4x + 2(x – 3) = 4x + 2x – 11

Answers

This problem has no real solutions. This can be irritating, because it will often make you think that you've made a mistake somewhere, but equations with variables on both sides can work out to have no real answers.

4x + 2(x - 3) = 4x + 2x - 11 Given
4x + 2x - 6 = 4x + 2x - 11 Distribute
6x - 6 = 6x - 11 Collect like terms
0 - 6 = -11 Subtract 6x from both sides
-6 = -11 This is an untrue statement, so the x is no real numbers. This can be represented as a capital R with two vertical slashes through it.

Hope this helps!

Which measure is not the area of a circle with radius 20 mm?

Answers

Given:
radius = 20 mm

Area of a circle = π r²
A = 3.14 * (20mm)²
A = 3.14 * 400mm²
A = 1,256 mm²

400mm² ; 628.57mm² ; and mm² ARE NOT THE AREA OF A CIRCLE

Answer D

Find the exact solution to the equation. Show your work. 4^(12-4x) = 256
(I know the answer is 2, the thing I don't know how to do correctly is showing my work)

Answers

Hello,

$4^(12-4x)=256\n ==\ \textgreater \ \ 2^(24-8x)=2^8\n ==\ \textgreater \ \ 24-8x=8\n ==\ \textgreater \ 8x=16\n ==\ \textgreater \ x=2$

Hi

4^(12-4x) =256
First we need to take log of both sides
log(4^-4x+12) = log (256)
(-4x + 12)(log(4)) = log(256)
so now we have
-4x + 12 = log(256)/log(4)
-4x + 12 = 4
-4x = 4 - 12
-4x = -8
x = -8/-4
x= 2

I hope that's help :)
