Which expression is equivalent to (3y+3) +(y^2 -1) +2y+(y^2+2)

1 answer:

8 0

The way I looked at this was the amount of y² s in the expression. There is one fro the second bracket and one from the third so the equivalent expression must have 2y². Therefore the answer must be C

Which container holds the most?

goldenfox [79]

Cylinder:

V = pi * r^2 * h

V = 3.14 * 9^2 * 11

Simplify exponent:

V = 3.14 * 81 * 11

Multiply:

V = 2797.74

Sphere:

V = 4/3 * pi * r^3

V = 4/3 * 3.14 * 9^3

Simplify exponent:

V = 4/3 * 3.14 * 729

Multiply:

V = 3052.08

Cone:

V = 1/3 * pi * r^2 * h

V = 1/3 * 3.14 * 12^2 * 20

Simplify exponent:

V = 1/3 * 3.14 * 144 * 20

Multiply:

V = 3014.4

So the Sphere holds the most.

Solve the equation 2x^2+15x^2

pishuonlain [190]

Answer: you can only add like terms, for example; 2x + 3x = 5x as they both have an x next to the numbers.

you cannot simplify 2 + 4x as they both don’t have an x next to them.

hence why, the answer to 2x^2 + 15x^2 would be 17x^2
