Answer:

Step-by-step explanation:

If you want to make

x^2-12x

into a perfect square binomial, take half the linear term, square it, then add it to both sides.  Our linear term is 12.  Half of 12 is 6, and 6 squared is 36.

The value that makes this a perfect square binomial is 36.

Writing the expression as a square of the binomial is:

(x^2-12x+36)-->(x-6)^2

The sum of 2 numbers is 25. Their difference is 7. Find the numbers. Let x=1st number and y=2nd number
Alex Ar [27]

Answer:

x= 16 and y = 9

Step-by-step explanation:

1 st equation ; x+y = 25

2 nd equation ; x- y = 7

from 1 st equation

x = 25 - y

now putting value of x in 2 nd equation

x- y = 7

25 - y-y = 7

25 -2y =7

25-7 = 2y

18 = 2y

18/2 = y

y = 9

again

putting value of y in 1 st equation

x = 25-y

x = 25-9

x= 16

Examine the system of equations.
MakcuM [25]

Answer:

\boxed{\boxed{\sf x=-3}}

Step-by-step explanation:

\sf y = -3x - 2

\sf y=7

We'll substitute y into the equation:

\sf 7 = -3x - 2

Switch sides:

\sf -3x-2=7

Add 2 to both sides

\sf -3x-2+2=7+2

\sf -3x=9

Divide both sides by -3:

\sf \cfrac{-3x}{-3}=\cfrac{9}{-3}

\sf x=-3

Therefore, the value of x/solution is -3
