Answer and Explanation

Step-by-step explanation:

The fraction 4/5 is a rational number. Rational numbers result when one integer is divided by another. both four and five are integers.

Answer:

See below.

Step-by-step explanation:

The converse of the Pythagorean Theorem tells us that if the sum of the square of the two shorter lengths is equivalent to the square of the longest length, then the triangle is indeed a right triangle.

We have the side lengths (x²-1), (2x), and (x²+1).

We can see that our hypotenuse will be (x²+1), since it will always yield the largest value for x.

So, we can use the Pythagorean Theorem:

[tex]a^2+b^2=c^2[/tex]

Substitute (x²-1) and (2x) for a and b, and substitute (x²+1) for c:

[tex](x^2-1)^2+(2x)^2\stackrel{?}{=}(x^2+1)^2[/tex]

Square each expression:

[tex](x^4-2x^2+1)+(4x^2)\stackrel{?}{=}(x^4+2x^2+1)[/tex]

Combine like terms:

[tex]x^4+(-2x^2+4x^2)+1\stackrel{?}{=}(x^4+2x^2+1)[/tex]

Add:

[tex]x^4+2x^2+1\stackrel{\checkmark}{=}x^2+2x^2+1[/tex]

We can see that the resulting equations are equivalent, proving that the triangle is indeed a right triangle.

And we're done!

Answer:

9

Each value is 3 times the number on the ratio.

10 x 3 = 30.

So, the ratio for oranges would be 9 because:

3 x 3 = 9.

So, the answer is 9.

Answer:There are three steps. The steps are at 8 from 0 to 1, at 12 from 1 to 2, and at 16 from 2 to 3. Closed circles are on the left side of each step, and open circles are on the right.

Answer:

Morgan would need 8 gallons of paint to cover 2800 ft^2

Step-by-step explanation:

Write and solve an equation of ratios:

  x           2800 ft^2

--------- = ----------------

5 gal       1750 ft^2

Cross-multiplying yields 1750x = 14000, and so x = 8

Morgan would need 8 gallons of paint to cover 2800 ft^2

Answer:

[tex]f(x)*g(x) = x^2+3x-28[/tex]

Step-by-step explanation:

[tex]f(x) = x+7\\g(x) = x-4\\\\f(x) * g(x) = (x+7) * (x-4)[/tex]

To solve a multiplication of 2 parenthesis, we'll multiply each of the terms on the left with each of the terms on the right. Then, add all of the products together.

First, x (left) with x (right):

[tex]x * x = x^2[/tex]

Next, x (left) with -4 (right):

[tex]x * (-4) = -4x[/tex]

Next, 7 (left) with x (right):

[tex]7 * x = 7x[/tex]

Finally, 7 (left) with -4 (right):

[tex]7 * (-4) = -28[/tex]

Now we have 4 products. To find the result of the entire expression, we need to add all of these together.

[tex]x^2 - 4x + 7x - 28[/tex]

We can simplify -4x+7x to 3x:

[tex]x^2 + 3x-28[/tex]

Answer: [tex]f(x)*g(x) = x^2+3x-28[/tex]

Answer:

[tex] \longmapsto f(x) = x + 7 \\ \longmapsto g(x) = x - 4 \\→ f(x)g(x) = (x + 7)(x - 4) \\ = {x}^{2} - 4x + 7x - 28 \\ = \boxed{ {x}^{2} + 3x - 28}✓[/tex]

Hello! My name is Chris and I’ll be helping you with this problem.

Date: 9/27/20  Time:  8:58 pm CST

Answer:  

A = 4

Explanation:

Step 1: Write out the equation

2 + a/4 = -1

Step 2: Solve

Add 2 to both sides of the equal sign

a/4 = 1

Multiply 4 on both sides

a = 4

I hope this helped answer your question! Have a great rest of your day!

Answer:

Liliana surveyed 20 students that how many hours they spend on their computers each week.

The results are as follows

8, 15, 0, 11, 12, 13, 16, 13, 0, 4, 17, 14, 30, 13, 5, 12, 1, 13, 12, 21

In the above results 2 students did not use computers out of 20 students.

Therefore, The total number of students who used their computers = 20 - 2 = 18

So the ratio would be 18 : 20 or 9 : 10

Answer:

Ratio would be 9 : 10

Answer:

f = 15

Step-by-step explanation:

15 + 6f = 7f

subtract 6f from each side

15= 1f

15=f

Answer:

15

Step-by-step explanation:

15 +6f =7f

15 =7f - 6f

15 =f

Answer: y=3

Step-by-step explanation: 6(4.5y−12)=9

Step 1: Simplify both sides of the equation.

6(4.5y−12)=9

(6)(4.5y)+(6)(−12)=9(Distribute)

27y+−72=9

27y−72=9

Step 2: Add 72 to both sides.

27y−72+72=9+72

27y=81

Step 3: Divide both sides by 27.

27y/27 =81/27
