Prime numbers cannot be broken down anymore, and are only have factors of it's own number and 1.

67 is your answer, as it can only be factored down to 67 x 1.

hope this helps

The best answer would be D) 67 because the other numbers are not prime.

I think the answer may be D. You can graph the points and draw a line through the points to see what other points are intersected by the line.

In ∆abc, m∠cab = 2x and m∠acb = x + 30. if line segment a b is extended through point b to point d, m∠cbd = 5x − 50. what is t

Allisa [31]

The answer is option "3, 40".

<span>m∠cab = 2x
m∠acb = x + 30
m∠cbd = 5x − 50
Now,
</span>m∠cab + m∠acb = m∠cbd
2x+x+30 = 5x-50
2x+x-5x = -50-30
-2x = -80
x = 40

Please Answer its timed The dimensions of a rectangle are represented by the functions shown. g(x)+3x-4 f(x)=2x-9 Which function

Alenkasestr [34]

Answer:

$\boxed{6x^2-35x+36}$

Step-by-step explanation:

The dimensions of the rectangle are represented by functions:

$g(x)=3x-4 \\f(x)=2x-9$

The area is length × width of a rectangle.

$length \times width$

$(3x-4)(2x-9)$

Expand brackets and solve.

$6x^2-27x-8x+36$

$6x^2-35x+36$

Find the sum of the first 40 terms of a geometric sequence where the first term is 16 and the common ratio is 1.1. 704 7,081.480

Lilit [14]

Step-by-step explanation:

The nth term of a geometric progression can be determined by using the formula:

Tn=arn−1

where: a = first term and r = common ratio

Substitute the given values of first term and common ratio into the formula:

Tn=arn−1

T5=(40)(0.5)5−1

T5=(40)(0.5)4

T5=(40)(0.0625)

T5=2.5
