Answer:
X= 7
Step-by-step explanation:
x+x+2+3x-6=31 Combine x's
2x+2+3x-6=31 Continue to combine x's
5x+2-6=31 Combine whole numbers
5x-4=31 Add 4 to both sides
5x=35 Divide by 5
x=7
Answer:
AE = 18 units
Step-by-step explanation:
Δ AEB and Δ DEC are similar , then corresponding sides are in proportion, that is
= , substitute values
= ( cross- multiply )
10(2x + 4) = 12(x + 8) ← distribute parenthesis on both sides
20x + 40 = 12x + 96 ( subtract 12x from both sides )
8x + 40 = 96 ( subtract 40 from both sides )
8x = 56 ( divide both sides by 8 )
x = 7
Then
AE = 2x + 4 = 2(7) + 4 = 14 + 4 = 18 units
