Step-by-step explanation:
x = £FX/£F= 260+10k/40+k = 7.2
<h3>260 +10k = 288 + 7.2k 2.8 k = 28 k=10 </h3>
Answer:
Option A : 15x² + 62x + 63 is the correct answer.
Step-by-step explanation:
Given measurements of the figure are:
5x + 9 and 3x + 7
We have to find the area. We can find the area by multiplying the two expressions.
Area = (5x+9) * (3x+7)
Area = 5x (3x+7) +9(3x+7)
Area = 15x² + 35x + 27x + 63
Area = 15x² + 62x + 63
Hence,
Option A : 15x² + 62x + 63 is the correct answer.
Answer:
54 miles/hour
Step-by-step explanation:
His rate in miles per hour will be also his speed: to calculate the speed, we just need to divide the total number of miles travelled by the total number of hours, so we will have the average speed in the course:
Speed = 216 miles / 4 hours = 54 miles/hour
So the rate Max travelled is 54 miles per hour.
9 hour is the answer hope it helps
Suppose the integers are n , n+2 , n+4 and n+6.
84=n+(n+2)+(n+4)+(n+6)=4n+12.
Subtract 12 from both ends to get.
72=4n.
Divide both ends by 4 to get.
n=18.
So the integers are: 18 , 20 , 22 , 24.
