The following steps are used to rewrite the polynomial expression (x+4y+z)(x-7y).
Step 1: x(x-7y)+z(x-7y)
Step 2: x^2-7xy+4yx-28y^2+zx-7zy
Step 3: x^2-7xy+4xy-28y^2+xz-7yz
Step 4: x^2-3xy-28y^2+xz-7yz
Identify the property used in each of the steps:
Step 1:
Step 2:
Step 3:
Use Distributive, Commutative, Associative

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.

i need more info. are you looked to see there mph? how much they deliver? how far they go?

step-by-step explanation:

11.2

step-by-step explanation:

when doing tangent the tangent of the angle is equal to the opposite side from the angle over the adjacent side to the angle.

tan43 = x / 12

move 12 over by multiplying each side by 12

12tan43 = x

x = about 11.2
