Answer:

P = 40 m

A = 100 m²

Step-by-step explanation:

(10√2)² = 200

200/2 = 100

side length = √100 = 10 m

P = 10 x 4 = 40 m

A = 10 x 10 = 100 m²

1. Distribute or open parenthesis

= 6x-3

15+8= 23

2. Solve

6x-3 = 23

Subtract 3 on both sides

6x= 20

Divide both side by 6

x= 20/6

x= 3.333 or 3 1/3

Answer:

$13.50

Step-by-step explanation:

So excluding tax and tip, let's find the cost of the meal.

$6.70 + $1.95 + $2.35 =  $11.00

Now let's add the 4.5% tax. We do this by adding 4.5% of 11.00 to 11.00

$11.00 + 0.045($11.00) = $11.495 which rounds to 11.50

Now the tip is 2 dollars, so add 2 to 11.50 to get $13.50

Answer: derive function f(x) and you get f'(x) = 4x+ 8

Step-by-step explanation: Derivation gives a function which tells

Is original function increasing or decreasing.

When f'(x) = 0, it means that original function of second degree

Changes its direction. Now you solve 4x+8 = 0 and x=-2.

That's the minimum point in his case.

The completed frequency table is given as follows:

A frequency table is constructed counting the number of observations for each interval in the data-set.

Hence:

Between 85 and 90 there are 4 observations, given as follows:

86, 89, 90, 87.

Between 90 and 95 there are 3 observations, given as follows:

92, 95, 92.

Between 95 and 100 there are 6 observations, given as follows:

97, 98, 100, 97, 96, 99.

Between 100 and 105 there are 4 observations, given as follows:

105, 101, 101, 102.

Between 105 and 110 there are 3 observations, given as follows:

106, 107 and 108.

These numbers of observations were used to construct the frequency table, given at the beginning of the answer.

Answer:

760ft

Step-by-step explanation:

First you find the volume of the rectangle thing :)

so 14 times 19 times 2 = 532ft

than you need to do the triangle so 20 - 14 (for base length) is 6

so 19 times 6 times 2 = 228ft

now you ad them, so 532 + 228 = 760

Answer:

[tex]x^3y^6 + 27z^{42} = (xy^2 + 3z^{14})(x^2y^4 - 3xy^2z^{14} + 9z^{28})[/tex]

Step-by-step explanation:

Given

[tex]x^3y^6 + 27z^{42[/tex]

Required

Factor

Express both terms as a cube

[tex]x^3y^6 + 27z^{42} = (xy^2)^3 + (3z^{14})^3[/tex]

Let

[tex]a =(xy^2)[/tex]

[tex]b = (3z^{14})[/tex]

So:

[tex]x^3y^6 + 27z^{42} = a^3 + b^3[/tex]

Using sum of cubes:

[tex]a^3 + b^3 = (a + b)(a^2 - ab + b^2)[/tex]

So:

[tex]x^3y^6 + 27z^{42} = (a + b)(a^2 - ab + b^2)[/tex]

Substitute in, values of a and b

[tex]x^3y^6 + 27z^{42} = (xy^2 + 3z^{14})((xy^2)^2 - (xy^2)*(3z^{14}) + (3z^{14})^2)[/tex]

[tex]x^3y^6 + 27z^{42} = (xy^2 + 3z^{14})(x^2y^4 - 3xy^2z^{14} + 9z^{28})[/tex]

19.9 + 113.6 = 133.5

180-133.5= 46.5

Answer:

[C] 46.5°

Step-by-step explanation:

Given:

In triangle xyz, angle x measures 19.9° and angle

y measures 113.6°. what is the measure of angle z

Note that:

Triangle = 180 degree

Solution:
Since,

x = 19.9 degree

y = 113.6 degree

then we have:

19.9 + 133.6 + z = 180

133.5 + z = 180

Subtract both sides by 133.5

133.5 - 133.5 = 180 - 133.5

x = 46.5 degree

Hence, the measure of angle z is 46.5

Also means that [C] 46.5 is the correct answer.

Step-by-step explanation:

The nomial number(prefix) is determined by how many terms are in a parentheses. For example, The first one (3z) (9z) has one term bc 3z is one tern and 9z is one term so they are both monomials but b-1 would be a binomial because it has two terms so knowing that should explain my answers
