<u>Pre-Alg</u>
- Order of Operations: BPEMDAS
- Equality Properties
Step-by-step explanation:
<u>Step 1: Define inequality</u>
12 < -3(x + 4)
<u>Step 2: Solve for </u><em><u>x</u></em>
- Distribute -3: 12 < -3x - 12
- Add 12 to both sides: 24 < -3x
- Divide -3 on both sides: -8 > x
- Rewrite: x < -8
Here we see that any value <em>x</em> that is smaller than -8 would work.
I’m pretty sure it is 27.89 cm^2
Answer:
267
Step-by-step explanation:
Sum of the geometric sequence:
S n = a * ( 1- r^n ) / ( 1 - r )
a = - 4 ( the 1st term of the sequence ), r = - 6, n = 7
S 7 = (- 4 ) * ( 1 - ( - 6 )^7 ) / 1 - ( - 6 ) = ( - 4 ) * 279937 / 7 = - 159,964
