Step-by-step explanation:
do 21×3.14= 65.94
then divide by 2 since its a semicircle
equals: 32.97
than find perimeter altogether
21+28+28+32.97= 109.97ft
X - 5 = 10
+5 = +5 = 15
x = 15
The bottom one is correct.
Answer:
Q = 3.2
Step-by-step explanation:
So basically you would first re-order the equation. 6.4 + Q = 9.6
Then after that you will move all the terms containing Q to the left and the rest of them on the right. After that you will -6.4 to both sides of the equation. Which will look like this.
6.4 + (-6.4) + Q = 9.6 + (-6.4)
Then you will combine the like terms.
6.4 + (-6.4) = 0.0
0.0 + Q = 9.6 + (-6.4)
<u>Q = 3.2</u>
