Plug in the numbers wherever these letter are. Ex: 10x+5y. You would do 10x12=120 and 5x20=100. Add these two numbers to get 220. Hope this helps:)
Exg, so if you wanted to know, how many times 2 goes into 4 then you would do 4/2 or 2 so if you wanted to know how many times x goes into y then you would do y/x and get the answer so
3.15=x 2=y
how many times does 3.15 go into 2 the answer is 2/(3.15)=200/315=40/63= 0.63492063492063
so the answer is 40/63 times or 0.63492063492063 times
You can divide this image into 2 different shapes and there are multiple ways to do this. I drew a line straight down from the side that has a length of 6 to divide the image into 2 rectangles
I now have a rectangle that has sides of 7 and 10 and a rectangle that has sides of 4 and 8
A=L*W so A=7*10 which is 70
A=L*W so A=4*8 which is 32
add these areas together to get 102 so "C" is the correct answer
None of your answers are correct
all you have to do it look at what place the value underlined
for example, find value of 5 in 517,849
the 5 is in the 100 thousands place this means that the value is 500,000
225 x 64 = 14,400
sqrt of 14,400 = 120
x=120
