Find the area of triangle of 7m 9m

Answers

Answer 1

Answer: I think the answer is a=7b*9/2=31.5M

A. f(n) = -7 +4 (n-1)

Step-by-step explanation:

$a_1=-7\,,\ a_2=-3\,,\ a_3=1\,,\ a_4=5\,,\ a_5=9...\implies d=4$

{-3-(-7)=4 and 1-(-3)=4 and 5-1=4 and 9-5=4}

An arithmetic sequence is: $a_n=a_1+(n-1)d$

$a_1=-7\quad and\quad d=4$

$a_n=-7+(n-1)\cdot4$

So:

$f(n)=-7+4(n-1)$

Write this mixed number 6 4/7 as an improper faction in simplest form

Answers

it is 46/7 you could multiply 6x7 and then add 4 = 46/7

46/7. You do 7 times 6 and get 42. 42+4 is 46.
So 46/7 is the answer.

Josiah and his friends are going to the movies. Each ticket costs $10, and popcorn is $5 a bag. There is a $3 service fee for the entire purchase. He has $75. If he buys 4 tickets, what is the maximum number of bags of popcorn he can buy

Answers

Make sure you check this because i do make mistakes.

10 x 4 = 40

75 - 40 = 35

So josiah has 35 dollars to spend for things other than tickets.

35 - 3 = 32 (for the service fee)

So josiah has 32 dollars to spend on popcorn

32/5 = 6.4 but you cant have half a bag of popcorn so

6 bags

Perimeter of the given figure is :---

$(2n) + (2n) +( n + 5) + (n + 5) + (3n + 3) \n = 2n + 2n + n + 5 + n + 5 + 3n + 3 \n = \boxed{9n + 13}✓$

(9n+13) is the right answer

Polygon ABCD will be dilated by a factor of 2 to produce polygon A′B′C′D′. The origin is the center of dilation. Which point will not represent a vertex on polygon A′B′C′D′ ? (-2, -2) (4, 3) (0, 2) (4, -2)

Answers

Since the origin is the center of dilation then the factor of dilation is 2 so just multiply the coordinate of every vertex by 2. So, the vertices will become A'(-2,-2), B'(0, 2), C'(4, 4) ad D'(4,-2). Therefore, letter B is the answer.
