Answer:
1
Step-by-step explanation:
1^2=1
Answer:
c) 3
Step-by-step explanation:
22=2x2 +4
22-4
18=2x2
18/2
9=x2
x=3
X=8.5
190-5=185
185/-5=-37
-37-3=-34
34/4=8.5
This is a proportion, she is walking 3.3 every hour. She walked for 5.4 hours. And we don't know how far she walked so its x/.54. Then you cross multiply which gives you 3.9×.54=x. We multiply those decimals and we get 1.782.
Answer:
±6
Step-by-step explanation:
Given the mathematical expression;
√36 < √42 < √49
But, √36 = 6 * 6 = 6²
√49 = 7 * 7 = 7²
Simplifying further, we would substitute the new values respectively;
±[6] < √42 < ±[7]
Therefore, evaluating √36 is equal to ±6.
