Answer:
x=10
Step-by-step explanation:
these are similar triangles
8 12
------ = -----------
x+4 2x+1
using cross products
8* (2x+1) = 12(x+4)
distribute
16x + 8 = 12x+48
subtract 12x from each side
16x-12x +8 = 12x-12x+48
4x+8 = 48
subtract 8 from each side
4x+8-8 = 48-8
4x = 40
divide by 4
4x/4 = 40/x
x =10
Answer:
1 + 1 = 2
Step-by-step explanation:
2+2=4
hope it helps
Answer:
the numbers are 20, 21 and 22
Step-by-step explanation:
x+(x+1) + (x+2) = 63
3x +3 = 63
3x = 60
x = 20
doing this for ponits
it could be like 1/4 2/4 and maybe any number that is dealing with the numbers 4
