Answer:
x=5 twice
Step-by-step explanation:
x^2-10x+25=0
multiply the coefficient of x^2 and the last term
1X25=25
find two numbers you can multiply to get 25 and add to get -10
-5 + (-5)=-10 the middle term
replace -10x with -5x -5x and solve the equation
x^2-5x-5x+25=0
factorise by grouping
x(x-5)-5(x-5)=0
(x-5)(x-5)=0
Either x-5=0,x=5 or x-5=0,x=5
Therefore x=5 twice.
Answer:
x - 3y + 8
Step-by-step explanation:
The perimeter of a triangle is sum of all the three sides.
One side is 5x + y
Another side is 7 + x
Let third side be m
And perimeter is 7x - 2y + 15
We simply sum the 3 sides and equate it to expression of perimeter and find m(third side). Shown below:
5x + y + 7 + x + m = 7x - 2y + 15
6x + y + 7 + m = 7x - 2y + 15
m = 7x - 2y + 15 - 6x - y - 7
m = x - 3y + 8
This is the length of the third side "x - 3y + 8"
Answer:
5-m is the expression is equivalent to - m + 5.
