The value of b^2-4ac is known as the discriminant of a quadratic function, and can tell you how many roots exist of this function depending on what it is equal to.
Start by moving the -1 to the other side, as we need this function to equal zero.
2x^2 + 3x + 1 = 0
This is now the standard form ax^2 + bx + c = 0. Plug each value that corresponds into the discriminant equation.
b^2-4ac
(3)^2 - 4(2)(1)
9 - 8
1
The value of the discriminant is 1, meaning that two real roots exist for the function described.
Irrational numbers are the subset of real numbers that are not at all connected to the rest of numbers.
The subsets of real numbers are natural numbers, whole numbers, integers, rational numbers and irrational numbers.
Natural numbers are subset of whole numbers, which are subset of integers, which are subset of rational numbers. Hence, all of them are interconnected. The set of irrational numbers is the only subset of real numbers which is not associated with the rest.
For example:-
1 is a natural number, whole number, integer, rational number but not irrational number. On the other hand, 
is an irrational number but none of the rest.

Answer:
the tree will be 11.04 feet tall
Step-by-step explanation:
4 x 0.22 (22%) = 0.88
every year it grows 0.88 foot.
0.88 x 8 = 7.04
4 + 7.04 = 11.04 feet tall
sorry if this is wrong!
Answer:
Write out your decimal as the numerator of a fraction:
0.50
/1
Multiply to remove the 2 decimal places:
0.50
/1 × 100
/100= 50
/100
Find the Greatest Common Factor of 50 and 100:
GCF is 50
Divide both numerator and denominator by 50:
50 ÷ 50
100 ÷ 50
= 1
/2
therefore your answer is 1/2
Hope this helps! （づ￣3￣）づ╭❤～
Answer:
21
Step-by-step explanation:
Add 34 to both sides.
14x = 11x + 63
Subtract 11x from both sides
3x = 63
Divide both sides by 3
21
