Answer:
Solution given:

Since it is a form of (a+b)²
we have
(a+b)²=a²+2ab+b²
here
a=x
b=b/2a
now
substituting value
x²+2*x*b/2a+(b/2a)²

Answer:
Undefined
Step-by-step explanation:
m=(y2-y1)/(x2-x1)
m=(-3-2)/(17-17)
m=-5/0
m=undefined
To determine the amount of gold plating necessary for the similar box, you will use the fact that it is 8 times larger in volume to determine how many times larger the area is. This would be what you will multiply $125 by.
Volume is a three dimensional measurement, so the fact that it is 8 times larger tells us each dimension was 2 times larger (2 x 2 x 2=8).
Area is a two dimensional measurement, so the area would have been 2 x 2 or 4 times larger. This means the price would be 4 times as much.
$125 x 4 = $500.
It will cost $500 to gold plate the similar jewelry box.
Answer:
Step-by-step explanation:
(-1 -4)/(2 - 3) = -5/-1 = 5
y - 4 = 5(x - 3)
y - 4 = 5x - 15
y = 5x - 11
12 + 3x = 30 // what is x?
3x = 18
x = 6
