Answer:surface area = 2x^2 + 18x - 34
Step-by-step explanation:
The formula for determining the surface area of a rectangular prism is expressed as
Surface area = 2lh + 2wh + 2wl
Where
l represents the length of the rectangular prism.
h represents the height of the rectangular prism.
w represents the width of the rectangular prism
From the information given,
l = x+3
h = 5
w = x - 4
Surface area = 2 × 5 × (x+3) + 2 × (x - 4) × 5 + 2 × (x - 4) × (x + 3)
= 2(5x + 15) + 10(x - 4) + 2[x^2 + 3x - 4x - 12]
= 10x + 30 + 10x - 40 + 2x^2 - 2x - 24
= 2x^2 + 18x - 34
The answer is 27.001 because .001 comes before .002
We are given that the temperature is less than (<) -3 degrees Fahrenheit.
Since the temperature is represented by the variable "t", then t is less than -3.
So, the inequality which best describes the situation is:
t < -3
Checking the choices, we will find that the correct choice is:
<span>C: t < -3</span>
The total Surface Area of a right Cone is the sum of the area of its base and the lateral (side) surface.
The formula for the total surface area of a right cone is
Where r is the radius, and l is the slant height
