Answer:
No. It would be (x + 5)
Step-by-step explanation:
set each of the factors as equal to 0. So if you do x+5=0 then solve for x by subtracting 5 from both sides you get x = -5
The clue is to switch the sign from the factor to get the value of the variable and vice-versa.
Answer:
Step-by-sThe standard form is Ax + By = C
with A being both positive and non-fraction
so we are given 3x - 9 = 7y
we add the 9 to both sides
3x = 7y + 9
and subtract the 7y from both sides
3x - 7y = 9
tep explanation:
Answer: FALSE
Step-by-step explanation:
The first step is to rewrite the equation in the form , then:
Now, we need to calculate the Discriminant with this formula:
We can identify in the given equation that:
Then, we only need to substitute these values into the formula:
Since then the equation has no real solutions.
This is the concept of Pythagorean theorem which states that:
a^2+b^2=c^2
but from the question;
a=x^2+y^2
b=2xy
c=x^2+y^2
therefore substituting the values of a.b and c in our formula we get,
(x^2+y^2)^2+(2xy)^2=(x^2+y^2)^2
x^4-2x^2y^2+y^4+4x^2y^2=x^4+2x^2y^2+y^4
Checking on the difference for squares we consider 1,4,9,16,36,49,64,81,...
given that one of the legs is 11, to get the other leg we look for the square difference of two minimum numbers that will give us 11^2=121
we have;
11^2+60^2=61^2
therefore the answer is:
a=11,b=60 and c=61
