Answer:
(x +yi)²
Step-by-step explanation:
Comparing the given expression to the square of a binomial, we can determine the given expression to be a square.
(a +b)² = a² +2ab +b²
Here, we have a=x and b=yi. Then the factorization is ...
x² +2xyi +(yi)² = (x +yi)²
Answer:
√37
Step-by-step explanation:
the distance formula is
d = √(x2-x1)^2+ (y2-y1)^2
the x values are -4 and -5. the y values are 9 and 3. so you would plug in the x values to get -5 -(-4). double negatives make a positive, so you get -1. do the same with the y values to get -36. square those numbers to get 36 + 1 and keep the square root.
Answer:
C
Step-by-step explanation:
It's a hollow dot if its > this symbol. if you move the 3 over to the other side you get x +3 - 3 > 2 - 3 which equals x > -1
Answer:
Gross profit formula= 3x
x= number of units sold
Step-by-step explanation:
Giving the following information:
Unitary variable cost= $2
Selling price per unit= $5
<u>To calculate the profit earned, we need to use the unitary contribution margin formula</u>. The contribution margin is a product's price minus all associated variable costs (sales- variable costs), resulting in the incremental profit earned for each unit sold.
Unitary contribution margin= 5 - 2 = 3
<u>Now, the profit formula:</u>
Gross profit formula= number of units*unitary contribution margin
Gross profit formula= 3x
x= number of units sold
39 feet and 2 inches
3 times 10= 30
11 times 10= 110 in /12= 9 remainder 2
I divide by 12 cuz there's 12 inches in a foot
