Answer:
6-
Step-by-step explanation:
Your answer should be written in paragraph/essay format.
Any sources used should be cited at the bottom of your paper.
All answers should show you have learned something from Unit 9. Material from other units will not be graded for this assignment.
If you are stuck, you can think about the following topics: textile mills, interchangeable parts, the Lowell System, unions, labor reform, steamboats, railroads, coal, the telegraph, and/or new inventions.
Answer:
Yes; the corresponding sides are proportional
Step-by-step explanation:
If two figures are similar, the lengths of their sides are proportional. This means if we set up a proportion with the sides we are given and cross-multiply, we get a true statement at the end of it.
Using the similarity statement ABCD~EFGH, we will compare AB to EF and BC to FG:
5/3 = 25/15
Cross multiply:
5(15) = 3(25)
75 = 75
We got a true statement, so the sides are proportional.
Answer:
first method
<u>2</u><u>2</u>=<u>5</u>
7. x
we cross multiply to get
<u>2</u><u>2</u><u>x</u>= <u>5</u><u>×</u><u>7</u>
22. 22.
x= <u>3</u><u>5</u>
22
=1.59
second method
<u>2</u><u>2</u>=<u>5</u>
7. x
we multiply the denominators to get 7x
then we multiply each term by 7x
7x×<u>2</u><u>2</u> = <u>5</u>×7x
7. x
here the 7 and 7 will cancel out and the x and x will cancel out to get
<u>2</u><u>2</u><u>x</u>= <u>3</u><u>5</u>
22. 22
= 1.59
3a to the power of 2 plus 5a minus 2
