Area of rectangle = Length x width, Area of triangle - (1/2) base x height
Surface Area is the sum of the area of all of the faces.
Your picture has 5 faces:
1) rectangle on the left
2) square in the middle
3) rectangle on the right
4 & 5) 2 congruent (identical) right triangles
Area of face #1: 5 x 4 = 20
Area of face #2: 4 x 4 = 16
Area of face #3: 3 x 4 = 12
Area of face #4: (1/2) x 3 x 4 = 6
Area of face #5: (1/2) x 3 x 4 = 6
Sum of the Area of the faces: 60
Answer: Surface Area of the figure is 60 units²
Volume = Length x width x height
= 5 x 4 x 3
= 60 units³
Answer: Volume of the figure is 60 units³

Answer:
all real numbers except ±5.
Step-by-step explanation:
Each function (f(x), g(x)) has a domain that is all real numbers. Their quotient (f(x)/g(x)) must exclude values that make g(x) = 0. The quotient is undefined when the denominator is zero. Those excluded values are x = ±5.
The domain of (f/g)(x) is all real numbers except ±5.

Of course you recognize x^2 -25 = 0 has solutions x = ±√25 = ±5. You can get there two ways:
- add 25 and take the square root: x^2=25; x=±√25.
- factor the difference of squares and set the factors to zero: (x-5)(x+5)=0 has solutions x-5=0 and x+5=0, that is, x = ±5.
5/8 = 3/4+1/16 is false because, the final values compared on each side of equation is not the same
- 5/8 = 0.625
- 3/4+1/16 = 0.8125
0.625 = 0.8125, it is not equal but less than
