Answer:
B.) 10 cm squared
Step-by-step explanation:
Answer:
x=√-1/3 y^2 +3 or x=-√-1/3 y^2 +3
Step-by-step explanation:
Let's solve for x.
3x2+y2=9
Step 1: Add -y^2 to both sides.
3x2+y2+−y2=9+−y2
3x2=−y2+9
Step 2: Divide both sides by 3.
3x^2/3= -y^2+9/3
x^2=-1/3 y^2 +3
x=√-1/3 y^2 +3 or x=-√-1/3 y^2 +3
Hope it helped!
Answer:
14.6
Step-by-step explanation:
The area of a rectangle is area=length*width
so we can substitute the numbers here, 262.8=18w
divide 262.8 by 18 to isolate the variable.
You get 14.6.
The width is 14.6.
Answer:
no
