If you have to compare two shapes you basically count the number of shapes there are of each type then you say for example 6:4. If they ask you to give the number of shapes to the number of shapes there are you count all the shapes and then you count the shape they asked you to find and then you will get something like 4:15

Which pair of complex factors results in a real-number product?
Crank

we will proceed to solve each case to determine the solution of the problem

we know that

i^{2} =-1

<u>case A</u>. 15*(-15i)

15*(-15i)=-225i

<u>The result of case A is not a real number product</u>

<u>case B</u>. 3i*(1-3i)

3i*(1-3i)=3i*(1)-(3i)*(3i)\\=3i-9i^{2}\\=3i-9*(-1)\\=3i+9

<u>The result of case B is not a real number product</u>

<u>case C</u>. (8+20i)*(-8-20i)

(8+20i)*(-8-20i)=8*(-8)+8*(-20i)+20i*(-8)-20i*(20i)\\=-64-160i-160i-400i^{2}\\=-64-320i-400*(-1)\\=-64-320i+400\\=336-320i

<u>The result of case C is not a real number product</u>

<u>case D</u>. (4+7i)*(4-7i)

(4+7i)*(4-7i)=4^{2} -(7i)^{2}\\=16-49i^{2}\\=16-49*(-1)\\=65\\

<u>The result of case D is a real number product</u>

therefore

<u>the answer is the option</u>

(4+7i)*(4-7i)

inysia [295]
For Beth, we know that she works 5 days a week and that she earns $54 dollars per day. Next, add the $10 dollars for each extra hour of work. p stands for the amount she gets paid.
(54 * 5) + (10 * x) = p
 
 For Ray, do exactly the same things you did for Beth but put in his earnings.

(60 * 5) + (8 * x) = p
