Mr. Lombardo is trying to figure out how many cupcakes to make for his birthday. He knows that he wants to make 2 cupcakes for each person he invites.

Write an equation to represent the total number of cupcakes he must make.

i only know the sequence of arithmetic it adds the first is 5+4 then it goes up as it adds to then it is 9+5 then 14+6 then to 20+7 and so on. 5,9,14,20,27,35.

step-by-step explanation:

step-by-step explanation:

this can be solved first with pythagorean theorem, which tells us to square both legs of the triangle and sum it. this will be equal to the square of the hypotenuse.

the hypotenuse is the side "opposite" the 90 degree angle, which is x.

so we can write using pythagorean theorem,

simplifying:

to further simplify this radical, we need to use the property  

thus

perimeter of the base times height

step-by-step explanation:

the answer is that it is true
