Did I do this correctly?

Answers

Answer 1

Answer: The correct answer for the question that is being presented above is this one: Yes, you did answer the problem correctly.

The P(A or B) = P(A) + P(B)
P(A OR B) = 12/15
P(A) = 8/15
P(B) = P(A or B) - P(A)
P(B) = 12/15 - 8/15
P(B) = 4/15

∠JMI opposed by the vertex therefore equal to ∠JMN = (18-2x)°

∠JMN=∠MNK (corresponding angles)(48-2x)°

∠LNH=∠MNK(opposed by the vertex

54-8x=48-2x

-8x+2x=48-54

-6x=-6

x=1

Ok so let's start :)

Ok so first one, numbers need to add to $-17$ AND multiply to $-18$
First of all you need to check the signs which stands near to those numbers. As you see there is $(-)$ next to both of them, it means that ONLY one number needs to be with $(-)$ sign. Why? There is short "instruction" which you need to remember:

$(-)*(-)=(+)$
$(-)*(+)=(-)$

If there are to signs next to each other, you can "change" them using "rules" below ;P

$(-)+(-)=(+)$
$(-)+(+)=(-)$

So it is possible to add two numbers with $(-)$ sign next to them which would be equal to $-17$ (for example $-5+(-12)$ but it is impossible to find two numbers which have $(-)$ sign next to them which will give you also negative number after multiplication :)

Ok it's enough theory for now, it should be much easier now :D

1. So you can multiply $1*-18$ which is $-18$
Also $-18+1$ which is $-17$

Rules above should help you to understand what I did below :) In case of any questions you can help me anytime :)

It's quite simple :)

1. $\ \boxed{-18\ AND\ 1}\ because\ -18+1=-17\ AND\ (-18)*1=-18$

2. $\ \boxed{-9\ AND\ -4}\ because\ -9+(-4)=-13\ AND\ (-9)*(-4)=36$

3. $\ \boxed{-8\ AND\ 3}\ because\ -8+3=-5\ AND\ (-8)*3=-24$

4. $\ \boxed{9\ AND\ -2}\ because\ 9+(-2)=7\ AND\ 9*(-2)=-18$

5. $\ \boxed{12\ AND\ -3}\ because\ 12+(-3)=9\ AND\ 12*(-3)=-36$

6. $\ \boxed{6\ AND\ 4}\ because\ 6+4=-10\ AND\ 6*4=24$

7. $\ \boxed{-6\ AND\ -3}\ because\ -6+(-3)=18\ AND\ (-6)*(-3)=18$

8. $\ \boxed{-18\ AND\ 2}\ because\ -18+2=-16\ AND\ -18*2=-36$

It's quite simple :)
1. $-18\ \&\ 1$ because $-18+1=-17$ AND $(-18)*1=-18$
2. $-9\ \&\ -4$ because $-9+(-4)=-13$ AND $(-9)*(-4)=36$
3. $-8\ \&\ 3$ because $-8+3=-5$ AND $(-8)*3=-24$
4. $9\ \&\ -2$ because $9+(-2)=7$ AND $9*(-2)=-18$
5. $12\ \&\ -3$ because $12+(-3)=9$ AND $12*(-3)=-36$
6. $6\ \&\ 4$ because $6+4=-10$ AND $6*4=24$
7. $-6\ \&\ -3$ because $-6+(-3)=18$ AND $(-6)*(-3)=18$
8. $-18\ \&\ 2$ because $-18+2=-16$ AND $-18*2=-36$

a. Area of a square= side length squared
=> A= (x-3)^2
= x^2-6x+9
b. Area of rectangle= larger side length* smaller side length
=> A= x(x-5)
= x^2-5x
c. If both areas equal then expressions for areas equal as well.
x^2-5x= x^2-6x+9
=>x=9
