U would subtract to find the unknown term
Answer:
all i know is that the answer is
above 2,400
Step-by-step explanation:
X+5y=4
2x+10y=8
x=<u>-5y+4
</u>2(-5y+4) +10y=8 substituted in the equation for x
-10y+8+10y=8 distributed
<u />8=8 combined like terms (-10y+10y)
0=0

When you have a right triangle, you can use the Pythagorean Theorem to find the missing side length. (this can only be used for RIGHT triangles)
Pythagorean Theorem:
a² + b² = c² [c is the hypotenuse, or the longest line]
Since you know b = 8 and c = √73, plug it into the equation
a² + 8² = (√73)²
a² + 64 = 73
a² = 9
a = √9
a = 3
