How many solutions does x + 2x + 7 = 3x - 7

Mathematics
1 answer:
Alex17521 [72]4 years ago
3 0

Answer:

No solutions! :)

Step-by-step explanation:

To find the number of solutions in a problem we must solve it.

x+2x+7=3x-7

Firstly, combine common terms:

3x+7=3x-7

We can subtract 3x from both sides:

7=-7

The solution is 7=-7, which is no solution.

When a number is equal to a number in a solution, it has no solutions!

<h3>Volume of a prism </h3>

From the question, we are to determine the volume of the frozen figure

In the given diagram,

The volume of the frozen figure = a³ + 1/2(a²b)

From the given information,

a = 8 cm

b = 7 cm

∴ Volume of the frozen figure = 8³ + 1/2(8² ×7)

Volume of the frozen figure = 512 + 1/2(448)

Volume of the frozen figure = 512 + 224

Volume of the frozen figure = 736 cm³

Hence, the volume of the frozen figure is 736 cm³

Write the real form of each complex equation.
Lerok [7]

Answer:

Step-by-step explanation:

Given

(a)z=4\cos (\theta )+9i\sin (\theta )

Re(z)=4\cos \theta

Im(z)=9\sin \theta

(b)z=6\cos (\theta )+i\sin (\theta )

Re(z)=6\cos \theta

Im(z)=\sin \theta

(c)z=\sqrt{5}\cos (\theta )+\sqrt{10}i\sin (\theta )

Re(z)=\sqrt{5}\cos (\theta )

Im(z)=\sqrt{10}\sin (\theta )

(d)z=5-2i+4\cos (\theta )+7i\sin (\theta )

z=5+4\cos \theta +i(7\sin \theta -2)

Re(z)=5+4\cos \theta

Im(z)=7\sin \theta -2
