Nah, it's not a right triangle because, the longest side can't insitude its self
Answer:
y = (8/5)x + 15
Step-by-step explanation:
<em>First change the equation to standard form (y=mx+b)</em>
5x + 8y = 16
8y = 16 - 5x
y = - (5/8)x + (16/8)
y = - (5/8)x + 2
<em>Perpendicular Lines have the inverse opposite sign of slope</em>
<em>[For example: inverse opposite sign of 2 is - (1/2)]</em>
Original equation slope (m) : - (5/8)
2nd Equation (m) : 8/5
<em>After finding the slope, plug in the slope and points the standard form equation (y=mx+b)</em>
Point: (-5,7) x : -5 y : 7
Slope (m) : 8/5
y = m x + b
7 = (8/5) (-5) + b
<em>'b' is the y-intercept and the last thing to solve for the equation</em>
7 = - 8 + b
15 = b
<em>Now, put the slope (m) and y-intercept (b) back into the equation</em>
y = (8/5)x + 15
You have less money if you subtract 14.99 - 140 ounces you get -125.01 and if you subtract the other one the other more less than the previous one 100 ounces is better.

The answer is C.
There are 6 faces in this prism. Each pair of opposite faces is two congruent faces.
The front and back faces have dimensions x by x + 4.
The right and left faces have dimensions x + 2 by x + 4.
The top and bottom faces have dimensions x by x + 2.
Let's find the area of each different face.
Front & back:
A = LW = x(x + 4) = x^2 + 4x
Right and left:
A = LW = (x + 2)(x + 4) = x^2 + 4x + 2x + 8 = x^2 + 6x + 8
Top & bottom:
A = LW = x(x + 2) = x^2 + 2x
Now we add the three areas:
x^2 + 4x + x^2 + 6x + 8 + x^2 + 2x =
=3x^2 + 12x + 8
The polynomial above is the sum of the areas of three different faces.
Each of the three different faces has a congruent opposite face with the same area, so we double this area to find the total surface area of all 6 faces.
2(3x^2 + 12x + 8) = 6x^2 + 24x + 16
The answer is option A.
