Answer:
The value of x = 15
Hence,
- BC = 2x+1 = 2(15)+1 = 30+1 = 31 in
- AC = x-3 = 15 - 3 = 12 in
Step-by-step explanation:
We know that the perimeter of a triangle is the sum of all the sides of a triangle.
Given
Perimeter = 58 in
AB = x
BC = 2x+1
AC = x-3
so the equation becomes
Perimeter = AB + BC + AC
58 = x + 2x+1 + x-3
58 = 4x - 2
4x = 58+2
4x = 60
4x/4 = 60/4
x = 15
Thus, the value of x = 15
Hence,
- BC = 2x+1 = 2(15)+1 = 30+1 = 31 in
- AC = x-3 = 15 - 3 = 12 in
VERIFICATION
Perimeter = AB + BC + AC
58 = 15+31+12
58 = 58
Answer:
Step-by-step explanation:
[4 2] * -2 5 = [ 4*-2 + 2*7 4*5+2*-1]
7 -1
= [-8+14 20-2]
= [6 18]
Answer:
0.4714, a simplified 47%
Step-by-step explanation:
:)
A flat three dimensional solid like a cube, a prism or a pyramid. When you cut out the "net", fold it and glue it together you can see what the three dimensional shape looks like. (It can be used in math)Draw a net of the polyhedron. Calculate the area of each face. Add up the area of all the faces.
The answer will be variable because of how the graph is moving up 2 then over while it changes to up 1 over 2.
