Answer:
x=3.4
Step-by-step explanation:
I could be wrong but I'm pretty sure this is the answer.
Answer:
It is 121
Step-by-step explanation:
The solutions are:
x = −4,x = 7
Explanation:
X^2−3x−28= 0
We can first factorise this expression by splitting the middle term and then find the solutions:
= x^2−7x+4x−28=0
= x( x−7) + 4( x − 7)=0
=(x+4)(x−7)
Now, we can equate the two factors with zero and find the solutions:
x+4=0,x =−4x−7=0,x=7
1. The natural numbers are those that are used for counting. Natural numbers cannot be negative.
2. A whole number is a member of the set {0,1, 2, 3, …} - this set is the set of natural numbers with zero. Whole numbers cannot be negative.
3. Integers include whole numbers and negative whole numbers. Integers can be positive, negative, or zero.
4. Real numbers include:
- natural numbers;
- whole numbers;
- integers;
- rational numbers;
- irrational numbers.
Real Numbers can also be positive, negative or zero.
Consider number -1.2. It is negative, then options 1 and 2 are wrong. Also option 3 is false, because 1.2 is not natural number (cannot be used for counting), then -1.2 is not integer. Number -1.2 is real number.
Answer: correct choice is D.
Answer:
We need to find its Hypotenuse
H² = 14² + 48²
H² = 196 + 2304
H² = 2500
H = √2500
H = 50
