Answer:
D. x = √17
General Formulas and Concepts:
<u>Pre-Algebra</u>
- Order of Operations: BPEMDAS
<u>Trigonometry</u>
- Pythagorean Theorem: a² + b² = c²
Step-by-step explanation:
<u>Step 1: Define</u>
leg <em>a</em> = 4
leg <em>b</em> = 1
hypotenuse <em>c</em> = <em>x</em>
<em />
<u>Step 2: Solve for </u><em><u>x</u></em>
- Substitute: 4² + 1² = x²
- Exponents: 16 + 1 = x²
- Add: 17 = x²
- Isolate <em>x</em>: √17 = x
- Rewrite: x = √17
The formula for finding the axis of symmetry is x = -b/2a
So we get 2/-2
x = -1
Answer:
9 yrs ago
Step-by-step explanation:
(50-x)(20-x) = 451
x^2-70x + 1000 = 451
x^2-70x + 549 = 0
(x-9)(x-61) = 0
x = 9 (if it was 61 yrs ago, the father and son both wouldnt be a live)
