What is 5x times (3x2 - 5)?
3x2 + 5x -5
A
B 15x2-5
с
15x3 - 5
15x3 - 25x

15x3-25x

Step-by-step explanation:

5x(3x2 -5)

step1: distribute 5x to both sides

Step 2: 3x2 would change into 15x3 (because you're multiplying by 5x)

Step3: -5 would turn into -25x (because you are multiplying by 5x also)

Step4: put both answers together and your end product would be (15x3 - 25x)

arithmetic sequence

step-by-step explanation:

given that a sequence has terms as

19, 15, 11,

this is represented on a graph

the pattern indicates that the sequence is an arithmetic sequence with i term

a=19 and common difference d =-4

any general term

thus the sequence is reduced by 4 for each successive term starting from 1 and nth term is

24-5n.

first negative term would start after 5th term

5th term =24-25< 0

from 5th term onwards the sequence would be negative.

so a parallelogram is just like a square base times height. multiply 40 and 39 to get 1560 inches.

a triangle is base times height divided by two. so multiply 7.9 and 5 and then divide it by 2 to get 19.75inches.

the kite can be split into two separate triangles and added together to get the total area. 30 x 4 /2 which equals 60. make sure to double it for the two triangles making 120.
