Answer:
x=8
Step-by-step explanation:
set both equations equal to each other
x^2-3x-10=-2x=2
combine like terms
x^2=1x+8
x+8
Hope this helps!
Answer:
171.9 degrees.
Step-by-step explanation:
The factor is 180/π.
So 3 radians = (3*180)/π
= 171.9 degrees.
Answer:
z = 46/13
Step-by-step explanation:
Step 1: Write equation
z + 6 ÷ 13 = 4
Step 2: Solve for <em>z</em>
- Rewrite: z + 6/13 = 4
- Subtract 6/13 on both sides; z = 46/13
Step 3: Check
<em>Plug in z to verify it's a solution.</em>
46/13 + 6/13 = 4
52/13 = 4
4 = 4
Answer:
Step-by-step explanation:
Solving for x. Want to solve for f instead?
Step 1 move all terms to one side
fx - 4x² + 100 =0
Step 2 Use the Quadratic Formula
x = -f + √f² + 1600 ÷ -8, -f-√f²+1600 ÷ -8
Done.
Since the topic is similar right triangles you need to think of the Pythagorean triples, for this problem use the 3-4-5 triplet ratio
