- [Right Triangles Only] Pythagorean Theorem: a² + b² = c²
Step-by-step explanation:
<u>Step 1: Identify</u>
Leg <em>a</em> = <em>x</em>
Leg <em>b</em> = 5
Hypotenuse <em>c</em> = 8
<u>Step 2: Solve for </u><em><u>x</u></em>
- Substitute [PT]: x² + 5² = 8²
- Isolate <em>x</em> term: x² = 8² - 5²
- Exponents: x² = 64 - 25
- Subtract: x² = 39
- Isolate <em>x</em>: x = √39
Answer:
The cost of 4 medium pizzas:
4 (x - 3)
Step-by-step explanation:
#3
x = the cost of a large pizza
medium pizza costs $3 less than a large pizza. So it's x - 3
If 4 medium pizzas then it will be: 4 (x - 3)
Answer:
Force F = 60 ×10⁻⁵ N
Step-by-step explanation:
Given that mass of the given object (m) = 30 grams
Given that the acceleration
a = 2 m/s²
<u><em>Force:-</em></u>
The push or pull on an object with mass that causes it to change its velocity
- Force can make a body that is rest to move
- it can accelerate the speed of a moving body
<u><em>Formula for force</em></u>
The formula for force F = m a
F = 30 × 2
F = 60 gm/s²
F = 60 ×10⁻⁵ N (∵ 1 d y n = 1gm² = 10⁻⁵N

Step-by-step explanation:
second terms:
ar=3/2
forth term
ar^3=3/8
combine two equation:
r^2=1/4
r= +1/2 or -1/2
