Answer:
72a
Step-by-step explanation:
Answer: CD = 10
Identify the given information.
FG = 15
GE = 21
FE = 36
CD = x
DE = x + 4
Form your equation. Due to the Side-Splitter Theorem, FG/GE = CD/DE.
15/21 = x/x + 4
Cross-multiply and solve.
15(x + 4) = 21x Distributive Property
15x + 60 = 21x Subtract 15x from both sides
60 = 6x Divide by 6 to both sides
x = 10 Answer!
88 multiplied by 106 is 9328 and move two decimal spaces to the left wich is 93.28% :)
Its (x+3)(x+4)=5 , the third one
