Use foil or just plain distribute

if you want foil

FOIL
First
Outer
Inner
Last
that is order to multiply dem numbers

(x+6)(x-4)
First: x times x=x²
Outer: x times -4=-4x
Inner: 6 times x=6x
Last: 6 times -4=-24

add them all together

x²-4x+6x-24
x²+2x-24

To do this, you use the FOIL method.

F: front
x*x=x^2

O: outer
x*-4=-4x

I: inner
6*x=6x

L: last
6*-4=-24

Add all those up and you get:
x^2-4x+6x-24

Which is equal to:
x^2+2x-24

Hope this helped!

One counting number is 4 times great as a counting number.The product of the two number is 36.What is the sum of the two number

VARVARA [1.3K]

Answer:

The sum of the two numbers is 15

Step-by-step explanation:

Let the counting numbers be x and y.

Then we can write the following equations

x=4y.......1 (one is four times greater )

x(y)=36.....2 (the product of the two)

Putting equation 1 into equation 2, we get

4y(y)=36

${4y}^{2} = 36$

Dividing through by 4,we get

${y}^{2} = \frac{36}{4}$

${y}^{2} = 9$

Taking square root of both side, we obtain

y=3

Putting the value of y into equation , we get

x=4(3)=12

Hence the numbers are 3 and 12

Therefore the sum of the two numbers is 3+12=15

Here’s a graph of a linear function. Write the equation that describes that function. (Zoom in if blurry)

Maru [420]

Answer: y = x/2 + 3

Step-by-step explanation:

The equation of a straight line can be represented in the slope-intercept form, y = mx + c

Where c = intercept

Slope, m = change in value of y on the vertical axis / change in value of x on the horizontal axis

change in the value of y = y2 - y1

Change in value of x = x2 -x1

y2 = final value of y

y 1 = initial value of y

x2 = final value of x

x1 = initial value of x

Looking at the graph,

y2 = 6

y1 = 4

x2 = 6

x1 = 2

Slope,m = (6 - 4)/(6 - 2) = 2/4 = 1/2

To determine the intercept, we would substitute x = 2, y = 4 and m= 1/2 into y = mx + c. It becomes

4 = 1/2 × 2 + c

4 = 1 + c

c = 4 - 1

c = 3

The equation becomes

y = x/2 + 3

There are 4 red cars and 8 black cards in a bag. How is it likely that you will randomly draw a blue card

Verdich [7]

Answer:

C) Impossible

Step-by-step explanation:

Since there are no blue cards, the probability that you'd draw one is 0/12, which means that there is no chance you'll draw one.
