Answers:
A. -12 (6x-5)
C. 6(-12x+10)
Check out the answer A
-12(6x-5)=-12(6x)-12(-5)=-72x+60
Check out the answer C
6(-12x+10)=6(-12x)+6(10)=-72x+60

Answer: 20/3
Solution:
-5^2/-15 + 5
Determine the sign
5^2/15 + 5
Calculate
25/15 + 5
Simplify
5/3 + 5
Transform the expression
5 + 15/3
Calculate
= 20/3
(But there’s alternative forms too!: 6.6, 6 2/3)
-6 and -8.
Set as x and x-2
Create an equation of 3(x) = (x-2)-10
Solve, x = -6.
So, x-2 = -8.

<u>Trigonometry</u>
- [Right Triangles Only] SOHCAHTOA
- [Right Triangles Only] tanθ = opposite over adjacent
Step-by-step explanation:
<u>Step 1: Identify</u>
Angle θ = 35°
Opposite Leg BC = <em>x</em>
Adjacent Leg AC = 2
<u>Step 2: Solve for </u><em><u>x</u></em>
- Substitute [Tangent]: tan35° = x/2
- Isolate <em>x</em>: 2tan35° = x
- Rewrite: x = 2tan35°
- Evaluate: x = 1.40042
- Round: x ≈ 1.40
