Answer:

The perimeter of a triangle is the measure of side 1 + measure of side 2 + measure of side 3.  To find the perimeter of the triangle, simply add these sides together.

(9x - 7w) + (4x + 6y) + (5y + 5w)

Remove the parenthesis

9x - 7w + 4x + 6y + 5y + 5w

Arrange the order so that like terms are together

9x + 4x +6y + 5y -7w + 5w

Combine like terms

13x + 11y - 2w

The average time taken to complete a test follows normal probability distribution with a mean of 70 minutes and a standard devia
Dimas [21]
Under 45 mins is roughly 16%. This is because 68% of the curve exists within 1 SD of the mean. So 16% must be outside and smaller and 16% outside and larger (on average). 

It is impossible to determine how likely you are to find someone with exactly the second amount. However, if you are looking for that or less, you would get 84%

Consider the polynomial function g(x)=x³-3x²+6x+8. Divide g by x+1.
irina [24]

Answer:

Quotient ( x² -4x +10)

Reminder -2

Step-by-step explanation:

We have to consider the polynomial function g(x) = x³ - 3x² + 6x + 8

Now, we have to divide g(x) by (x+1)

Let us arrange the terms of g(x) to get (x+1) as common.

x³ - 3x² + 6x + 8

= x³ +x² -4x² -4x +10x +10 -2

= x² (x +1) -4x (x +1) +10 (x +1) -2

= (x +1)( x² -4x +10) -2

Hence, if we divide g(x) by (x +1) then the quotient will be ( x² -4x +10) and the reminder will be -2. (Answer)
