Answer:
+12
Step-by-step explanation:
1. distribute the negative 5 to 2y and negative 7
2. combine like term's -3+12-10y+35
3.Get the Y value by itself -44 from both sides -44-2y=
-44 -44
4. divide negative 2 from both sides<u> 2y</u>=<u>-44</u>
-2= -2
The answer is 9.2933587e+34
Base x height divided by 2
10x8=80
80÷2=40
area=40
Explanation:
First, add by 25 both sides of an equation.

Then, simplify by equation and add/subtract by the numbers.

*The answer must be have a negative sign.

Hope this helps!
Thank you!
Have a great day!

<u>Trigonometry</u>
- [Right Triangles Only] SOHCAHTOA
- [Right Triangles Only] tanθ = opposite over adjacent
Step-by-step explanation:
<u>Step 1: Identify Variables</u>
Angle θ = <em>x</em>°
Opposite Leg = 10
Hypotenuse = 21
<u>Step 2: Solve for </u><em><u>x</u></em>
- Substitute [tangent]: tanx° = 10/21
- Inverse trig: x° = tan⁻¹(10/21)
- Evaluate: x = 25.4633°
- Round: x ≈ 25.5°
