The only solution here would be x=0. Multiplying 0 to both sides results in 0=0 which is technically correct.
Answer:
A) 12.25 units
Step-by-step explanation:
From Pythagorean theorem:
Defining:
The system of equations is:
x + y = 625 (eq. 1)
36 + z = y (eq. 2)
361 + z = x (eq. 3)
Replacing equation 3 into 1:
361 + z + y = 625
From equation 2:
z = y - 36
Replacing it into equation 1:
361 + y - 36 + y = 625
2y = 625 + 36 - 361
y = 300/2
y = 150
Finally:
BC = √y
BC = √150
BC = 12.25 units

Answer:
$91
Step-by-step explanation:
They bought 7 backpacks each costing $8. Multiply them together to get $56. They filled each with $5 worth of supplies. 7 * 5 = 35. $56 + $35 = $91
