Answer:
b
Step-by-step explanation:
so 17 squared minus 8 squared is 225. the square root of 225 is 15
Similar triangles so AC:BC=AE:DE
15+6=21 = AE
15:12.5=21:?
to get from 15 to 12.5 you divide by 15 and times by 12.5 so do this the to the other side
21/15=1.4
1.4 x 12.5=17.5
So DE=17.5
Answer: 1 over 3
Step-by-step explanation:
81 divided by 27 is 3
Answer:
(A) 49
Explanation:
Most of the equation is just explaining what length and width is.
Area = L (length) · W (Width)
Option One:
Length: 9
Width: 5
9 · 5 = 45
There is no option for 45 so we need to check option two.
Option Two:
Length: 7
Width: 7
7 · 7 = 49
There is an option for 49, so that is our answer.
Basically, they are just explaining that Area = L · W, and to check both options to see if there is an answer.
