Step-by-step explanation:
Answer:
U = x + 3 and V = 7
Step-by-step explanation:
Let U = x + 3 and V = 7, then:
=> (x + 3)^2 + 14(x + 3) + 49
= (x + 3)^2 + 2*7*(x + 3) + 7^2
= U^2 + 2UV + V^2
= (U + V)^2
(correct)
To find the slope and y-intercept, you need to get the equation into slope-intercept form, which is y = mx + b, where m is the slope and b is the y-intercept.
-12x - 4y = 10
+12x +12x
-4y = 12x + 10
/-4 /-4
y = -3x - 10/4
Answer:
4 maybe
Step-by-step explanation:
Answer:
<u>Add 3 to both sides of the equation</u>
Solution:
The first step is to basically realize that all it's asking you to do is to find a way to make the expression on the left (
) into an expression that is a perfect square. So what number should you add to both sides such that 
can be factored into 
? Well, we can approach it like this:
Since can be turned into 
, and our original form was , we quickly realize that 
. From there, we can easily tell that 
Plug this into our last value 
to get 16. Therefore, if we compare this with our original equation again , we notice that 13 + j = 16.
Thus, j = 3 for the last answer.
Add 3 to both sides of the equation.
Note: With more practice, you will quickly gain enough intuition to notice that 
is very close to 
which can be factored into 
. But for now, the solution above will suffice. I hope this helps :))
