Answer:
2(12x-1)
Step-by-step explanation:
expand the expression
24x-12+10
add the constants
24x-2
take out 2, since it is common
2(12x-1)
By definition we have:
A triangular pyramid (also called tetrahedron) is a polyhedron whose surface is formed by a base that is a triangle and triangular lateral faces that converge in a vertex that is called apex (or apex of the pyramid).
It will be composed, therefore, by 4 faces, the triangular base and three lateral triangles that converge at the vertex.
Thus, the surface area is:
As = 4 * (50.5) = 202 in ^ 2
Answer:
The total surface area of the triangular pyramid is:
202 in ^ 2
Answer:
x=35
y=34
Step-by-step explanation:
x+y=-1
x+3y=67
x=-3y+67
-3y+67+y=-1
-2y+67=-1
-2y=-68
y=34
x=-35
Total amount paid by Rita is $98.79
Step-by-step explanation:
- Step 1: Given sales tax = 11% and cost of jeans = $89
- Step 2: Calculate amount of sales tax = 11% of 89 = 11/100 × 89 = $9.79
- Step 3: Calculate the total amount
Total Amount = 89 + 9.79 = $98.79
Largest integer: 57
x + x + 1 + x + 2 = 168
3x + 3 = 168
-3 -3
3x = 165
/3 /3
x = 55
x = smallest integer = 55
x + 1 = middle integer = 55 + 1 = 56
x + 2 = largest integer = 55 + 2 = 57
