Answer:

2 or -2

Step-by-step explanation:

If x² - 8x = -12

Step 1

We find x by solving

x² - 8x = -12

We equate to zero

x² - 8x + 12 = 0

We factorise

x² - 6x - 2x + 12 = 0

x(x - 6) -2(x - 6) = 0

(x - 6) (x - 2) = 0

x - 6 = 0, x = 6

x - 2 = 0, x = 2

x = 6 or 2

Step 2

What is x - 4?

When x = 6

= 6 - 4 = 2

When x = 2

= 2 - 4 = -2

Therefore, x - 4 = 2 or -2

Answer: 1inch : 10 feet

Step-by-step explanation:

Since we are informed that Mathew builds a model of a house that is 2 in tall, 6 in wide, and 3 in long while the real house is 20 ft tall, 60 ft wide and 30ft tall.

For the length, we can see that the relay house is (30/3) = 10 times the model. The same thing is applicable to others as well as the width and height is 10× the scale used. Therefore, the scale used to build the house is 1inch:10 feet

Answer:

area = 8(x + 6)

The distributive property says that the x must be added to the 6 before it is multiplied by the 8

Answer: 8(x+6)

Step-by-step explanation:

the distributive property is where you use the form

a(b+c) and area is b*h or l*w and

here 8=h   x+6=b so the equation is 8(x+6)

Hope this helps!

Step-by-step explanation:

Question b has already been answered in part one. This is an exponential function.

C) 7 is the initial number of people who received the email;

7*2^n is the number of people who receive the email on day n;

2 is the factor of which the number of people increases each day.

D) On day 5,

[tex] {2}^{5} \times 7 = 32 \times 7 =224[/tex]

people will have received the email.

E) 2; 0 (no people has received the email on day 0). The equation is

[tex]y = {2}^{x} \times 7[/tex]

With x in the natural numbers

Answer:

Below in bold.

Step-by-step explanation:

Starting height is when t = 0

It is 5 units.

To find the maximum height we convert the equation to vertex form:

h = -t^2 + 4t + 5

h = -(t^2 - 4t - 5)

=  - [(t - 2)^2 - 9]

= -(t - 2)^2 + 9

From this we see that the ball reaches max height after 2.

Maximum height = -2^2 +  4(2) + 5

= 9 units.

Ball reaches the ground after 2*2 = 4 .

Answer:

He received $16 change

Step-by-step explanation:

3 books for $18 is $24

4 DVDs for $15 is $60

His total is $84

$100 - $84 = $16

Answer:

6 dollars

Step-by-step explanation:

you multiply 3 by 8 which is 24. Then you multiply 4 by 15 and that's 70. So then you add 24 and 70 together which is 94. Lastly you subtract 94 from 100 and you get 6.

There are two baskets that weigh more than 4 but less than 6.

The weights of fruit baskets are:

4, 1, 2, 5, 5(1/2), 6

Weight is the quantity of matter in a physical body.

We can see that fruit baskets that weigh more than 4 pounds but less than 6 pounds are ones with weights of 5 pounds and 5(1/2) pounds.

So, there are two baskets that weigh more than 4 but less than 6.

Thus, there are two baskets that weigh more than 4 but less than 6.
