Answer:
C
Step-by-step explanation:
Using the pythagorean theorem, we can determine if these are right triangles or not.
equation: sqrt a^2+b^2=c
this means the square root of the two shortest sides squared must equal to the largest side, (the hypotenuese).
Work for C:
Squareroot of 32^2 + 24^2 = 40cm
The answer to the first part is 3 1/2 and the answer to the second question is 2/7
D.
-5(-1) + 2(2) = 5 + 4 = 9
-3 + 10 = 7
That answer was (B)................
In expanded form or decimal form 32/100 is equal to 0.32 or 32% or if simplified the fraction is 8/25
