replace the values for the letters than follow order of operations:
8(5) - 4/3 + 6 =
40-1 1/3 +6
38.67+6 = 44 2/3
Answer:
1.
is a perfect square trinomial
Step-by-step explanation:
2. Perfect square trinomials are algebraic expressions with three terms that are created by multiplying a binomial to itself.

Answer:
18x-25
Step-by-step explanation:
6x-10+12y-15
So to help with the first one
2 / x = 5
multiply the x on both sides
2 = 5x
divide by 5 to isolate the x
2/5 = x
For the second one
We will use the diamond to help us find the common factor
\ 1 /
\ /
\ /
2 / \ 4
/ 3 \
/ \
1) the product
2) and 4) the two numbers
and 3) is sum
10 is the product and -7 is the sum
so what two numbers (factors of 10)
will equal -7 when added
so we have these numbers that will equal the product of +10 and we will need to find the ones that will equal -7 as the sum
10*1, 2*5, -1*-10, -2*-5
if we add the two numbers we will find respectively
11, 7, -11, -7
As you can see that -2 + -5 = +10 and -2+-5= +10
So we have found the two numbers
now before we factor the expression looks like
( x + a) (x + b)
and when factored looks like
x^2 + (a+b)x + (a*b)
Now we can plug in the numbers and solve to see if -2 and -5 are right
(x + -2) (x + -5)
we will factor it
x^2 +-5x + -2x + 10
x^2 + -7x + 10
so a = -2 and b = -5
Hope this helps :)
Answer:
Step-by-step explanation:
Given that events are as follows:
A: A green ball is drawn from a box with five balls and placed next to the box. B: A red ball is drawn next and placed next to the green one
i.e. drawings of balls are made without replacement
Suppose there are m green balls and n red balls, where m+n =5
Prob of drawing green ball =m/5
After I draw made remaining are n red balls and m-1 green balls
Prob of drawing red ball now =n/4
Prob for drawing one green and one red simultaneously = 
Product of the two probabilities =
