What is the factored form of x2 − 4x − 5?

laiz [17]

Factored Form:
x^2 - 4x - 5
Simplifying:
x^2 + - 4x + - 5 = 0

Reorder the terms:
- 5 + - 4x + x^2 = 0

Solving for variable " x":
Subproblem 1:
Set the factor ( - 1 + - 1x) equal to Zero and attempt to solve.

Simplifying:
- 1 + - 1x = 0

Solving:
- 1 + - 1x = 0
Move all terms containing x to the left, all other terms to the right

Add 1 to each side of equation:
- 1 + 1 + - 1x = 0 + 1

Combine Like Terms: 0 + 1 = 1
x = - 1

Divide each side by - 1
x = - 1

Simplifying: x = - 1

Subproblem 2: Set the factor (5 + - 1x) equal to Zero attempt to solve

Simplifying:
5 + - 1x = 0

Move all terms containing x to the left, all other terms to the right
Add - 5 to each side of the equation
5 + - 5 + - 1x = 0 + 5

Combine Like terms: 5 + - 5 = 0
0 + - 1x = 0 + - 5
- 1x = 0 + - 5

Combine Like Terms: 0 + - 5 = - 5
- 1x = - 5

Divide each side by - 1
x = 5

Simplifying:
x = 5

Solution:
x = { - 1, 5}

Answer when factored:
(x + 1)(x - 5)

hope that helps!!!

Fred has 36 strawberries and 42 blueberries. He wants to use them to garnish desert so that each desert has the same number of b

DENIUS [597]

To do this problem you must find the GCF or the greatest common factor of 36 and 42. For example 36 can be made by 1 and 36 2 and 18 3 and 12 4 and 9 and 6 and 6. 42 can be made by 1 and 42 2 and 21 3 and 14 and 6 and 7. The highest common factor is 6. So, if you put 6 berries on all of the desserts, you will put 6 strawberries on 6 tarts and 6 blueberries on 7 tarts. That’s a total of 13 desserts

The isosceles trapezoids, ABCD and EFGH, are similar quadrilaterals. The scale factor between the trapezoids is 2:3, = 6 centime

Bingel [31]

Answer:

Part A) see the explanation

Part B) see the explanation

Part C) The perimeter of trapezoid ABCD is 32 centimeters and the perimeter of trapezoid EFGH is 48 centimeters

Step-by-step explanation:

The complete question is

The isosceles trapezoids, ABCD and EFGH, are similar quadrilaterals. The scale factor between the trapezoids is 2:3, GH = 6 centimeters, AD = 8 centimeters, and AB is three times the length of DC

Part A) Write a similarity statement for each of the four pair of corresponding sides

we know that

If two figures are similar, then the ratio of its corresponding sides is proportional

The corresponding sides are

AB and EF

BC and FG

CD and GH

AD and EH

so

$\frac{AB}{EF}=\frac{BC}{FG}=\frac{CD}{GH}=\frac{AD}{EH}$
