The factors of m2 + 12m + 35 are

Answers

You need to find 2 numbers x and y that solve the equations:

x * y = 35

x + y = 12

it looks like x = 5 and y = 7 will work

Please express exponentiation with the " ^ " symbol:

m^2 + 12m + 35

To factor this, look at the constant term and list possible pairs of factors:
1, 35
5, 7

Note that 5 + 7 = 12, which matches your middle term (12m).

5 and 7 are roots (not factors) of m^2 + 12m + 35. The corresponding factors are then (m+5) and (m+7). If you multiply these two factors together, the final result will be m^2 + 12m + 35.

What is Division?

A division is a process of splitting a specific amount into equal parts.

Given,

The temperature in potter's kiln dropped 760 degrees in 4 hours

We need to find the average of temperature drop per hour

To find this we have to divide 760 by 4.

Seven hundred sixty divided by four.

760/4

One hundred ninety

190

For an hour 190 temperature is dropped.

Hence, On average 190 temperature drop per hour.

ABCD is a rectangle. Find the length of each diagonal.AC=3(x-3)
BD=x+3

AC=___
BD=___

Answers

Answer:

Step-by-step explanation:

Ac = BD

3(x - 3) = x + 3 Distribute the 3

3x - 9 = x + 3 Subtract x from both sides

2x - 9 = 3 Add 9 to both sides

2x = 12 Divide both sides by 2

x = 6

Plug 6 back into either expression to solve for the side length

3(x - 3)

3(6-3)

3(3) = 9

x + 3

6 + 3 = 9

Answer:

AC = BD = 9

Step-by-step explanation:

the diagonals of a rectangle are congruent , then

AC = BD , that is

3(x - 3) = x + 3 ← distribute parenthesis on left side

3x - 9 = x + 3 ( subtract x from both sides )

2x - 9 = x + 3 ( add 9 to both sides )

2x = 12 ( divide both sides by 2 )

x = 6

Then

AC = 3(x - 3) = 3(6 - 3) = 3(3) = 9

BD = x + 3 = 6 + 3 = 9

that is AC = BD = 9
