(f+g)(x) = 6x^2+2x-7+4x-3=6x^2+6x-10
(f-g)(x)=6x^2+2x-7-4x+3 = 6x^2-2x-4
(2)
(f+g)(x)=2x-3x+1-2x=-3x+1
(f-g)(x)=2x-3x-1+2x=x-1
Y + 6 = 4/5( x + 3)
y + 6 = 4/5x + (3(4))/5
y + 6 = 4/5x + (12)/5
y + 6 = 4/5x + 12/5
y + 6 (-6) = 4/5x + 12/5 (-6)
y = 4/5x + 12/5 (- 30/5)
y = 4/5x - 3.6 ( y = mx + b formula)
4/5 = 0.8
y = 0.8x - 3.6
x = 1
y = 0.8(1) - 3.6
y = - 2.8
x = 2
y = 0.8(2) - 3.6
y = 1.6 - 3.6
y = -2
x = 3
y = 0.8(3) - 3.6
y = 2.4 - 3.6
y = - 1.2
x = 4
y = 0.8(4) - 3.6
y = 3.2 - 3.6
y = - 0.4
x = 5
y = 0.8(5) - 3.6
y = 4 - 3.6
y = 0.4
etc.

all you have to do it convert the it to the mph
Answer:
75cm^2
Step-by-step explanation:
When you say a rectangular prism, it means it has the base has 4 sides of which opposite sides are equal as a rectangle. This sides substends so we have a total of 6 surfaces in this prism.
This 6 surfaces has 3 surface area the same.
The surface area = sum of area of all faces.
325= 50 + 50 + 37.5 + 37.5 + 2x; where X is the area of the surface unknown.
325= 100+ 75 + 2x
325-175= 150
150= 2x
X= 150/ 2 = 75 cm^2
