Answer:
Solution given:
-2x²+7x-6=0
2x²-7x+6=0
Comparing above equation with ax²+bx+c
we get
a=2
b=-7
c=6
By using Vieta's theorem
X1+X2=
=
again
X1X2=
=
=3
The answer is 20 because 4x2 is your 8 oz so 10x2 will give you 20oz
Answer:
1. Exponents- e.is the number of times the BASE NUMBER is multiplied by itself.
2. Term- a.is a number by itself or the product of a number and variable (or more than one variable).
3. Variables- d.letters or symbols used in place of a quantity we do not know yet.
4. Coefficient- c.the number in front of a variable
5. Constant- b.is a number that stays fixed in an expression
Step-by-step explanation:
Nice and simple. PEMDAS. Parentheses, exponents, multiple, division, addiction, subtraction.
The first thing you do is solve the numbers in the parenthesis, which would turn to
(312) + (714) = 1026
This problem can be solved via a simple ratio and proportion approach. The concept is, the ratio of the actual length to the model length is constant. The solution is as follows:
Actual/Model = 12 m/ 1 cm = x/7.25 cm
Solve for x,
x = 87 m
<em>So, the actual distance is 87 m.</em>
