Answer:

△QPR ≅ △TSU

Step-by-step explanation:Remember, they always look the same, so if △QPR ≅ △STU, it won't work because they are not identical anymore. For example, if you do △ABC ≅ △ABC, △BCA is not the exact same as △CAB. I hope this helps you!

Simora [160]

Answer:

$1+r+r^{2}+r^{3}+.....+r^{n-1} = \frac{1-r^{n}}{1-r}$

Step-by-step explanation:

Taking the succession:

$1+r+r^{2}+r^{3}+.....+r^{n-1}$

You can multiply and divide by 1-r without chaging the result:

$\frac{1-r}{1-r} (1+r+r^{2}+r^{3}+.....+r^{n-1})$

Distributing the upper part of the fraction you have:

$\frac{1}{1-r} (1-r+r-r^{2}+r^{2}-r^{3}+r^{3}-r^{4}+.....+r^{n-1}-r^{n})$

As can be seen all the intermediate members will be canceled by a same member with opposite sign, only $(1-r^{n})$ will be left so:

$1+r+r^{2}+r^{3}+.....+r^{n-1} = \frac{1-r^{n}}{1-r}$

2x + 5= 12 <br> whats x?

nignag [31]

Answer:

x = 7/2 = 3 1/2

Step-by-step explanation:

2x + 5= 12

Subtract 5 from each side

2x + 5-5= 12-5

2x = 7

Divide each side by 2

2x/2 =7/2

x = 7/2

Changing from an improper fraction to a mixed number

2 goes into 7 3 times with 1 left over

x = 3 1/2

(5.3a−0.8)−(1.6−4.7a)=2a−(a−0.3)

sammy [17]

Answer: a = 0.3

Step-by-step explanation:

First, distribute(-1)

5.3a-0.8-1.6+4.7a=2a-(a-0.3)

Then, distribute(-1)

5.3a-0.8-1.6+4.7a=2a-a+0.3

Then, combine like terms

10a-2.4=a+0.3

Then, add(2.4)

10a=a+2.7

Then, subtract(a)

9a=2.7

Then, divide(9)

a = 0.3

Hope it helps <3
