a+b+c = 73 (a is shortest side, b is second shortest side, c is longest side)
c = a+b-5
c = 2a+8
b = a+13
2a+8+a+13+a = 73
4a+21=73
4a = 52
a = 13
b = 26
c = 34
However when you plug that back in, you don't get a triangle, so I think you are missing something
Answer:
4/5
Step-by-step explanation:
1 1/3 = 4/3
4/3 x 3/5
times the denominator and numerator = 12/15
divide by HCF which is 3
4/5
Type A cost $5.75 per pound
Type B cost $4.25 per pound.
Set up 2 equations:
A. + B = 174 pounds
5.75A + 4.25B = 880.50
Rewrite the first equation as A= 174 - B
Replace A in the second equation:
5.75(174-B) + 4.25B= 880.50
Use distributive property:
1000.50 - 5.75B + 4.25B = 880.50
Combine like terms:
1000.50 - 1.5B = 880.50
Subtract 1000.50 from both sides:
-1.5B = -120
Divide both sides by -1.5:
B = -120 / -1.5
B = 80
They used 80 pounds of type B
Subtract B from the total used to find type A:
174 - 80 = 94
They used 94 pounds of type A

I hope this helps! Have a nice day :)
base: b
height: b
A = 1/2 (b · b) = 1/2(b²) = b²/2
sum is six less than area
b + b = 6 - ↔b²/2
2b = b²/2 - 6
4b = b² - 12 <em>multiplied by 2 to clear the denominator</em>
0 = b² - 4b - 12
0 = (b - 6)(b + 2)
0 = b - 6 0 = b + 2
b = 6 b = -2 (Negative so disregard)
A = b²/2 = (6)²/2 = 36/2 = 18
Answer: 18 units²
