Ganezh [65]1 year ago

Answer:

a) 10x² - 3x - 18

b) 14x + 6

Step-by-step explanation:

<u>Given:</u>

length = 5x + 6

width = 2x - 3

Tables usually have rectangular shape.

a) Area of the table

<u>Area of a rectangle</u>

A = length × width

Insert values into formula.

A = length × width

A = (5x + 6) × (2x - 3)

A = 10x² - 15x + 12x - 18

A = 10x² - 3x - 18

b) Perimeter of the table

<u>Perimeter of a rectangle</u>

P = 2 × length + 2 × width

P = 2 × length + 2 × width

P = 2(5x + 6) + 2(2x - 3)

P = 10x + 12 + 4x - 6

P = 14x + 6

Solve 1/p+1/s=1 for p
jekas [21]

Answer:

Step-by-step explanation:

Multiply through by the L. C. M which is PS.

1/p*ps+1/s*ps=1*ps

P+p=ps

2p=ps

Divide both sides by 2

2p/2=ps/2

P=ps/2

Here's the question: You have an electrical circuit with various components, all of which are in series. The current (I) through
vredina [299]

Answer:Magnitude of voltage is 41.9963 volts


Step-by-step explanation:

Given that current I =5.772-5.323i mA

          and impedance, Z=3.342+4.176i kilo ohms

Then voltage in the circuit = IZ

                                            =(5.772-5.323i)X10^{-3}X(3.342+4.176i)X10^{3}

                                      V=(5.772-5.323i)X(3.342+4.176i)

                                      V=19.290024+24.103872i-17.789466i-23..5148848i^{2}

                                     V=41.518892+6.314406i

Magnitude of V = \sqrt{41.518892^{2} +6.314406^{2} }=\sqrt{1763.6901}=41.9963volts

A rectangle has a height of a² + 3 and a width of a² + 2a + 5.
valentina_108 [34]

Answer:

Area =  a^4+2a^3+8a^2+6a+15

Step-by-step explanation:

The area of a rectangle is given by:

Area = Height * Width

The expressions for height and width are given. We just need to multiply and add like terms (if applicable) to find the expression for the area of the rectangle.

Remember to use distributive property:

(a+b)(x+y) = ax + ay + bx + by

Thus, we have:

(a^2+3)(a^2+2a+5)\\=(a^2)(a^2)+(a^2)(2a)+(a^2)(5)+3a^2+6a+15\\=a^4+2a^3+5a^2+3a^2+6a+15\\=a^4+2a^3+8a^2+6a+15

THis is the expression for area.
