Answer:
Step-by-step explanation:
To verify, a number needs to be substituted for x in both expressions. Use order of operations to simplify and find the value. The value needs to be the same for both expressions to prove
Answer:
The area of the enlarged triangle is
times the original area
Step-by-step explanation:
we know that
The scale factor is equal to divide the measurement of the length side of the enlarged triangle by the the measurement of the length of the corresponding side of the original triangle
In his problem
Let
x------> the length side of the original triangle
so
2x-----> is the length of the corresponding side of the enlarged triangle

-------> that means is increasing
The scale factor squared is equal to the ratio of the area of the enlarged triangle divided by the area of the original triangle
so
Let
m-------> the area of the enlarged triangle
n------> the area of the original triangle
r-------> scale factor

we have

substitute


therefore
The area of the enlarged triangle is
times the original area
<span>In order to calculate how long it will take Jamie to finish painting the fence, you should divide the length of the fence by the rate at which Jamie paints. Thus, if the fence is 119.5 yards long and Jamie paints on average 4.78 yards per hour, we divide 119.5 by 4.78 and get the answer - 25 hours. We can double check our work by multiplying Jamie's painting rate by the time, so if Jamie paints 4.78 yards per hour for 25 hours, he will paint all 119.5 yards.</span>
