The product (x-10) (x + 2)

Karolina [17]

Answer :

To find the product of (x + 8)(x – 10)

We know that

(x + a)(x + b) = x2 + (a + b)x + ab

In the expression (x + 8)(x – 10)

a = 8

b = -10

a + b = 8- 10 = -2

ab = 8 × (-10) = – 80

Substitute the values in the above equation

(x + 8)(x – 10) = x2 + (8 – 10)x + 8 × (-10)

(x + 8)(x – 10) = x2 – 2x – 80.

Thank you !

NEED HELP PLZ The following table shows the number of hours some students in two neighborhoods spend walking to school each wee

Leni [432]

Firstly, order the two data set from smallest to largest as shown in diagram below

The value of median, Q2 is the 5th value of both set
The value of Q1 and Q3 is the first and third quarter of the set
The range of data set one is 5-2=3 and of set two is 12-1=11
The interquartile range of set one is 5 - 2 = 3
The interquartile range of set two is 5 - 1.5 = 3.5

The box plot is not symmetrical for either data set

X-3y=6<br> x=3y+4<br><br> solve for x and y

Fantom [35]

Answer:

1) x = 6, y = -2 + 1/3x

Step-by-step explanation:

1) x-3y=6

-3y=6-x, 6-x/-3y

y = -2 + 1/3x

x - 3(-2+1/3x) = 6

x - 6 + x = 6

2x =12

x = 6

2) x=3y+4

-3y = -x+4

y = -x/-3 +4/-3

y = 1/3x + -4/3

x = 3(1/3x + -4/3)

I am unsure about x on number two...
