Your gonna divide 72 by 2 so therefore you get 36
So that equals to Nicole’s age

Answer:

24 years

Step-by-step explanation:

let Donald's age be x

then Nicole's age would be 1/2 * x = x/2

now, x + x/2 = 72

3x/2 = 72

3x = 72*2

x = 144/3 = 48

Donald's age is 48, so Nicole's age is 1/2 * 48 = 24 years.

1/2(x + 1)²- 3

Ierofanga [76]

Answer:

a = 1/2
h = -1
k = -3

Step-by-step explanation:

We assume you want to compare your expression to the form ...

a(x -h)² +k

1/2(x +1)² +k

The multiplier outside parentheses is ...

a = 1/2

The horizontal offset inside parentheses is ...

-h = 1

h = -1

The vertical offset outside parentheses is ...

k = -3

Factor 7x3y4−7x2y5 completely.

Anastasy [175]

Answer:

Step-by-step explanation:

when we factor completely, we take a look at what is the biggest common factor of 7x³y⁴ and 7x²y⁵. In this case it is 7x²y⁴.

7x³y⁴-7x²y⁵ = 7x²y⁴(x-y) which is B.

Select all possible values for x in the equation x^3=375?

Helga [31]

<h2>Hello!</h2>

The answers are:

The possible values for x in the equation, are:

First option, $5\sqrt[3]{3}$

Second option, $\sqrt[3]{375}$

To solve the problem, we need to remember the following properties of the exponents and roots:

$a\sqrt[n]{b}=\sqrt[n]{a^{n}*b} \\\\\sqrt[n]{a^{m} }=a^{\frac{m}{n}}\\\\(a^{b})^{c}=a^{b*c}$

Then, we are given the expression:

$x^{3}=375$

So, finding "x", we have:

$x^{3}=375\\\\(x^{3})^{\frac{1}{3} } =(375)^{\frac{1}{3}}\\\\x=\sqrt[3]{375}=\sqrt[3]{125*3}=\sqrt[3]{125}*\sqrt[3]{3}=5\sqrt[3]{3}$

Hence, the possible values for x in the equation, are:

First option, $5\sqrt[3]{3}$

Second option, $\sqrt[3]{375}$

Have a nice day!
