Answer:

x+2

Step-by-step explanation:

Dividing the poly by the known factor:

x3+5x2+6x <u>| x2+3x</u>

-x3-3x2 x + 2 <- the answer is here

2x2+6x

-2x2-6x

To prove that, let's multiply the two factors and find the pylonomial back on:

(x2+3x).(x+2) = x3 + 2x2 + 3x2 + 6x = x3 + 5x2 + 6x

Tks your attention!

Answer:

B: 24ft^2

Step-by-step explanation:

Area of triangle = (base x height)/2

Step 1: form an equation

a = (12ft x 4ft)/2

Step 2: solve equation

a = 48ft^2 / 2

a = 24ft^2

*the base is the measurement for the bottom of a triangle while height is the measurement of the length from the bottom to the top of a triangle*

what is the point slope form of an equation with the slope of 3/5 that passes through the point (10,-2)?

Mama L [17]

Point slope form of a line:
$y-y_1=m(x-x_1)$ where $m$ is your slope and $(x_1,\ y_1)$ is a point on your line.

For a line with a slope of 3/5 that passes through (10, -2)...
$m=\frac35,\ x_1=10,\ y_1=-2$
Let's plug these values into our formula.

$y-(-2)=\frac35(x-10)$

Subtracting by a negative is the same thing as adding (the double negatives cancel), so let's simplify that.

$\boxed{y+2=\frac35(x-10)}$

There's our equation in point-slope form. (keep in mind that you're not going to want to distribute that 3/5 or subtract the 2 or anything. You want to keep it similar to the formula.

A quality control inspector found that 1.3% of 1500 computers inspected were defective. How many computers were defective?

Lilit [14]

Given that percent of computer infected which is found by quality control inspector = 1.3%

Total number of computers = 1500

Now we have to find the number of Defective computer. To find that we will just need to find the product of given defective percent by the total number of computers.

Total number of defective computers = 1.3% of 1500

Total number of defective computers = 0.013* 1500

Total number of defective computers = 19.5

Hence final answer is approx 20 computers.

The cost of manufacturing a printer is $35. The

Gelneren [198K]

Answer:

$47.25

Step-by-step explanation:

First, we find how much the markup costs:

35%=35/100

So we do,

35/100x$35 = $12.25

To find the total price of everything, we have to add the price markup AND the original cost of the printer.

So we do, 35 + 12.25 = $47.25

I hope this helps!:)
