Answer:

C. 390 cm²

Step-by-step explanation:

Area of Rectangle: l•w

Area of Triangle: 1/2bh

Rectangle:

20 cm • 15 cm = 300 cm²

Triangle:

1/2(12)(15)

1/2(180)

90 cm²

Entire Shape:

300 cm² + 90 cm² = 390 cm²

In general, a variable to any even power is a perfect square.

So for example, x² is a perfect square and so is y¹⁴.

A common made by students is not in factoring the difference of two squares, but just failing to recognise that the difference of two squares exist.

Answer:x+42+3x = 90

Combine like terms:

3x+x = 4x

42+4x = 90

Subtract 42 to both sides

90-42 = 48

Divide 4 by 48

48/4 = 12

The fraction of 33 kg as a fraction of 4 tonnes is 33/4000.

The same property is expressed using a unit conversion, but in a different unit of measurement. For instance, time can be expressed in minutes rather than hours, and distance can be expressed in kilometers, feet, or any other length unit instead of miles.

For example, inches, centimeters, and miles are all measures of distance.

Given:

Amount= 33 Kg

We have to convert Kg into Tones

We know, 1 tonne= 1000 Kg

So,4 tonee = 4 x 1000

                = 4000 Kg

Thus, 33 kg as a fraction of 4 tonnes.

= 33/4000

Answer:

54

Step-by-step explanation:

deltamath gave me the answer

The length of w is 54 cm.

One of the six mathematical functions used to express the side ratios of right triangles, the trigonometric function includes the sine (sin), cosine (cos), tangent (tan), cotangent (cot), secant (sec), and cosecant (csc). The figure shows these six trigonometric functions in respect to a right triangle. Surveying, engineering, and navigation issues where one of a right triangle's acute angles and the length of a side are known but the lengths of the other sides need to be determined can be solved with ease using trigonometry.

As per the given data:

x = 41 cm

v = 17 cm

∠W = 134°

To find the length of w:

From the cosine law:  [tex]cos(W) = \frac{x^2 + v^2 - w^2}{2xv}[/tex]

[tex]w = \sqrt{x^2 + v^2 - 2xvcos(W)}\\w = \sqrt{(41)^2 + (17)^2 - 2(41)(17)cos(W)}\\w = \sqrt{1681 + 289 + 968.35} = \sqrt{2938.35}\\w = 54 \:cm[/tex]

Hence, the length of w is 54 cm.

To solve the quadratic equation (x - 18)^2 = 1, we can take the square root of both sides and consider the positive and negative roots. Here's how we can proceed:

Taking the square root of both sides gives us:

x - 18 = ±√1

Simplifying the square root of 1, we have:

x - 18 = ±1

Now, let's solve for x by considering both the positive and negative cases:

Case 1: x - 18 = 1

Adding 18 to both sides:

x = 1 + 18

x = 19

Case 2: x - 18 = -1

Adding 18 to both sides:

x = -1 + 18

x = 17

Leading to our final correct answer is:

A. x = 19 and x = 17

According to this, the answer is that the average cost per vet visit was $19.25.

Answer: C 3a^4

Step-by-step explanation:

I just took the test

The multiplication operation to multiply the equation (4a^3 - 2a + 3a^2 + 1) and (3 - 2a + a^2) with vertical method is done and the value of D obtained is 3a⁴.

The vertical method to multiply is one of the simple method to perform multiplication operation.

In this method, the two terms which need to be multiply is kept one below the other and each element of first is multiplied with the other term.

The equations given in the problem are, (4a^3 - 2a + 3a^2 + 1) (4a3−2a+3a2+1) and (3 - 2a + a^2). (3−2a+a2). Arrange them and write in vertical manner to multiply.

Answer:

At least 24 (if started around 19) or 23 (if started internship around 18)

[ results are only if the boars are dead and the ship's capacity is closest to the TEU ]

Step-by-step explanation:

4x and 6x sit on a straight line therefore must equal to 180°

4x+6x = 180° (∠'s on str. line)

10x = 180

x= 180/10

x= 18

Then we need to find ∠UYV

∠UYV = 4x

=4(18)

=72°

So ∠UYV = 72°
