The formula for triangle area is b•h/ 1/2. so you would do 12•5=60. then divide that by 2 to get 30
to find the first places you have to look at the ones tens and hundreds so the first place is in the ones place
I hope this helps
Step-by-step explanation:
First, apply the distributive property to the left side of the equation. Multiply each of the two numbers inside the parentheses by 12 and then combine those products. Next, solve as you would solve any two-step equation. To isolate \begin{align*}12x\end{align*} on the left side of the equation, add 24 from both sides.
Step-by-step explanation:
12 is rounded to 10
22 is rounded to 20
20×10= 200
