<span>2x^2 + 4x - 7
The given polynomial has 3 terms. They are
4x, 2x^2, and -7
The 4x term is of degree 1 with respect to x.
The 2x^2 is of degree 2 with respect to x.
and finally, the -7 term is of degree 0 with respect to x.
So sort the terms in descending order by degree and you get
2x^2 + 4x - 7
Also, don't worry that changing the order of the terms might change the value of the polynomial, that won't happen due to the commutative property of addition.</span>
The answer would be 56 4/10, or 56 2/5 simplified, because .4 into fraction form is 4/10.
Please make brainliest! ☺
I think its C but im not 100% sure.
Answer:
74.33
Step-by-step explanation:
We need to figure out the surface area. The formula for surface area is A=2πrh+2πr2
We substitute r with the radius of this cylinder and the h represents the height of this cylinder. The height we can find because we just add the diameters of the tennis balls. So 2.6*3 = 7.8. Then we get the radius, which will just be the radius of a sphere, so 1.3. Then we plug them into the formula, giving us 74.33
Answer:
Step-by-step explanation:
Using the slope from the other equation, and the point X,Y. You can get B
6=2(0)+b
B=6
The new equation is:
Y=2x+6
