Select all expressions that are equivalent to x2 - 4x - 32.
(x - 16)(x + 2)
(x + 2)(x - 16)
(x - 8)(x + 4)
(30+8)(x – 4)
(x + 4)(x - 8)
(x – 4)(x + 8)

Answers

Answer:

(x - 8)(x + 4)

(x + 4)(x - 8)

Step-by-step explanation:

(x - 16)(x + 2)

= x2 + 2x - 16x - 32

= x2 - 14x - 32

(x + 2)(x - 16)

= x2 - 16x + 2x - 32

= x2 - 14x - 32

(x - 8)(x + 4)

x - 8)(x + 4) = x2 + 4x - 8x - 32

x - 8)(x + 4) = x2 + 4x - 8x - 32 = x2 - 4x - 32

( 30 + x)(x - 4)

= 30x - 120 + x2 - 4x

= x2 + 26x - 120

(x + 4)(x - 8)

(x + 4)(x - 8) = x2 - 8x + 4x - 32

(x + 4)(x - 8) = x2 - 8x + 4x - 32 = x2 - 4x - 32

(x - 4)(x + 8)

= x2 + 8x - 4x - 32

= x2 + 4x - 32

A rectangle has a height of 5% and a width of 2 + 2.

Answers

Answer:

A rectangle has a height of 5 and a width of x² + 2

To find out:

Express the area of the emotive rectangle?

Formula used:

Area of rectangle = Length × Breadth.

Solutions:

Length = 5 and Breadth = x² + 2

We know that:

Area of rectangle = Length × Breadth.

Substitution the value of Length × Breadth.

= 5 × (x² + 2)

= 5x² + 10

Hence, the area of the emotive rectangle is 5x² + 10

•Monomials: expressions with single terms are called monomials.

• Binomial: expressions with two terms are called binomials.

• Trinomial: expressions with 3 terms is called trinomial.

• Multinational: expression with Tu are mo terms are called Multinational.

GI=15

Step-by-step explanation:

GI=12+3= 15

I hope I helped you^_^

Hi! I'm happy to help.

To solve this we need to know what is happening. This line segment was split into two parts by H. GH (part 1) and HI (part 2).

These two parts together equal the total length of the line segment. We learn that GH is 3, and HI is 12.

12+3=15

Now, we know that GI has a length of 15.

I hope this was helpful, keep learning! :D

Answers

Answer:

$17.25

Step-by-step explanation:

The tip is 15% of $15.00, or 0.15 * 15 = $2.25

We add that to the meal's cost, which is $15.00

15.00 + 2.25 = 17.25

​

Answers

Answer:

Step-by-step explanation:

ab² + 2a²b + a³ = a(b² + 2ab + a²)

Here variable 'a' is common in all the terms. HCF = a

2) 2ab² = 2 * a * b *b

   4a²b = 2 * 2 *a * a * b

6a³        = 2 * 3 * a * a * a

HCF = 2a

2ab² - 4a²b - 6a³ = 2a(b² - 2ab - 3a²)

Find the probability of “landing” in the shaded region of the figures below. Round your answer to the nearest hundredth.

Answers

Answer:

#4

Area of rectangle:

A = lw = 10*20 = 200 m²

Shaded area:

A = 2πr² = 2π(10/2)² = 157.079 m²

Probability:

P = 157.079/200 ≈ 0.785 or 78.5%#5

Area of bigger circle:

A = πr² = π(20)² = 1256.637 m²

Shaded area:

A = π(10² - 5²) = 235.619 m²

Probability:

P = 235.619/1256.637 ≈ 0.187 or 18.7%

Answer:

4

We know that

Area of rectangle = lb

Area = 10(20)

Area = 200 m²

Shaded region = πr²

=> 2 × 22/7 × (10/2)²

=> 2 × 22/7 × 10/4

=> 157 m²

Probability = 157/200 = 78.5%

5.

Area of the biggest circle = πr²

= 22/7 × (20)²

= 1256.6

Area of shaded region

π(10² - 5²)

π(100 - 25)

3.14(75)

235.6

Probability = 235.6/1256.6 = 18.7%

6 + 4w = 2w − 6
Solve for W

Answers

Answer: w= -6

When we subtract 2w from both sides we get 2w on the left and 0 on the right. The equation becomes 6+2w=-6. Then we subtract both sides by 6 making it 2w=-12 and when we divide each side by 2 we get w=-6

Answer:

W=-6

Step-by-step explanation:

6+4w=2w-6

Collect Terms

4w-2w=-6-6

2w=-12

now divide both sides by 2

2w/2=-12/2

w=-6

one third of a number plus 6 is 12

Answers

I think it’d be 2? You think about this and see if you agree. 6+6 is 12 and 1/3 of 6 is 2. Therefore I think the answer would be 2

The line passing through points (5,) and (2,−3) is parallel to a line with a slope of 4/3. What is the value of y?

Answers

Answer:

Step-by-step explanation:

Parallel lines have same slope

Slope = [tex]\dfrac{y_{2}-y_{1}}{x_{2}-x_{1}}[/tex]

[tex]\dfrac{-3-y}{2-5}=\dfrac{4}{3}\\\\\\\dfrac{-3-y}{-3}=\dfrac{4}{3}\\\\\\-3-y=\dfrac{4}{3}*(-3)\\\\\\[/tex]

-3-y = 4*(-1)

-3 - y = -4

- y = - 4 + 3

-y = -1

Divide both sides by (-1)

y = 1

Show work I need help

Answers

Answer:

a = -9

Step-by-step explanation:

8a=4(a-9)

Divide each side by 4

8a/4=4(a-9)/4

2a = a-9

Subtract a from each side

2a-a = a-9-a

a = -9

Answer:

-9

Step-by-step explanation:

8a = 4(a-9)

Use the distributive property (Multiply 4 times a, and 4 times -9)

8a = 4a - 36

Bring the 4a to the other side

8a - 4a = -36

Add like terms

4a = -36

Divide both sides by 4 to get a by itself

a = -9
