9514 1404 393

Answer:

  x = 12

Step-by-step explanation:

Sides of similar figures are proportional, so ...

  AB/FE = BC/EC

  x/6 = 10/5

  x = 6·(10/5) . . . multiply by 6

  x = 12

ABCD is a parallelogram and this figure is NOT drawn to scale.
dimulka [17.4K]
The angle does not matter. Think of it as finding the other side to a triangle. Use a ^{2} +b^2 =c^2

a=39 (line AB)
b=b (the leg we need to find)
c=89 (line BD)

39^2 + b^2 = 89^2
1521 + b^2 = 7921
(subtract the 1521 from both sides)
b^2 = 6400
(square root both sides)
\sqrt{(b^2)} =  \sqrt{6400} 


b = 80
AD=80

This year, the Newville Tigers won six games more than the Wilton Panthers won. The Tigers won 22 games. Which equation cannot b
Usimov [2.4K]

Answer:

The ones that can be used are (B and A)

The ones that cannot be used are (C and D)

Step-by-step explanation:

Because the panthers got 6 less and the tigers got 22…

b+6 would make 22 (panthers plus 6 makes tigers)

22-b would also be 6 because 6+b makes 22, so subtracting b from 22 makes 6

Combine the like terms to create an equivalent expression. 5 + 9t + 3
nikdorinn [45]

Answer:

9t + 8

Step-by-step explanation:

9t + (5+3)

Think of it like this. You have 9 oranges, 5 grapes, and 3 grapes. How many grapes and oranges do you have?

Math wise, we will have t representing oranges, and the normal numbers representing grapes. All you have to do is combine them using whatever sign separates them. If you need more help, let me know.
