Answer:
5x+15
Step-by-step explanation:
Multiply the term outside the parentheses by each term inside the parenthesis.
5*x+5*3
5x+15
x = 43, AB = 49, BC = 49 and AC =98.
Solution:
Given data:
AC = 3x - 31 and AB = x + 6
B is the midpoint of AC.
Therefore AB = BC
.
BC = x + 6
AB + BC = AC
x + 6 + x + 6 = 3x - 31
2x + 12 = 3x - 31
Add 31 on both sides, we get
2x + 43 = 3x
Subtract 2x from both sides, we get
43 = x
AB = x + 6
= 43 + 6
AB = 49
BC = 49
AC = 3x - 31
= 3(43) - 31
= 129 - 31
AC = 98
Therefore x = 43, AB = 49, BC = 49 and AC =98.
Imagine you're cutting off all of the slanted sides, there would be 3. Now since there's 4 feet on one side and 9 on the other when you cut off the edges they have side which are 3 feet (the end number) and 2.5 (9-4=5/2=2.5) now since you have three pieces like this, so put 2 together and you get a shape which is 3feet by 2.5 feet. The area of this is 3*2.5 which is 7.5, cut that in half for the third piece and you get 3.25, added together that's 10.75 squared feet. Now don't forget the 3 by 4 and 3 by 5 pieces. That would be a total of 27 (3*4=12 3*5=15) 27+10.75=37.75 squared feet.
