Answer:

[tex]a^{3}[/tex] + [tex]3a^{2}[/tex] + 5a + 15

Step-by-step explanation:

Using tan(x) = 4/3

X = arctan(4/3)

X = 53.1 degrees

Answer:

Step-by-step explanation:

tan x = 4/3

tan x=1.333333

divide both sides by tan

x=1.33333/tan

x=tan inverse of 1.33333

x=53.130

x=53.13 to the nearest tenth

Answer:

Let x=cost of a case of juice

And y=cost of a case of bottled water

Now we are told that:

6x+y=$135---------------eq1----cases and cost for the math club

4x+2y=$110---------------eq2-----cases and cost for the science club

Multiply eq1 by 2 and we get:

12x+2y=$270-------------------eq1a

4x+2y=$110-----------------------eq2

subtract eq2 from eq1a and we get:

8x=$160 divide both sides by 8

x=$20----------------cost of a case of juice

substitute x=$20 into eq2 and we have:

4*$20+2y=$110 or

$80+2y=$110 subtract $80 from both sides

$80-$80+2y=$110-$80 collect like terms

2y=$30 divide both sides by 2

y=$15----------------------------cost of a case of bottled water

CK

6*20+1*15=135

120+15=135

135=135

also

4*20+2*15=110

80+30=110

110=110

Answer:

Step-by-step explanation:

x² + 6x = 8

Coefficient of the x term: 6

Divide it in half: 3

Square it: 3²

Add 3² to both sides of the equation to complete the square and keep the equation balanced:

x² + 6x + 3² = 8 + 3²

(x+3)² = 17

(- 4 * 3 * 2)*2 = - 48

Answer: Option 2

Step-by-step explanation: its option2

Answer:

the first four terms are 0,0,2,6

Step-by-step explanation:

The computation of the first four terms of the sequence is shown below:

Given that

f(n) = (n - 1) (n -2)

= n^2 - 2n - n + 2

= n^2 - 3n + 2

Now the first four terms are

f(1) = 1^2 - 3(1) + 2

= 1 - 3 + 2

= 0

f(2) = 2^2 - 3(2) + 2

= 4 -6 + 2

= 0

f(3) = 3^2 - 3(3) + 2

= 9 - 9 + 2

= 2

f(4) = 4^2 - 3(4) + 2

= 16 - 12 + 2

= 18 - 12

= 6

So, the first four terms are 0,0,2,6

Answer:

x < 3

(*￣3￣)╭

Answer:

The answer is x < 3.

Step-by-step explanation:

1) Simplify 3x - 3 - 6 to 3x - 9.

[tex]0 > 3x - 9[/tex]

2) Add 9 to both sides.

[tex]9 > 3x[/tex]

3) Divide both sides by 3.

[tex] \frac{9}{3} > x[/tex]

4) Simplify 9/3 to 3.

[tex]3 > x[/tex]

5) Switch sides .

[tex]x < 3[/tex]

Therefor, the answer is x < 3.

Answer: T(x) = 18x + 65

Step-by-step explanation:

T(x) = A(x) + B(x)

T(x) = 10x + 50 + 8x + 15             [Plug in the number for A(x) and B(x)]

T(x) = 10x + 8x+ 50 + 15

T(x) = 18x + 65

Answer:

42

Step-by-step explanation:

the ratio 2:4 can be reduced to 1:2,

where the number of girls corresponds to the 1 and the number of boys corresponds to the 2.

If there are 14 girls, then there must be 28 boys (14 x 2 = 28).

Now to get the total number we need to add the total number of boys and girls together.

So 14 + 28 = 42

Hope it helps :)

Answer:

32

Step-by-step explanation:

14 + 28 = 32

2 x 7 = 14

4 x 7 = 28

Answer:

ECB

Step-by-step explanation:

I noticed they looked exactly the same.

Answer:

It should be ΔABD, ΔECD, and ΔECD

Step-by-step explanation:

Since ΔABE is a right triangle, one angle must be 90° with a square to signify it.

Answer:

exactly one solution

Step-by-step explanation:

Solving the equation,

15(30x - 5) = 7 - 2(3+x) - 4x

450x - 75 = 7 - 6 - 2x - 4x

450x - 75 = 1 -6x

456x = 76

x = 76/ 456

x = 1/6

Since the equation has a single value = 1/6 that is true for the equation, it has one solution.

D.f(n) = 3n

Step-by-step explanation:

The function rule for this given situation is shown below;

Given that

The length of the field in feet would be f(n) of the length n in yards

Now as we know that

1 yard = 3 inches

So

f(n) = 3n

Hence, the option d is correct
