5x + 4 = 7x + 2
Subtract 5x from both sides.
4 = 2x + 2
Subtract 2 from both sides.
2 = 2x
Divide both sides by 2.
1 = x

<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
Because the square root of 49 is seven, you now have to squared values that can be used
So 1-7^2c^2
And now, because of the negative, you will have
(1-7c)(1+7c)
