Answer B is correct. Sum is the answer to an addition problem, so sum of 8 and 2 would be 8+2.
Answer:
z = 4.5
Step-by-step explanation:
∠B = ∠B ∠BAD = 90° - ∠B = ∠C
ΔBAD ~ ΔBCA
AB / z = BD / AB
z = AB * AB / BD = 3*3 / 2 = 4.5
Answer:
$11543.63
Step-by-step explanation:
<u>Plug information into A=P(1+r/n)^nt</u>
13000 = P(1+(.04/2))^(2*3)
13000 = P(1.02)^6
<u>Isolate P</u>
13000/(1.02^6) = P
P = $11543.63
64-25=39
All the square numbers are 1,4,9,16,25,36,49,64,81,100
Answer:
Simply: It makes sure you get the correct answer
Step-by-step explanation:
Using order of operations (pemdas) ensures you do the correct operations in the correct order. If not, then everyone could get loads of different answers for the same question. It provides order in the math world.
