Hi!
So obviously we have to divide each side by -5. It's pretty simple! Let me show you...
-125 ≥ -135
-125/-5 ≥ -135/-5
dividing 2 negative numbers make a positive
25 ≥ 27
Now that the expression has changed, we have to flip the inequality sign.
25 ≤ 27
^the answer
Hope this helps! :)
Ask your teacher for help you didn't give us a lot of details at all . Sorry I could help you .
Step-by-step explanation:
1. 3(p-q)
2. 4(2m+3n+4r)
3. 2x(2x-3y)
Answer:
Step-by-step explanation:
12). By applying Pythagoras theorem in the given right triangle,
Hypotenuse² = (Leg 1)² + (Leg 2)²
x² = 7² + 7²
x² = 2(7)²
x = 
x = 
13). By sine rule,
sin(60)° = 

y = 
y = 18
By cosine rule,
cos(60)° = 

x = 
x = 
14). By applying Pythagoras theorem in the given right triangle,
12² = x² + x²
144 = 2x²
72 = x²
x = √72
x = 6√2
