Answer: 210
Step-by-step explanation: Since we are trying to find what 3/5 of a number gives you 126 You would divide 126 by 3 which equals 42 then you would add 126+42+42=210
Answer:
none of the above
Step-by-step explanation:
Inches beacause feet would be too much and centimeters would be too small
X²/25 + y²/100 =1
4x²/100+ y²/100 =1
4x²+y²=100
y²=100- 4x²
If x=0, y²= 100, y = ±10
c{(0,-10),(0,10)}
If y=0, 4x²= 100, x²=25, x=±5
d {(-5,0),(5,0)}
