If you get this right I'll make you the brainiest
39+19*989/2*3+55

28280.5?

Step-by-step explanation:  was this right

using order of operations you will want to simplify your equation using PEMDAS

39 + 19 * 989/2 * 3 + 55

39 + 9395.5 * 3 + 55

39 + 28186.5 + 55

28225.5 + 55 = 28280.5

Step-by-step explanation:

Hope this is right! Have a nice day

edit: you said its wrong so is this right ? if so u did not use order of operations correctly 57968.5

its adding 5.5 each time

step-by-step explanation:

the answer is:

the lateral area is equal to

to find the lateral area of the square pyramid, first we need to find the perimeter of the base, and then, find the lateral area using the following formulas:

where,

s, is the base length

slant height, is the height of a the side of the pyramid

we are given:

now, calculating the perimeter of the base, we have:

then, calculating the lateral area:

hence, we have that the lateral area is equal to

have a nice day!
