Which method of solving for the variable could be used instead of cross multiplication? distributing x + 3 and then 3x + 5 to both sides of the equation distributing x – 3 and then 3x – 5 to both sides of the equation using the multiplication property of equality to multiply both sides of the equation by 10 using the multiplication property of equality to multiply both sides of the equation by One-tenth

trapezoid

step-by-step explanation:

first i plotted all my points on a grid graph

i made sure all of them were in the correct quadrant

then i saw it was a trapezoid or a quadrilateral

, and

for

step-by-step explanation:

we can analyze the pattern at which the terms increase. let us denote , , , so that we can call

note the following:

the pattern: to get the next term value, we just add the next term number (e.g. 1st, 2nd, to the previous term value (term values are the given numbers in the question, 1, 3, 6, 10, 15,

from , to get to , we add

from , to get to , we add

etc.

we need to form a recursive formula, a formula that has the next term as a function of the previous term. so a possible recursive formula can be

, and for

what i would say the best answer is a. 40.5
