Step-by-Step Thingy:</h3>
Adding a negative number is basically just subtracting a number, using that...
-4+(-2) ---> -4-2
Now all that's needed is to minus 2 from -4.
-4-2 ---> -6
Hope that helps, :)
Answer:
x=12
Step-by-step explanation:
63+8x-17+3x+2=180
48+11x=180
11x=132
132/11=12
Answer: 16%
Step-by-step explanation:
The total number of species of shark evaluated = 465
Number of sharks currently endangered or threatened = 74
Percent of sharks endangered = (Number of sharks / Total number of sharks evaluated) x 100%
= (74/465) x 100%
= 0.1591 x 100%
= 15.91%
Round 15.91% to the nearest whole percent = 16%
Thus, 16% of the total sharks evaluated are currently endangered or threatened.
we can use formula
![a^3-b^3=(a-b)(a^2+ab+b^2)](https://tex.z-dn.net/?f=%20a%5E3-b%5E3%3D%28a-b%29%28a%5E2%2Bab%2Bb%5E2%29%20)
we can compare
we get
a=x
b=2
now, we can plug that in formula
and we get
![x^3-2^3=(x-2)(x^2+2x+2^2)](https://tex.z-dn.net/?f=%20x%5E3-2%5E3%3D%28x-2%29%28x%5E2%2B2x%2B2%5E2%29%20)
now, we can simplify it
