Answer:
AC=9 cm
ABC is not a right angled triangle
Step-by-step explanation:
AB=8cm
BC=5cm
22=AB+BC+AC
AC=22-8-5
AC=9
since AC is the longest,
using Pythagoras theorem
AC^2=BC^2+AB^2
9^2=8^2+5^2
81=64+25
81=89
therefore, it is not a right angled triangle

The expression equivalent to
Hope it helps :)
Answer:
area=432
Step-by-step explanation:
use the Pythagoras theory now that you know the width and you'll get the length and the width then you multiply both of them hope it helps you.
Answer:
x = 6
Step-by-step explanation:
-5(-2) + [8(-2)/4] = 10+(-16/4) = 10-4 = 6

<u>Newton's Law of Motions</u>
- Newton's 1st Law of Motion: An object at rest remains at rest and an object in motion stays in motion
- Newton's 2nd Law of Motion: F = ma (Force is equal to [constant] mass times acceleration)
- Newton's 3rd Law of Motion: For every action, there is an equal and opposite reaction<u>

<h3>
Step-by-step explanation:</h3>
<u>Step 1: Define</u>
[Given] F = 20.0 N
[Given] a = 5.0 m/s²
[Solve] Mass <em>m</em>
<em />
<u>Step 2: Solve for </u><em><u>m</u></em>
- Substitute in variables [Newton's 2nd Law of Motion]: 20.0 N = m(5.0 m/s²)
- [Division Property of Equality] Divide 5.0 on both sides: 4.00 kg = m
- Rewrite: m = 4.00 kg
