Answer:

First then second answer below

Step-by-step explanation:

-x+y 4

-1/-1=1      x=1    y=1  

y/1=1/1+4/1

y=1x+4

-x+7y 21

-1/-1=1

7y/7=1/7+21/7

y=1/7x+3

Write (9 +6/) - (1 + 3/) as a complex number in standard form.
kirza4 [7]

I'm assuming the given problem is (9+6i) - (1+3i)

If that assumption is true, then this is what the steps look like

(9+6i) - (1+3i)

9+6i - 1-3i

(9-1)+(6i-3i)

(9-1)+(6-3)i

8+3i

<h3>Answer: 8+3i</h3>

Which of the following sets of lengths can Sean use to make a right triangle?
Aleks [24]

Answer:

{8 cm, 15 cm, 17 cm}

Step-by-step explanation:

we know that

The length sides of a right triangle must satisfy the Pythagoras Theorem

so

c^2=a^2+b^2

where

c is the greater side (the hypotenuse)

a and b are the legs (perpendicular sides)

<u><em>Verify each case</em></u>

case 1) we have

{5 cm, 15 cm, 18 cm}

substitute in the formula

18^2=5^2+15^2

324=250 ----> is not true

therefore

Sean cannot make a right triangle with this set of lengths

case 2) we have

{6 cm, 12 cm, 16 cm}

substitute in the formula

16^2=8^2+12^2

256=208 ----> is not true

therefore

Sean cannot make a right triangle with this set of lengths

case 3) we have

{5 cm, 13 cm, 15 cm}

substitute in the formula

15^2=5^2+13^2

225=194 ----> is not true

therefore

Sean cannot make a right triangle with this set of lengths

case 4) we have

{8 cm, 15 cm, 17 cm}

substitute in the formula

17^2=8^2+15^2

289=289 ----> is true

therefore

Sean can make a right triangle with this set of lengths

(2x-7)^2 subtracted from 2
weqwewe [10]

Write out the expression 2 - (2x-7)^2.  That's it.

But if you want to go further and remove the parentheses, first expand (2x-7)^2:   (2x-7)^2 = 4x^2 - 28x + 49,

and then subtract this result from 2:

2 - (4x^2 - 28x + 49) (It's important to use parentheses here)

Now, following the distributive property of multiplication, remove the parentheses:

2 - 4x^2 + 28x - 49

Combining the constants, we get the final answer:  - 4x^2 + 28x - 47
