You put parenthesis around (8-(4+1)) for it to equal 3. So your final equations is 4*(8-(4+1))=12
Answer:
<h2>2.40mm</h2>
Step-by-step explanation:
In this problem. we are required to solve for the diameter of a circle.
Given data
circumference of circle c= 7.54mm
we know that the expression for the circumference is given as
c= 2πr
We can substitute our given data to solve for r
7.54= 2*3.142*r
7.54=6.284*r
divide both sides by 6.284 we have
r= 7.54/6.284
r= 1.199
diameter = 2*r
diameter= 1.199*2
diameter= 2.399
to the nearest tenth
diameter= 2.40mm
Given:
Required:
We need to find the solution by Vièta's theorem.
Explanation:
Compare 1st equation with
we get
Vièta's theorem is
now solve this equation and we get
because addition of 1 and 2 is 3 and multiplication is 2
Now for 2nd equation
apply Vièta's theorem
by this
because addition of 3 and -5 is -2 and multiplication is -15
