Answer:
the answer for this problem is x^2+2x-15
Step-by-step explanation:
(x+5)(x-3)
x(x-3)+5(x-3)
x^2-3x+5(x-3)
x^2-3x+5x-15
=x^2+2x-15
The sum of the opposite angle of the Isosceles trapezoid is supplementary. The value of x from the given diagram is 10

Isosceles trapezoid</h3>
The sum of the opposite angle of the Isosceles trapezoid is supplementary. According to the theorem;
14x + 3x + 10 = 180
17x = 180 - 10
17x = 170
Divide both sides by 17
17x/17 = 170/17
x = 10
Hence the value of x from the given diagram is 10

Answer:
Step-by-step explanation:
To complete the square you need to add 
to both sides. (Parenthesis around b/2)
b = 10
b/2 = 5
(b/2)^2 = 25
+10x + 16 = 0
subtract 16 to both sides
+ 10x = -16
add 25 to both sides
+10x + 25 = 9

Step-by-step explanation:
Answer:
See below.
Step-by-step explanation:
The set of all real numbers except for 100 in set builder notation (assuming the variable is x) is:
The very first x represents the variable.
The second with the R represents the number. Here, we want all real numbers.
And the third is the constraint. We want all real numbers except for 100.
