Answer: (x-6)(x+1)

Step-by-step explanation:

Sum : x2 − 5 x- 6

x2 + x-=6 x − 6

factor pair: x 2 + x − 6 x − 6

x( x+ 1 ) − 6 ( x + 1 )

rewrite from: x (x + 1 ) − 6 ( x + 1 )

(x-6)(x+1)

Answer:

A: (x-6)(x+1)

Step-by-step explanation:

We need to find 2 numbers that add to make -5 and multiply to make -6.

We already have the numbers infront of us, so by process of elimination we can remove B and D.

For the numbers, we need a positive number and a negative number (two negatives make a positive). We can eliminate C because at first -3 multiplied by 2 is -6. However, when -3 is added to 2 we get -1.

If we expand A, it makes the expression that needs to be factorised because...

-6 × 1 = -6

-6 + 1 = -5

So expanding it properly we get.

x² - 6x + x - 6

Simplify.

x² - 5x -6

Evaluate - 6 – (-6) + 7 + (-4) + (-1). What’s the answer please!!

elena55 [62]

Answer:

The answer is 2.

Step-by-step explanation:

Given: - 6 - (-6) + 7 + ( - 4) + ( - 1)

= - 6 + 6 + 7 - 4 - 1

= 6 + 7 - 6 - 4 - 1

= (6 + 7) - (6 + 4 + 1)

= 13 - 11

= 2

Hence, the answer.

The perimeter of the original rectangle is ______

sergey [27]

Answer:

perimter of original rectangle = 17. 6 mm
side length of the enlarged rectangle = 23. 22 mm
perimeter of the enlarged rectangle = 95. 04 mm

Step-by-step explanation:

PERIMETER OF ORIGINAL RECTANGLE

Length of original rectangle = 4.5 mm
Width of original rectangle = 4.3 mm

perimeter = 2 × ( length + width)

= 2 × ( 4.5 + 4.3)

= 2 × 8.8

= 17. 6 mm

SIDE LENGTH OF ENLARGED RECTANGLE

Width of original rectangle = 4. 5 mm
Width of enlarged rectangle = 24.3 mm

Enlargement factor = 24.3 / 4.5

= 5.4

Length of original rectangle = 4.5 mm
Enlargement factor = 5.4

Side length of enlarged rectangle

= original length × Enlargement factor

= 4.3 × 5.4

= 23. 22 mm

PERIMTER OF ENLARGED RECTANGLE

= 2 × ( enlarged ength + enlarged breadth)

= 2 × (23. 22 + 24. 3 )

= 95. 04 mm

WRITE AN COMPOUND INEQUALITY FOR THIS SENTENCE

Mila [183]

Hello there!

Write a compound inequality for this sentence: 'w' is less than 4 and greater than or equal to -8
Only use 'w' once.

W is less than four ~ $4 \ \textgreater \ w$

W is greater than or equal to -8 ~ $w \geq -8$

If we were to put this together, it would look like:

$4 \ \textgreater \ w \geq -8$

I hope I helped!

Let me know if you need anything else!

The area of square C is 100 square units and the area of square B is 64 square units. What would be the area of square A?

rjkz [21]

Answer: The area of square A is 28 square units because the area is decreasing by 36 and the angles on each side is decreasing by 9

Step-by-step explanation:

100 divide by 4 sides = 25

64 divide by 4 sides = 16

28 divide by 4 sides = 7

SIMPLIFY 81 TO THE 1/3 POWER

Ne4ueva [31]

81^1/3. We know that 81 is 3^4, meaning 3 x 3 x 3 x 3 is 81. So (3^4)^1/3 is 3^4/3, which is 3 * (cubed root of 3).
