Final answer:

The perimeter of triangle DEF is 24 centimeters.

Explanation:

The perimeter of a triangle is the sum of the lengths of its three sides. In this case, triangle ABC is congruent to triangle DEF, and each side of triangle ABC is 1.5 times longer than the corresponding side of triangle DEF. Let's assume the lengths of the corresponding sides of triangle DEF are x, y, and z. Therefore, the lengths of the corresponding sides of triangle ABC are 1.5x, 1.5y, and 1.5z.

Since the perimeter of triangle ABC is 36 centimeters, we can set up the equation as follows: 1.5x + 1.5y + 1.5z = 36. Simplifying the equation, we get x + y + z = 24. This means the perimeter of triangle DEF is 24 centimeters.

Answer:

The correct answer option is C) y = -2/3x - 13/3.

Step-by-step explanation:

We are given a straight line graph with one known point and we are to find its equation.

Step-by-step explanation:

In scientific notation all numbers are written in the form of m×10n (m times ten raised to the power of n), where the exponent n is an integer, and the coefficient m is any real number, called the significand or mantissa. If the number is negative then a minus sign precedes m (as in ordinary decimal notation).

Answer:

C

Step-by-step explanation:

The area (A) of the triangle is calculated using

A = [tex]\frac{1}{2}[/tex] ab sinC

where a, b are the 2 sides and C is the angle between them

here a = 6, b = 2 and C = 80°, hence

A = 0.5 × 6 × 2 × sin80° = 5.91 cm² → C

Answer:

8x³ - 5x² + 8x

Step-by-step explanation:

to solve the perimeter, you need to add all sides of the triangle together.

8x² + x³ + 2x² + 7x³ - 3x² + 6x

now, code all the similar variables:

8x² + x³ + 2x + 7x³ - 3x² + 6x

8x² - 3x² = 5x²

x³ + 7x³ = 8x³

2x + 6x = 8x

so, put them all together:

5x² + 8x³ + 8x

but remember that the larger exponent comes first(just a rule)

so, it is : 8x³ - 5x² + 8x

Simplifying

5(7x + -3) = 230

Reorder the terms:

5(-3 + 7x) = 230

(-3 * 5 + 7x * 5) = 230

(-15 + 35x) = 230

Solving

-15 + 35x = 230

Solving for variable 'x'.

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

Add '15' to each side of the equation.

-15 + 15 + 35x = 230 + 15

Combine like terms: -15 + 15 = 0

0 + 35x = 230 + 15

35x = 230 + 15

Combine like terms: 230 + 15 = 245

35x = 245

Divide each side by '35'.

x = 7

Equivalent expressions to 3.1⁴ involve raising 3.1 to the power of 4. This means 3.1 is multiplied by itself four times, not three times (which would be cubing). The equivalent expression would result from multiplying 3.1 by itself four times.

The equivalent expressions to 3.1⁴ involve the operation of raising a number to a power. In this case following the number 3.1, the exponent of 4 means that 3.1 is being multiplied by itself four times, and it is not the same as cubing. The cubing of exponentials refers to the process of raising a number to the power of three or multiplying the number by itself three times. The commutative, associative, and distributive laws can be applied to simplify and rewrite exponential expressions. Therefore, to find an equivalent expression for 3.1⁴, you would need to multiply 3.1 by itself four times.

Step-by-step explanation:

Answer:

The true statements:

- AB = 8

- x is seven units greater than y

- m∠ABC = 122°

Step-by-step explanation:

* One case of congruence is SAS that means

- If two sides and including angle between them in the first

 triangle equal to the corresponding sides and angle in the

 second triangle, then the two triangles are congruent

* In the problem

- Triangle ABC is congruent to triangle PQR using SAS case

* That means

- AB = PQ

- BC = QR

- m∠ABC = m∠PQR  

- Where angle ABC including angle between AB and BC

  and angle PQR is the including angle between PQ and QR

* Now we will use the information about the lengths of AB

 and PQ to find y, and use the measures of angles ABC and

 PQR to find x and then chose the correct answer

∵ m∠ABC = 12x + 2

∵ m∠PQR = 142 - 2x

∵ m∠ABC = m∠PQR

∴ 12x + 2 = 142 - 2x ⇒ collect the like terms

∴ 12x + 2x = 142 - 2

∴ 14 x = 140 ⇒ divide both sides by 14

∴ x = 10

* Lets substitute this value of x to find the m∠ABC and m∠PQR

- m∠ABC = 12(10) + 2 = 120 + 2 = 122°

- m∠PQR = 142 - 2(10) = 142 - 20 = 122°

∵ AB = 5y - 7

∵ PQ = 3y - 1

∵ AB = PQ

∴ 5y - 7 = 3y - 1 ⇒ collect the like terms

∴ 5y - 3y = -1 + 7

∴ 2y = 6 ⇒ divide both sides by 2

∴ y = 3

* Lets substitute this value of y to find the AB and PQ

- AB = 5(3) - 7 = 8 units

- PQ = 3(3) - 1 = 8 units

* Lets check the answer to chose the right answer

- 1st answer ⇒ AB = 8 (√)

- 2nd answer ⇒ m∠PQR = 140° (x)

- 3rd answer ⇒ y = 1 (x)

- 4th answer ⇒ x is seven units greater than y (√)

  ( x = 10 and y = 3 then x - y = 10 - 3 = 7)

- 5th answer ⇒ m∠ABC = 122° (√)

- 6th answer ⇒ PQ = 3 (x)
