Which expression is NOT equivalent to 40 + 20​

Answer:

12

Step-by-step explanation:

Factors of 30: 1,2,3,5,(6),10,15,30

Factors of 42: 1,2,3,(6),7,14,21,42

30 divided by 6, 42 divided by 6

(5) + (7)= 12

Answer:

The value of a₁₀ is -1352

Step-by-step explanation:

a₂ = -8

a₅ = -512

Now,

a₂ = -8 can be written as

a + d = -8 ...(1) and

a₅ = -512 can be written as

a + 4d = -512 ...(2)

Now, from equation (2) we get,

a + 4d = - 512

a + d + 3d = - 512

(-8) + 3d = - 512 (.°. a + d = -8)

3d = - 512 + 8

3d = - 504

d = - 504 ÷ 3

d = - 168

Now, for the value of a put the value of d = -168 in equation (1)

a + d = -8

a + (-168) = -8

a - 168 = -8

a = 168 - 8

a = 160

Now, For a₁₀

a₁₀ = a + 9d

a₁₀ = 160 + 9(-168)

a₁₀ = 160 - 1512

a₁₀ = -1352

Thus, The value of a₁₀ is -1352

Answer:

Let's simplify step-by-step.

−3(x−4)+3(y−6)

Distribute:

=(−3)(x)+(−3)

(−4)+(3)(y)+(3)(−6)=−3x+12+3y+−18

Combine Like Terms:

=−3x+12+3y+−18=(−3x)+(3y)+( 12+18)=−3x+3y+−6

Answer:

=−3x+3y−6

Answer:

744; 1,206

Step-by-step explanation:

Prism 1:

2(19*13) + 5*12 + 2(5*19)

Multiply all the sides.

494 + 60 + 190 = 744

Prism 2:

2(20*9) + 2(18*20) + 9*14

360 + 720 + 126 = 1,206

Hope this helps (:

Answer:

Common ratio is 3

The three terms are 162, 486, 1458

Step-by-step explanation:

Given: The first 4 terms of a sequence are [tex]2,6,18,54[/tex]

To find:

A. the common ratio

B. the next 3 values in the geometric sequence

Solution:

Geometric sequence is a sequence in which each of the terms is obtained by multiplying the previous term by a fixed number.

A.

[tex]\frac{6}{2}=3\\\\\frac{18}{6}=3\\\\\frac{54}{18}=3[/tex]

So, the common ratio is [tex]3[/tex]

B.

The next three values are as follows:

[tex]54(3)=162\\162(3)=486\\486(3)=1458[/tex]

For example, all equilateral triangles are similar and all squares are similar. If two polygons are similar, we know the lengths of corresponding sides are proportional. In similar polygons, the ratio of one side of a polygon to the corresponding side of the other is called the scale factor.

Answer:

18000

Step-by-step explanation:

1800 x 10 = 18000

Answer:

Step-by-step explanation:

To find the zeros of this polynomial, set the polynomial equal to zero, and then set each of the factors equal to zero separately.  Solve each equation for x:

x  - 1 = 0 yields x = 1.     The x-intercept is (1, 0).

x + 3 = 0 yields x = -3.   The x-intercept is (-3, 0).

2x + 1 = 0 yields x = -1/2   The x-intercept is (-1/2, 0)

Answer:

(- 3, 0), (- 1/2, 0), (1, 0)

Step-by-step explanation:

p(x)=(x-1)(x+3)(2x+1)

Plug p(x) = 0

Therefore,

(x-1)(x+3)(2x+1) = 0

x - 1 = 0 or x + 3 = 0 or 2x + 1 = 0

x = 1 or x = - 3 or x = - 1/2

Hence, (- 3, 0), (- 1/2, 0), (1, 0) are zeroes of the given polynomial

Answer:

[tex]x = 9[/tex]

[tex]y = 17[/tex]

Step-by-step explanation:

This is a cyclic quadralterial so opposite angles are supplementary.

The x variables add up to 180 so

[tex]11x + 8 + 8x + 1 = 180[/tex]

[tex]19x + 9 = 180[/tex]

[tex]19x = 171[/tex]

[tex]x = 9[/tex]

The y variables add up to 180.

[tex]6y - 4 + 5y - 3 = 180[/tex]

[tex]11y - 7 = 180[/tex]

[tex]11y = 187[/tex]

[tex]y = 17[/tex]

Answer:

15,100

Step-by-step explanation:

because 5,200+2,500+8,000+1,800=17,500 which is how much she owes and what she has is 2,400 so 17,500- 2,400= 15,100 so her net worth is 15,100

Answer:

Radius of the cylinder = 1.69 units

Step-by-step explanation:

Volume of a cylinder is given by the expression,

Volume = Area of the circular base × Height of the cylinder

Area of the circular base = πr²

Here, r = Radius of the circular base

Volume of the cylinder = πr²h

By substituting the values given in the question,

72 = π(r)²8

r² = [tex]\frac{9}{\pi }[/tex]

r² = 2.865

r = 1.692

r = 1.69 units

Answer:196

Step-by-step explanation:

Answer:

196

Step-by-step explanation:

Exponential expressions are just a way to write powers in short form. The exponent indicates the number of times the base is used as a factor. So in the case of 32, it can be written as 2 × 2 × 2 × 2 × 2=25, where 2 is the “base” and 5 is the “exponent”. We read this expression as “two to the fifth power”.

Step-by-step explanation:

Answer:

A. 2a+6b

B. a+(a+6b)

D. a + 3b

E. 2a+(5+1)b

Step-by-step explanation:

Given:

2(a + 3b)

Open parenthesis

= (2a + 6b)

A 2a+6b

B. a+(a+6b)

= a + a + 6b

= 2a + 6b

C 2b+3a

Not equivalent

D. a + 3b

2a + 6b

Divide through by 2

= a + 3b

E. 2a+(5+1)b

= 2a + (6)b

= 2a + 6b

F. a2+b5

Not equivalent

Answer:No he is not correct.

Answer:

The explicit formula is;

Tn = 256(1/4)^(n-1)

The 9th term is;

256/65536

Step-by-step explanation:

Mathematically, we have the nth term of a geometric sequence as;

Tn = ar^(n-1)

a is the first term = 256

r is the common ratio = 64/256 = 16/64 = 4/16 = 1/4

So, for the 9th term, we have

T9 = 256(1/4)^(9-1) = 256/65536

The explicit formula is;

Tn = 256(1/4)^(n-1)
