I need a photo but ill give you some information this will be with exponents.

<em>Write down the problem. Here it is:</em>

<em>2^2(x+3) + 9 - 5 = 32</em>

<em>Resolve the exponent. Remember the order of operations: PEMDAS, which stands for Parentheses, Exponents, Multiplication/Division, and Addition/Subtraction. You can't resolve the parentheses first because x is in the parentheses, so you should start with the exponent, </em><em>2^2.2^2 = 4</em>

<em>4(x+3) + 9 - 5 = 32</em>

<em>Do the multiplication. Just distribute the</em><em> 4 into (x +3)</em><em>. Here's how:</em>

<em>4x + 12 + 9 - 5 = 32</em>

<em>Do the addition and subtraction. Just add or subtract the remaining numbers. Here's how:</em>

<em>4x+21-5 = 32</em>

<em>4x+16 = 32</em>

<em>4x + 16 - 16 = 32 - 16</em>

<em>4x = 16</em>

<em>Isolate the variable. To do this, just divide both sides of the equation by 4 to find x. </em><em>4x/4 = x </em><em>and </em><em>16/4 = 4</em><em>, so </em><em>x = 4.</em>

<em>4x/4 = 16/4</em>

<em>x = 4</em>

<em>Check your work. Just plug </em><em>x = 4</em><em> back into the original equation to make sure that it checks out. Here's how:</em>

<em>2^2(x+3)+ 9 - 5 = 32</em>

<em>2^2(4+3)+ 9 - 5 = 32</em>

<em>2^2(7) + 9 - 5 = 32</em>

<em>4(7) + 9 - 5 = 32</em>

<em>28 + 9 - 5 = 32</em>

<em>37 - 5 = 32</em>

<em>32 = 32</em>

SpyIntel [72]

Answer:

Step-by-step explanation:

Josh has a collection of 1,200 music CDs. He considers 1/6 of his collection rock music. This means that the number of rock music CDs that he has is

1/6 × 1200 = 200

Of the rock music CDs, 20 percent are by solo artist. This means that the number of CDs by solo artist is

20/100 × 200 = 40

Of the solo artist 2/5 are by female artist. It means that the number done by female solo artists is

2/5 × 40 = 16

QUICK!! 18x^2+21x-60=0 pls give me the steps as well
Anton [14]

Answer:

<h2>x1 =  -  \frac{5}{2}</h2>

x2 =  \frac{4}{3}

Step-by-step explanation:

18 {x}^{2}  + 21x - 60 = 0

Divide both sides of the equation by 3

6 {x}^{2}  + 7x - 20 = 0

Write 7x as a difference

6 {x}^{2}  + 15x - 8x - 20 = 0

Factor out 3x from the expression

3x(2x + 5) - 8x - 20 = 0

Factor out -4 from the expression

3x(2x + 5) - 4(2x + 5) = 0

Factor out 2x + 5 from the expression

(2x + 5)(3x - 4) = 0

When the product of factors equals 0 , at least one factor is 0

2x + 5 = 0

3x - 4 = 0

Solve the equation for X

2x + 5 = 0

Move constant to R.H.S and change its sign

2x = 0 - 5

Calculate the difference

2x  =  - 5

Divide both sides of the equation by 2

\frac{2x}{2}  =  \frac{ - 5}{2}

Calculate

x 1=  -  \frac{5}{2}

Again,

3x - 4 = 0

Move constant to RHS and change its sign

3x = 0 + 4

Calculate the sum

3x = 4

divide both sides of the equation by 3

\frac{3x}{3}  =  \frac{4}{3}

Calculate

x 2=  \frac{4}{3}

Hope this helps..

Best regards!!
