Answer: Part A is 2 and 6 Part B is 2

Step-by-step explanation:

Part A: Here is the explanation. So, you started at with the expression 3x^2+8x+4 and when you're are factoring, you have 3x^2+px+pq+4. You can substitute the p and q for 6 and 2. What they did is they replaced 8x with px+qx. To get 8x, p needs to be 6 and q needs to be 2, or the other way around. TIP: The numbers just have to add up to 8 on this one. It doesn't have to be 6 and 2.

Part B: Here is what I got so far... 3x(x+r) is 3x^2+3xr. Also, s(x+r) is sx+sr. The equation becomes, 3x^2+3xr+sx+sr. R can be 2 and s can be 2. Here is my reasoning: The original expression was 3x^2+8x+4. We already have the 3x^2, so now we need to find what the others are by determining what r and s equal. R and s can both be 2 to make four. 2x2 is 4. Let's see if it can make 8.  3xr becomes 6x and sx becomes 2x. 6x+2x is 8x.

Among all pairs of numbers with a sum of 215, find the pair whose product is maximum. Write your answers as fractions reduced to
valentina_108 [34]

Answer:

Step-by-step explanation:

This is calculus, but I don't get fractions in the end. To maximize or minimize any function, you need to find the derivative of it, set it equal to 0, then solve for the critical values.

Our given equation is

x + y = 215 and we want to maximize the product, xy. Therefore,

y = 215 - x so its product in terms of x is

x(215-x) which is

215x -x^2.  The derivative of this is

215 - 2x. Set it equal to 0 to maximize it.

215 - 2x = 0 so

-2x = -215 and

x = 107.5.

Sub this in to solve for y:

y + 107.5 = 215 and

y = 107.5

The product is 11556.25, not that you need it.

Mr. K, his wife (Mrs. K), and their daughter (Jocelyn) went to Zionsville this past weekend for Jocelyn's first dance competitio
Nitella [24]

Answer:

Mr K purchased 6 chicken sandwiches and 6 pizza slices.

Step-by-step explanation:

Let Mr. K purchased number of chicken sandwiches = x

and number of pizza slices = y

Since total number of dancers = 12

then the equation will be

x + y = 12 --------(1)

Mr K. spent total amount = $72

Therefore, equation to purchase x sandwiches, y pizza slices and 12 drinks will be

6x + 3y + 1.5×(12) = 72

6x + 3y + 18 = 72

6x + 3y = 54

2x + y = 18 -------(2)

We subtract equation (1) from (2)

(2x + y) - (x + y) = 18 - 12

x = 6

from equation (1)

6 + y = 12

y = 6

Therefore, Mr K purchase 6 chicken sandwiches, 6 pizza slices.

Solve:<br> -4 + x = 6<br> A)-24<br> B)-10<br> C)-2<br> D)10
Nadusha1986 [10]

Answer:

x = 10 so D

Step-by-step explanation:

-4 + x = 6

add 4 both sides to get the x by itself

so 4 + 6 = 10

then the final answer is  x = 10
