OK my paper says the numerical expression 5+12 represent the sum of 5 and 12. I don't understand

Which answer is correct?

dalvyx [7]

(x-p)(x-q)
x^2 -qx -px + pq
x^2 -(q+p) x +pq
so the constant here is the product of p & q
the answer is A

The ratio of red jellybeans to yellow jellybeans to blue jellybeans in a bowl is

miv72 [106K]

Answer:

see explanation

Step-by-step explanation:

Sum the parts of the ratio, that is 3 + 2 + 5 = 10

Divide the total jellybeans by 10 to find the value of one part of the ratio

80 ÷ 10 = 8 ← value of 1 part of the ratio, thus

red jellybeans = 3 × 8 = 24

yellow jellybeans = 2 × 8 = 16

blue jellybeans = 5 × 8 = 40

What is the relationship between a cylinder and a sphere with the same base area and perpendicular height?

grin007 [14]

Answer:

For a sphere, the height is equal to the diameter, or two times the radius.

and because both objects have the same base area, then we can take the radius of the sphere equal to R and the radius of the base of the cylinder also equal to R.

The volume of the cylinder is:

Vc = pi*r^2*h

and here we have r = R and h = 2R

V = pi*(R^3)*2

the volume of a sphere of radius R is:

Vs = (4/3)*pi*R^3

The quotient between them is:

Vc/Vs = 2/(4/3) = 6/4 = 3/2.

This means that the volume of the cylinder is 3/2 times the volume of the sphere, always, for any value of R.

Question 1

Sphinxa [80]

Answer:

No

Step-by-step explanation:

x^3• x^3•x^3

We add the exponents

x^(3+3+3) = x^9

x^3•3•3 x^3 *9

9x^3

These are not equal unless

x^9 = 9x^3
