Answer:

6p + 9 + 12p

18p + 9

Step-by-step explanation:

3(2p + 3 + 4p)

Multiply all the numbers by the outside number. ex: 3(2p + 9). Multiply 3 x 2 which is 6. then you multiply 3 x 9 which is 27. So the answer would be 6p + 28.

Pt 2. 3 times 2 is 6 so you get 6p. Then you multiply 3 times 3 which is 9. then 3 times 4p which is 6 p.

pt 3. combine the like terms. 6p + 12p equals 18p.

so the answer would be 18p + 9.

(I tried my best. please dont judge.

Answer:

The lateral surface is increased by a factor of 2.

Step-by-step explanation:

Since each side of the base was doubled in length, but the height of the prism remains the same, all sides double in area.

Therefore the total new lateral area is double what it was.

The lateral surface is increased by a factor of 2.

Answer: 68 degrees

Step-by-step explanation:

Let the measure of the angle be x.

The supplement of the angle is 180 - x as supplementary angles add up to 180 degrees.

The complement of the angle is 90 - x as complementary angles add up to 90 degrees.

We can set up an equation.

180 - x = 46 + 3*(90-x)

180 - x = 46 + 270 - 3x

Combine like terms:

2x = 136

Divide both sides by 2:

x = 68

What are supplementary and complementary angles?

The supplement of an angle (180 - x) is [=] 46 more than 3 times the complement (90-x):

180 - x = 3 (90 - x) +46

Now, solve for x:

180 - x = 3 (90 - x) +46

180 - x = 270 - 3x +46

180 - x = 316 -3x

-x = 136 -3x

2x = 136

x = 68

The angle is 68°

It would not be any of those answers. it would be 106 :) Its negative numbers divided

The value of expression is,

⇒ - 27 / 79

Division method is used to distributing a group of things into equal parts. Division is just opposite of multiplications. For example, dividing 20 by 2 means splitting 20 into 2 equal groups of 10.

Given that;

The expression is,

⇒ 27 ÷ (- 34 - 45)

Now, We can simplify as;

⇒ 27 ÷ (- 34 - 45)

⇒ 27 ÷ - 79

⇒ - 27 / 79

Thus, After simplification, we get;

⇒ - 27 / 79

B = (4, 0)

Step-by-step explanation:

We are told that  [tex]l_2[/tex]  intersects the x-axis at B.

To determine where  [tex]l_2[/tex]  intersects the x-axis, set y to zero in the [tex]l_2[/tex]  equation and solve for x:

[tex]\implies 0+x=4[/tex]

[tex]\implies x=4[/tex]

Therefore, B is (4, 0)

Answer:

(4,0)

Step-by-step explanation:

coordinate B lies on the equation y + x = 4

y = 0 and x is unknown, so putting this in the equation:

y + x = 4

0 + x = 4

x = 4

The greatest value in the range of f(x) is 8.

The domain of a function is defined as the set of all the possible input values that are valid for the given function.

The range of a function is defined as the set of all the possible output values that are valid for the given function.

WE are given that the domain for f(x) = 3x + 2 is -3 ≤ x ≤ 2.

We just need to replace x with the highest value;

f(2) = 3(2) + 2

f(2) = 8

Using the combination formula, it is found that there are 129 different combinations.

[tex]C_{n,x}[/tex] is the number of different combinations of x objects from a set of n elements, given by:

[tex]C_{n,x} = \frac{n!}{x!(n-x)!}[/tex]

In this problem, combinations of 1, 2 or 3 pieces from a set of 9 are taken, hence:

[tex]C_{9,1} = \frac{9!}{1!8!} = 9[/tex]

[tex]C_{9,2} = \frac{9!}{2!7!} = 36[/tex]

[tex]C_{9,3} = \frac{9!}{3!6!} = 84[/tex]

Then, the total is of:
