Answer:
x^2 + 18x + 76 + 5 = 0 + 5
Step-by-step explanation:
The first step is to determine the constant that is needed to be able to write the expression in the desired form. That constant is the square of half the x-term coefficient: (18/2)^2 = 9^2 = 81.
The constant that is present is 76, which is 5 fewer than the needed constant, so the "first step" is to add 5 to both sides of the equation:
x^2 + 18x + 76 + 5 = 0 + 5
Then the next step would be to write the left side as a square:
(x +9)^2 = 5 . . . . . . . p = -9; q= 5
Answer:

Step-by-step explanation:
Base is an equilateral triangle
slant hight= 12 in
side of base= 5 in
so, perimeter of base = 3(5)=15 in
lateral area = 1/2 pl =1/2 (15)(12) in
=90 in²

Answer:
Slope: 
Equation: 
Step-by-step explanation:
The line of the best fit passes through the points (0,8) and (4,6).
If the line passes through the points
and
then the slope of the line is

Hence, the slope of the line of the best fit is

The equation of the line is

where m is the slope and b is y-intercept, so the equation of the line of the best fit is

Answer:
y = 18 + 0.50x
Step-by-step explanation:
I think that is the answer.
