To Find:
x = ?
Solution:
Step 1: x2 + 4x = 6
Step 2: x2 + 4x + 4 = 6 + 4
Step 3: (x + 2)2 = 10

Answer:
85m
Step-by-step explanation:
Perimeter of a rectangle = 2(l+b)
b=72m, l=?
perimeter =314m
314=2(l+72)
314/2= l+72
157=l+72
l=157-72
l=85m
Answer:
Divide 250 by 9.4 to get 26.6
Step-by-step explanation:
To calculate her unit rate, 1 minute, we must divide the distance travelled over 9.4 minutes by 9.4 to see how far she travelled in 1 minute.
First you would put both numbers into improper fractions.
3 1/3 = 10/3 and 2 1/4 = 9/4
Multiply 10/3 * 9/4
10*9 = 90 and 3 * 4 =12
So 90/12 is your fraction. Reduce it, 7 6/12
7 6/12 = 7 1/2
So your answer is 7 1/2
