Answer:
if you are solving for X
Step-by-step explanation:
first you do a thing i call jump multiplying
so like 5x2X+ 5x4
then you do basic maths
10X=20
X=2
Answer:
X1=(-3+7)÷2=2---> X1=2-->First root
X2=(-3-7)÷2=-5---> X2= -5-->Second root
Step-by-step explanation:
X^2=-3X+10 you need to change the order of this equation
X^2+3X-10=0---> You do this in order to do BHASKARA
then you do BHASKARA
-3(±√9-4·1·-10)÷2·1
X1=(-3+7)÷2=2---> X1=2-->First root
X2=(-3-7)÷2=-5---> X2= -5-->Second root
Answer:
6 and 8
Step-by-step explanation:
The hypotenuse of a 30°-60°-90° triangle measures 10 inches.
To find the length of one of the legs, we use the idea of Pythagorean Triples.
Pythagorean Triples are any set of three numbers that satisfies the Pythagorean Theorem. Some common examples are:
- 3, 4 and 5
- 5, 12 and 13
- 9, 40 and 41
Note that in a Pythagorean Triple,
- The longest length is always the Hypotenuse.
- New Triples can be formed from product of existing triples.
In our given triangle, the Hypotenuse=10 Inches
Consider the Pythagorean Triple 3,4, and 5
- 5 is the Hypotenuse
- Multiply the Triples by 2, we obtain:
- 6, 8 and 10 (in which 10 is the hypotenuse)
Therefore, 6 and 8 could be the length of a leg of the 30°-60°-90° triangle.
Answer:Deductive approach
Step-by-step explanation:
The deductive approach is described as reasoning from particular to general hence,
-Hypothesis is derived from theory
-Hypothesis is tested or observed
-Conclusion is made based on test
Deduction is a direct opposite of induction whereby observation is made first to derive a pattern to make hypothesis and then conclude on a theory.
Answer:
12/5 - 2p
Step-by-step explanation:
Use the distributive property:
2/5 * 6 - 2/5 * 5p = 12 / 5 - 2p
