Answer:
64 times 4 and add the x at the end = 256x
Step-by-step explanation:
M1= -5 , m2 = 5 inorder to get this you move the constant to the right take the root of both sides separate the solutions and you should get m1= -5, m2 =5
Lets say that the two unknown integers are

and

.
We know the following things about

and

:


And, we want to find

.
To solve this, we'll use the expansion of the squared of the sum of any two inegers; this is expressed as:

So, given what we know about the unknown integers, the previous can be written as:

We can easily solve for

:
The answer is 168.
Another approach to solve the problem is, from the two starting equations, compute the values of

and

, which are 12 and 14, and directly compute their product; however, the approach described is more elegant.
Answer:
x = 5.5 (Fraction 5 and one-half)
Step-by-step explanation:
18 - 7x = -20.5
-18 -18
-7x = -38.5
/-7 /-7
x = 5.5
