The total surface area of a regular pyramid is the sum of the areas of its lateral faces and its base. The general formula for the lateral surface area of a regular pyramid is L . S . A . = 1 2 p l where represents the perimeter of the base and the slant height.
Answer:
28 units
Step-by-step explanation:
Since, given triangles have same perimeters.

So perimeter of each triangle is 28 units
U would factor by grouping and get x^2(x-2) + 3(x-2) and then get (x^2 +3) (x-2)
Answer:
f(2) = 3
f(5/2) = 5
f(½) = -3
Step-by-step explanation:
Given the linear function f(x) = 4x - 5:
<h3>f(x) = 3</h3>
3 = 4x - 5
3 + 5 = 4x - 5 + 5
8 = 4x
8/4 = 4x/4
2 = x
Therefore, when f(x) = 3, x = 2.
<h3>f(x) = 5</h3>
5 = 4x - 5
5 + 5 = 4x - 5 + 5
10 = 4x
10/4 = 4x/4
5/2 = x
Therefore, when f(x) = 5, x = 5/2.
<h3>f(x) = -3</h3>
-3 = 4x - 5
-3 + 5 = 4x - 5 + 5
2 = 4x
2/4 = 4x/4
½ = x
Therefore, when f(x) = -3, x = ½.
First, you find what 25% of $450.To do that, make 25% into a decimal, which is 0.25.Then you multiply 450 times 0.25 which is 112.5
Second, you find what 5% of 450. 5% as a decimal is 0.05. Then you multiply 450 times 0.05 which is 22.5
Third, you add 450+112.5+22.5 which is 585.
There you go. :) Hope that helped!
