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

Subtract 10 from each side

Multiply each side by -4/3

-3/4z * -4/3 = -2 *4/3

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

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

8a=4(a-9)
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

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

15.00 + 2.25 = 17.25

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

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%
