The sum of a and b will be the coefficient of the x term of the trinomial. This can be seen below.
(x + a)(x + b)
= x² + bx + ax + ab
= x² + (a+b)x + ab
x is being multiplied by both a and b individually and the products are being added, so sum of a and b appears as the coefficient of x term.
Thus the answer to this question is option C
Answer:
3√15
Step-by-step explanation:
x=y
x^2+x^2 = 9*30
2x^2 = 270
x^2 = 9*15
x = y = 3√15
Answer:
1.x^2
2.x+8
3.x
4. 8x
Step-by-step explanation:
Length of old is x inches.
Because it is square we have that area of the old canvas : 
When we read : width of new is increased by 8 so : x+8
Length is x.
The difference of areas:
Old canvas : A1=
New canvas : 
Now we can find A2-A1:

Answer:
The answer is
<h2>

</h2>
Step-by-step explanation:
To find an equation of a line in point slope form when given the slope and a point we use the formula

where
m is the slope
( x1 , y1) is the point
From the question the point is (-5,-2) and the slope is - 6/5
The equation of the line is

We have the final answer as
