Answer:
2x^2-4x=3
standard form of a quadratic equation =ax^2+bx+y=0
so you would bring the 3 over to the other side making the solution 2x^2-4x-3=0
In the equation for surface area the radius is squared ( r^2)
If the radius is doubled, the radius would be 2^2 more which equals 4
The surface area would be 4 times the old surface area.
Answer:
23
Step-by-step explanation:
plug and chug: 5(4)+3=20+3=23
I dont know what you're asking, the property? That is distributive, and the answer of the expression is 7y+35
1st one is true and second one false.
