If You're Good At Exact Values Please Help MeeeFind The Exact Perimeter Of This Right Angled Triangle

Answers

Answer 1

Answer:

perimeter = 14

Step-by-step explanation:

perimeter = ∑sides

                = x + (x + 3) + (x + 4)  --------eq.

                = 3x + 7

           3x = 7

            x = 7/3

plugin values into the equation:

perimeter = ⁷/₃ + (⁷/₃ + 3) + (⁷/₃ + 4)

                = 14

therefore, the perimeter of a triangle is 14

4x - 6 = x + 9

4x - 6 - x - 9 = x + 9 - x - 9        [Subtract x + 9 from both sides]

3x - 15 = 0

3x - 15 + 15 = 0 + 15                  [Add 15 to both sides]

To ensure profits, a store is going to sell a sweater for 115 percent of the production cost. It costs $10 to make the sweater. Below are the calculations for finding the selling price. What mistake did the store owner make? (Original Cost)(Percent) = New Cost ($10)(0.115) = $1.15 The new cost is correct. The owner should have divided by 0.115. The owner should have multiplied by 11.5. The owner should have multiplied by 1.15.

Answers

Answer:I did the test and the answer is The owner should have multiplied by 1.15.

Step-by-step explanation:

Sample text

To make the calculation 115 percent of the production cost , the owner should have multiplied by 1.15 to the production cost.

What is percentage?

" Percentage is defined as the hundredth part of any given number".

According to the question,

Production cost of a sweater = $10

To ensure profit , selling price = 115 percent of the production cost

(Original Cost)(Percentage)

[tex]= (10)(\frac{115}{100} )[/tex]

[tex]= $11.5[/tex]

Hence, to make the calculation 115 percent of the production cost , the owner should have multiplied by 1.15 to the production cost.

3x(x+30°) i really need help asap

Answers

A13x2+390x here is the answer

Answer:

x=15

Step-by-step explanation:

Simplifying

x + 30 = 3x

Reorder the terms:

30 + x = 3x

Solving

30 + x = 3x

Solving for variable 'x'.

Move all terms containing x to the left, all other terms to the right.

Add '-3x' to each side of the equation.

30 + x + -3x = 3x + -3x

Combine like terms: x + -3x = -2x

30 + -2x = 3x + -3x

Combine like terms: 3x + -3x = 0

30 + -2x = 0

Add '-30' to each side of the equation.

30 + -30 + -2x = 0 + -30

Combine like terms: 30 + -30 = 0

0 + -2x = 0 + -30

-2x = 0 + -30

Combine like terms: 0 + -30 = -30

-2x = -30

Divide each side by '-2'.

x = 15

Simplifying

x = 15

Given y2 + 5y - 6 = (y + p)(y +q) find the
values of p and q.

Answers

Answer:

p = 6, q = - 1

Step-by-step explanation:

Factor the left side and compare to right side

y² + 5y - 6

Consider the factors of the constant term (- 6) which sum to give the coefficient of the y- term (+ 5)

The factors are + 6 and - 1, since

6 × - 1 = - 6 and 6 - 1 = + 5, thus

y² + 5y - 6 = (y + 6)(y - 1)

Compare with (y + p)(y + q) , then

p = 6 and q = - 1
