Answer:

The suppliers tank won't deliver enough water.

Step-by-step explanation:

Hernando needs at least 75 gallons of water . His supplier has a cylindrical model that has a diameter of 2 ft and height of 3 ft. The volume of water at which his supplier tank can accommodate can be computed as follows .

Since the suppliers model is a cylinder we will use volume of a cylinder formula.

volume = πr²h

where

r = radius = 2/2 = 1 ft

h = height = 3 ft

volume = π × 1² × 3

volume = 3.14 × 3

volume = 9.42 ft³

The suppliers volume of water is 9.42 ft³ and Hernando needs at least 75 gallons of water.

Since

0.1337 ft³ = 1 gallon of water

9.42 ft³ = ? gallon of water

cross multiply

gallon of water = 9.42/0.1337

gallon of water = 70.4562453254

gallon of water = 70.47 gallons.

The suppliers tank won't deliver enough water.

If x=0 and x=3 then 3 divided by 2x to the second power minus 2 divided by x to the second power minus 3x

Answer: undefined in both cases.

Explanation:

1) Expression to evaluate:

$\frac{3}{2x^2} - \frac{2}{x^2-3x}$

2) You are asked to evaluate that expression for two different cases, x = 0 and x = 3.

3) First case: x = 0

The expression cannot be evaluated at x = 0, because the denominators (both denominators) equal 0, and the division by 0 is not defined.

So, the answer is undefined.

4) Second case, x = 3

When you replace x = 3 you get:

$\frac{3}{2x^2} - \frac{2}{x^2-3x} = \frac{3}{2(3^2)} - \frac{2}{3^2-3(3)} = \frac{3}{18} - \frac{2}{9-9}$

Again, this result in a division by 0, so you conclude that it is undefined too.

4 to 7
or
4+7= 12
4x+7x=33
x=3
so,
(4×3)+(7×3)=33
12+21=33
or
12 and 21.
