Where is the picture at? I can't see it. Maybe try uploading.
Answer:
D
Step-by-step explanation:
3x * 5x = 15x^2
3x * -3 = -9x
4*5x = 20x
4 *-3 = 12
so 15x^2 +(20x -9x) -12 or 15x^2 +11x -12
Answer:
Given the statement: Square root 300c^9 = 10c^x square root 3 c
⇒
Squaring both sides we get;
Simplify:
We know:
then;
Divide both sides by 300 we get;
On comparing both sides we have;
Subtract 1 from both sides we get;
8 = 2x
Divide both sides by 2 we have;
x = 4
Therefore, for the value of x =4 the given statement is true.
Perpendicular would have a slope of 1/8 and a line paralell to y=-8 would be y=-8+5 because they have the same slope but different y-intercepts.
