first find the length of the larger base.
Which would be the bottom in this case.
Then, find the sum of all of the sides.
It's important to note that since this is an isosceles trapezoid, both of the non-parallel sides will have the same length.
width (w) = w
Length (L) = 3w + 4
Area (A) = L x w
25 = (3w + 4)w
25 = 3w² + 4w
0 = 3w² + 4w - 25
w = 
w ≈ 2.3, w ≈ -3.6 (width cannot be negative!)
w ≈ 2.3
Length (L) = 3w + 4 = 3(2.3) + 4 = 6.9 + 4 = 10.9
Answer: width=2.3, Length=10.9
Step-by-step explanation:
(7x - 5x) -3 =x+4
2x - 3 = 2x + 7
Answer:
380
Step-by-step explanation:
1200 + 700 = 1900/5 = 380
Solution:
Let each pond of jelly beans cost $x.
and each pond of almonds cost $y.
Then we can write


Now solve these two equations together using substitution we get


Hence each pond of jelly bean cost 1.25$
Each pond of almond costs 2.25$
