Answer:
Step-by-step explanation:
3x2−2x−5=0
Let us factorize using the split the middle term method.
On inspection we observe that middle term can be split in two parts whose product is equal to the product of first and third term.
Two terms are −5xand3x
The equation becomes
3x2+3x−5x−5=0, pairing the two and taking out common factors
⇒(3x2+3x)−(5x+5)=0,
don't forget to change the sign of −5 once placed inside the parenthesis.
⇒3x(x+1)−5(x+1)=0
⇒(x+1)(3x−5)=0
Either (x+1)=0 or (3x−5)=0
We obtain x=−1,53
or x=−1,123
Answer:
Step-by-step explanation:
First let us find the area of the whole pizza. Area of a circle is:
Then, we have diameter as:
So, then using these formulas we would have,
Now, one slice is 
of the entire pizza. So, we would have:
<h2><u><em>
HOPE THIS HELPS!!!!!!!!</em></u></h2>
To do this set each of the factors to 0:
2x - 1 = 0
2x = 1
x = 1/2
x - 5 = 0
x = 5
Hope this helps!
Answer:
7 1/3 inches
Step-by-step explanation:
2 (1 3/4 + 1 11/12)
9+11
3/4+11/12= -------------
12
20/12
=1 2/3+ 2
2(3 2/3)
= 7 1/3
