Explain how you could find 8times45 by using distributive property and

Express 45 = 40+5 then

8 times 45 can be written

8(40+5) = 320+40 = 360

step by step explanation: when u removing the parentheses and combined them that would be : x+3y-x-y=2y

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!
