - - - - - - - - -1
the longest side of a triangular section is 4 ft shorter than twice the shorter side. It means that
z = 2x - 4
the third side is 3 feet longer than the shortest side. It means that
y = x + 3
Substituting z = 2x - 4 and y = x + 3 into equation 1, it becomes
x + x + 3 + 2x - 4 = 59
4x - 1 = 59
4x = 59 + 1 = 60
x = 60/4 = 15ft
y = x + 3 = 15 + 3
y = 18 ft
z = 2x - 4 = 2 × 15 - 4
z = 26
Answer:
-6.4
Step-by-step explanation:
23.8,12.1 = 17.95
17.6,31.1 = 24.35
17.95-24.35
-6.4
Answer:
see below
Step-by-step explanation:
He forgot to multiply 'x' by '2' in the first step
It should be
4x-1 = 5 + <u>2</u> x
2x = 6
x = 3
