Although x ² and x both have the variable x, you can’t add them together. So x + x + x + x is 4x and we just leave x ² the same. So the simplified expression is x ² + 4x. I hope this helped!!

Solve for x: −3x + 3 −1 b. x −3
Svet_ta [14]

Answer:

2/3

Step-by-step explanation:

Your −3x + 3 −1 is not an equation and thus has no solution.

If, on the other hand, you meant

−3x + 3 = 1

then -3x = -2, and  x = 2/3

Find all real numbers z for which the equation (z-5)x^2-zx+5=0 only has one real solution. Please help!! I am giving Brainliest!
frutty [35]

Answer:

z = 5

x = 0

x = 1

Step-by-step explanation:

(z - 5)x^2 - (z - 5)x = 0          Take out z - 5 as a common factor

(z - 5)(x^2 - x)                        Take out x as a common factor

(z - 5)(x)(x - 1)                          Any one of these could equal 0. There are 3 solutons.

z - 5 = 0                                  Add 5 to both sides

z - 5 + 5 = 0 + 5

z = 5

===============

x = 0

===============

x - 1 = 0

x - 1 + 1 = 0 + 1    

x = 1

==============

The age of a mother is three times the age of her son. If the difference between their
diamong [38]

Answer:

Mother = 30\ years

Son = 10\ years

Step-by-step explanation:

Given

M = Mother

S = Son

From the first statement:

M = 3S

From the second:

M - S = 20

Required

Find M and S

We have:

M = 3S and

M - S = 20

Substitute M = 3S in M - S = 20

3S -S =20

2S = 20

Divide both sides by 2

S = 10

Substitute S = 10 in M = 3S

M = 3 * 10

M = 3 0

Hence;

Mother = 30\ years

Son = 10\ years
