Answer:
The last part.
Step-by-step explanation:
The error is only at the last part. Basically the answer part.
The answer should be —
We don't multiply the square roots when adding or subtracting. That'd contradict the rules.
Here, we let the square root of five as x-term.
As we add up, we would get 13x. Thrn we convert x-term back to square root of five.
The answer would be —
Remember that we don't multiply the square roots when adding or subtracting.
Answer:
a = -5
Step-by-step explanation:
(5 - 3)/(5 - a)
2/(5 - a)
perpendicular of 2/(5 - a) = -(5 - a)/2
(a - 0)/(1 - 0) = -(5 - a)/2
a/1 = -(5 - a)/2
2a = -5 + a
a = -5
Answer:
approximately 42.05
Step-by-step explanation:
We know that the distance formula is 
, so if we use (3,8) as point 2 and (21, -30) as point 1 (note that these are interchangeable), we know that
x₂=3
y₂=8
x₁=21
y₁=-30
Then, we can plug it into the formula to get 
Answer:
x-int: x = -7 and y-int: y = 9
Step-by-step explanation:
9x - 7y = -63
x-int: 9x - 0 = -63
x = -7
y-int: -7y = -63
y = 9
Answer:
p = 9
Step-by-step explanation:
The distributive property can be used to factor the given expression.
__
18n +54 = 18(n +3)
Matching this to the desired form, we see ...
18(n +3) = 2p(n +3)
2p = 18
p = 9 . . . . . . . divide by 2
