What value of x makes the following equation true?
x3=-64

Answer:

b=4 makes the equation a perfect square.

Step-by-step explanation:

As long as you factorize out the equation, you'll get a result of (x+2)^2. This multiplied using foil gives you, x^2 + 2x + 4. Making it a perfect square. You could also have -2 = b which makes a perfect square, but that's not in the options.

Answer:

4

Step-by-step explanation:

The constant term 4 is obtained by

adding (half the coefficient of the x- term)²

4 = 2²

Then b = 4

x² + 4x + 4 = (x + 2)² ← a perfect square

He rowed for 4 miles

it took him 4 hours to get upstream which is 4 miles and since he can do 4 miles per hour down stream it only took him an hour to get back to the starting point which is 5 hours in total.

Answer:

Step-by-step explanation:

Volume formula:

Given:

Find the volume:

Answer :-

Total height = 4.5 × 4.5 × 4.5 = 91.125 cm

Radius = Diameter/2

Radius = 4.5/2 = 2.25 cm

Volume = πr²h

Volume = π (2.25)² × 91.125

Volume = π × 12.25 × 91.125

Volume = 1116.2 π cm³

Answer: g = -0.32

Step-by-step explanation:

Given

6 (-2g - 1) = (13g + 2)

Expand parentheses and apply the distributive property

6 · (-2g) - 6 · 1 = 13g + 2

-12g - 6 = 13g + 2

Add 12g on both sides

-12g - 6 + 12g = 13g + 2 + 12g

-6 = 25g + 2

Subtract 2 on both sides

-6 - 2 = 25g + 2 - 2

-8 = 25g

Divide 25 on both sides

-8 / 25= 25g / 25

Answer:

134°

Step-by-step explanation:

∠BAC = ∠BCA because it is an isosceles triangle

∠XCA = ∠XAC .  Congruent angles

∠XAC = 1/2(46) = 23° .  because CE bisects ∠ C

∠XCA = 23°

180° - 23° - 23° = 134° .  Sum of all angles in a triangle is 180°

Answer:

504 ft^3

Step-by-step explanation:

Ok, so we have the equation for the cylinder as well as the rectangular prism. Basically we're just going to find the volume of each of them separately and then add them together.

Let's start with the cylinder:

V(cylinder) = pi*r^2*h

pi = 3

d = 4ft

r = d/2 = 4/2 = 2ft

h = 12ft

V(cylinder) = (3)*(2^2)*(12)

V(cylinder) = 3*4*12

V(cylinder) = 144 ft^3

Now the rectangular prism:

V(rectangular prism) = l*w*h

l = 10ft

w = 6ft

h = 6ft

V(rectangular prism) = 10*6*6

V(rectangular prism) = 360 ft^3

Now we can add them together:

V(total) = 360 + 144

V(total) = 504 ft^3

Answer:

Al real numbers except 4/3

Answer:

6

Step-by-step explanation:

Initial problem:

3x - 5 = 2x + 3 - (x - 4)

First, distribute the minus sign to the parentheses:

3x - 5 = 2x + 3 - x + 4

Next, combine like terms:

3x - 5 = x + 7

Subtract x from both sides:

2x - 5 = 7

Add 5 to both sides:

2x = 12

Divide both sides by 2:

x = 6

Step-by-step explanation:

Assuming that de + ef = df, we can create the expression:

(4x + 10) + (2x - 1) = 9x - 15

Combine like terms to get:

6x + 9 = 9x - 15

The rest is basic algebra after this point.

6x + 9 = 9x - 15

-6x +15 -6x +15

______________

24 = 3x ----> x = 8

Next, plug the x value into the df equation to find df.

df = 9(8) - 15

df = 72 - 15

df = 57
