Answer:
3.25 spaces, but you need to tell me how big the spaces are
The area of the base is given by:
A1 = (1/2) * (15) * (13)
A1 = 97.5
The area of the lateral faces is given by:
A2 = (1/2) * (15) * (10)
A2 = 75
Then, the total surface area is:
A = A1 + 3A2
Substituting values:
A = 97.5 + 3 * (75)
A = 322.5
Answer:
The surface area of the equilateral triangular pyramid is:
C) 322.5 in2
Answer:
-x2 + 2x + 8
Step-by-step explanation:
Your first step will be to set up the problem:
f(x) - g(x)
Next, you will substitute in your values:
(2x + 1) - (x2 - 7)
The easiest way to do the subtraction problems is to distribute your negative into your second set of parenthesis, so your expression would become:
2x + 1 - x2 + 7
Then combine your like terms:
2x - x2 + 8
Lastly, put your expression in standard form (highest exponent to lowest)
-x2 + 2x + 8
