Answer:

The correct answer is P = 24 + 8x.

Step-by-step explanation:

First, we must express the length and width of the frame.

Length = 7 + 2x

Width = 5 + 2x

The perimeter is the sum of the four sides of the frame.

P = 2 * (7 + 2x) + 2 * (5 + 2x)

P = 14 + 4x + 10 + 4x

P = 24 + 8x

In this way, we express the perimeter (P) of the frame.

Have a nice day!

Choose the correct simplification of 8x2(5x 2x2 − 3). 16x4 − 40x3 24x2 16x4 40x3 − 24x2 40x4 16x3 − 5x2 40x4 − 10x3 5x2

The correct simplification of 8x2(5x 2x2 − 3) is 16x^{4} +40x^{3} -24x^{2}

<h3>What do you mean by simplification?</h3>
  • Simplifying procedures is one way to achieve uniformity in work efforts, expenses, and time. It reduces diversity and variety that is pointless, harmful, or unnecessary.
  • Making anything simpler is the act or process of simplification. Everyone is in favor of streamlining court procedures.
  • Certain "solving" issues are connected to "simplification" issues. Parentheses and even nested grouping symbols can be found in some equations, just like in some expressions. Whether we're working with equations (so we're also solving) or expressions (and only simplifying), the simplification procedure is the same in both cases.

The correct simplification of 8x2(5x 2x2 − 3).

8x^{2} (5x+2x^{2+1} -3)=8*2x^{2+2} -8*3x^{2}

                                =40x^{3} +16x^{4} -24x^{2}

Rearranging the above expression in descending order of power, we get:16x^{4} +40x^{3} -24x^{2}

The correct simplification of 8x2(5x 2x2 − 3) is 16x^{4} +40x^{3} -24x^{2}

Solve for the two acute angles
sineoko [7]

Answer:

Angle A = 37 degrees, and Angle B = 53 degrees.

Step-by-step explanation:

We know that this is a right triangle, where angle C is 90 degrees. Since we know the sum of all these angles is 180 in any triangle, we can create an equation.

Angle A = 6x + 7

Angle B = 11x-2

Angle C = 90 degrees

A + B + C = 180

Substitute:

6x + 7 + 11x - 2 + 90 = 180

17x + 5 + 90 = 180

17x + 5 = 90

17x = 85

x = 5

Now substitute 5 for x in both acute angles and you will get your answer.

Angle A = 6(5) + 7

Angle A = 30 + 7

Angle A = 37

Angle B = 11(5) - 2

Angle B = 55 - 2

Angle B = 53

Angle A = 37 degrees, and Angle B = 53 degrees.

Hope this helps.
