Answer:

C and A

Step-by-step explanation:

Part 1.

The area of a trapezoid is base 1 + base 2 divided by 2 times height.

Base 1 is 38, base 2 is 14, and the height is 16.

38 + 14 = 52, 52 / 2 = 26, and 26 x 16 = 416.

The answer is C, 416.

Part 2.

The area of a kite is diagonal 1 times diagonal 2 divided by 2. The length of diagonal 1 is 12 (on the left) + 12 (on the right) = 24. The length of diagonal 2 is 10 (on the top) + 18 (on the bottom) = 28.

28 x 24 / 2 = 336.

The answer is A, 336

Answer:

336

Step-by-step explanation:

In the figure, there are four triangles

Total Area = sum of four triangles areas

0.5(12*18)*2+0.5(12*10)*2=336

Answer:

Distance = 10.77 unit (Approx.

Step-by-step explanation:

Given:

Coordinate of Jenna's house = (2,4)

Coordinate of Zac's house = (-2,-6)

Find:

Distance

Computation:

Distance = √(X1 - X2)² + (Y1 - Y2)²

Distance = √(2 + 2)² + (4 + 6)²

Distance = √(2 + 2)² + (10)²

Distance = √16 + 100

Distance = √116

Distance = 10.77 unit (Approx.

Answer:

i dont know

Step-by-step explanation:

SA = (5 × 4) + (5 × 12) + (4 × 12)

= 20 + 60 + 48

= 128

Speed per hour = distance / time

Speed = 73 1/3 / 3/2

Speed = 220/3 / 3/2

Speed = 220/3 x 2/3

Speed = 440 /9

Speed = 48 8/9 miles per hour.

Answer:

10π

Step-by-step explanation:

Length for arc = θ/360 × πd

Where,

θ = 180°

d = 20

Length of the given arc = 180/360 × π × 20.

= 10π

Answer:

1600. Because 20/4is 5 so there is 5time doubling so

first time 50 to 100

second time 100 to 200

third 200to400

fourth 400to 800

fifth 800to 1600.

In 20 years the number of Acromantula will be 1600 if the number of Acromantula is doubling in every 4 years.

The unitary method is a technique for solving a problem by first finding the value of a single unit, and then finding the necessary value by multiplying the single unit value.

Given, the number of Acromantula doubles in every 4 years.

Also given that, There are 50 Acromantula in the forest.

In 4 years, the number of Acromantula wil be double of 50 i.e., 100

In 8 years, the number of Acromantula will be double of 100 i.e., 200

In 12 years, the number of Acromantula will be double of 200 i.e., 400

In 16 years, the number of Acromantula will be double of 400 i.e., 800

In 20 years, the number of Acromantula will be double of 800 i.e., 1600

Hence, In 20 years the number of Acromantula will be 1600

Step-by-step explanation:

By Pythagoras' Theorem,

[tex] {c}^{2} = {a}^{2} + {b}^{2} [/tex]

where c is always the largest number.

a and b can be interchangeable between the 2nd largest and the 3rd largest numbers.

Given a = 8, b = 15 and c = 17,

[tex] {a}^{2} + b {}^{2} = {8}^{2} + {15}^{2} \\ = 64 + 225 \\ = 289 \\ \\ {c}^{2} = {17}^{2} \\ = 289[/tex]

Since c^2 = a^2 + b^2 , 8 , 15 and 17 are pythagorean triplets.

Now let's move on to 9, 40 and 41.

[tex] {a}^{2} + {b}^{2} = {9}^{2} + {40}^{2} \\ = 81 + 1600 \\ = 1681 \\ \\ {c}^{2} = {41}^{2} \\ = 1681[/tex]

Since c^2 = a^2 + b^2 , 9 , 40 and 41 are pythagorean triplets.

Last let's move on to 4,7 and 8.

[tex] {a}^{2} + {b}^{2} = {4}^{2} + {7}^{2} \\ = 16 + 49 \\ = 65 \\ \\ {c}^{2} = {8}^{2} \\ = 64 [/tex]

Since a^2+b^2 IS NOT EQUAL to c^2, 4,7 and 8 ARE NOT pythagorean triplets.

Answer:

Step-by-step explanation:

Factoring is taking apart products. It helps immensely if you are familiar with how products are formed. That is, it helps to be familiar with your multiplication tables and the rules of divisibility. It also helps to have  thorough understanding of the distributive property and the forms produced by the multiplication of binomials.

The first step is to look for any factors that are common to all of the terms you are factoring. Next steps include ...

__

1.1.1 4x -x^2

There is only one constant, so no constant factors. The variable x appears in all terms, with a lowest power of 1, so x^1 = x is a factor.

  = x(4 -x) . . . . . . . cannot be factored further

__

1.1.2 x² -8y³ . . . . we assume this is the intended expression. (It helps to use appropriate (and consistent) exponent presentation: x^2 -8y^3, or x² -8y³.

There are no common numerical factors, no common variable factors, and the form is not the difference of squares or cubes. This expression cannot be factored.

__

1.1.3 x² +15x -54

This is a trinomial in a single variable (x), so may be factorable as the product of two binomials. The product of binomial factors will have the form ...

  (x -p)(x +q) = x² +(q-p)x -pq

This means we are looking for two factors of 54 that have a difference of 15. Here is where your familiarity with numerical factoring is helpful.

  54 = 54×1 = 27×2 = 18×3 = 9×6

Differences of the factors are 54-1=53, 25, 15, 3. The factor pair we're looking for is 18×3. Comparing that to the above form, we see that q=18 and p=3, so the factorization is ...

  = (x -3)(x +18)

__

1.1.4 6x²y -10xy +15x -25

There are no numerical or variable factors that are seen in all terms. However, we notice that pairs of terms have common factors. Factoring those out gives ...

  = (2xy)(3x -5) +5(3x -5)

At this point, we notice that (3x -5) is a factor of both of these terms, so we can factor it out. This gives the complete factorization ...

  = (2xy +5)(3x -5)

_____

Additional comment

Many methods are promoted for factoring trinomials. It is helpful to understand that the product of factors looks like ...

  (ax +b)(cx +d) = acx² +(ad+bc)x +bd

That is to say, the product of the x² coefficient and the constant term (ac·bd) will have factors (ad, bc) that have a sum equal to the linear term coefficient. Once you realize this, finding the factorization is not so difficult. You look at the factor pairs of abcd in the same way we looked at factor pairs of -54 in problem 1.1.3 above.

14 seats initially so thats your starting number, the +14 has to be there. He is right in saying +3n because it adds 3 every succeeding row. It would be 3 ×2 if its the second row, so 6 plus 14 equals 20 for example
