Determine the value of c that will result in a perfect square trinomial.
w^2+6w+ c =130+c
Answer:
The value of c that will result in a perfect square trinomial is (3)^2 or 9
The perfect square trinomial is: [tex](w+3)^2=139[/tex]
Step-by-step explanation:
We need to determine the value of c that will result in a perfect square trinomial.
[tex]w^2+6w+ c =130+c[/tex]
Perfect square trinomial are of form: [tex]a^2+2ab+b^2=(a+b)^2[/tex]
Now, the equation given is:
[tex]w^2+6w+ c =130+c[/tex]
Looking at the term 6w, we can write it as 2(w)(3)
We are given: a = w, 2ab = 2(w)(3) so, b will be: (3)^2
So, we will be adding (3)^2 on both sides
[tex]w^2+6w+ c=130+c\\w^2+2(w)(3)+ (3)^2 =130+(3)^2\\The\:left\:side\:becomes: a^2+2ab+b^2\\We\:can\:write\:it\:as: (a+b)^2\\We\:have\:a=w\: and\: b=3\\(w+3)^2=130+9\\(w+3)^2=139[/tex]
So, The value of c that will result in a perfect square trinomial is (3)^2 or 9
The perfect square trinomial is: [tex](w+3)^2=139[/tex]
The sum of two consecutive integers is −51. Find the integers.
9514 1404 393
Answer:

x and z are opposite, x= -10, where as z = 10, Hence x times (-1) equals z.
An integer is a non-fractional number real number. It can be either negative or positive, it simply cannot be a fraction.
"w", "x", and "y" are negative, and hence less than zero.

6 help neededddd!!
Answer:
-2 < x ≤ 6
Step-by-step explanation:
This graph shows conjunction. This means that the two statements of the inequality bare true at the same time. Therefore, it follows that:
x > -2 ("we use greater than" because the empty/unshaded circle indicates that -2 is not included)
And
x ≤ 6 (we use greater than or equal to because the shaded circle indicates 6 is included)
Joining both statements together, we would have:
-2 < x ≤ 6

Paul is filling a kiddy pool that can hold up to 25 gallons of water. The water hose fills the tub at a constant rate. When Paul checks the pool, it contains 5 gallons of water. Three minutes later, the pool contains 7.4 gallons of water. At what rate does the pool fill up with water?
Answer:
0.8 gallons per second
Step-by-step explanation:
Given that :
Filling occurs at a constant rate ;
Change in gallon of water in pool within a 3 seconds time interval ;
Assume :
At t = 0 ; gallons = 5
At t = 3 ; gallons = 7.4
Chanhe in gallons with time.;
(7.4 - 5) / (3 - 0)
2.4 / 3
= 0.8 gallons per second

Meg is packing a shipping conditier.
There is one section of the shipping container that has not yet been packed. The space available is in the shape of rectangular
prism that measures 2 feet by 3 feet by 33 feet.
She will pack as many boxes into the available space as possible. Each box is in the shape of a cube with side length 1 foot.
The space available in the shinning container and one of the boxes are shown below.
Answer:
[tex]Boxes= 198[/tex]
Step-by-step explanation:
This question has uncleared details towards the end. However, one can deduce that we need to calculate the amount of box the available space can contain.
We have the following given parameters.
Shipping Container
[tex]Dimension: 2ft\ by\ 3ft\ by\ 33ft[/tex]
The box
[tex]Dimension: 1ft\ by\ 1ft\ by\ 1ft[/tex]
First, we calculate the volume of the shipping container.
[tex]V_A = 2ft * 3ft * 33ft[/tex]
[tex]V_A = 198ft^3[/tex]
Next, we calculate the volume of the box.
[tex]V_B = 1ft * 1ft * 1ft[/tex]
[tex]V_B = 1ft^3[/tex]
The number of box is then calculated as:
[tex]Boxes= \frac{V_A}{V_B}[/tex]
[tex]Boxes= \frac{198ft^3}{1ft^3}[/tex]
[tex]Boxes= \frac{198}{1}[/tex]
[tex]Boxes= 198[/tex]
Hence:
198 boxes will occupy the empty space

What is the y-coordinate?
Enter your numeric answer only.
Answer:
i have find the value of x and y in above figure hope it helps
The y-coordinate that represents the solution to the system of equations is 4
The equations are given as:
[tex]-x+y=1[/tex]
[tex]3x-y=5[/tex]
Make x, the subject in the first equation
[tex]-x+y=1[/tex]
[tex]x = y - 1[/tex]
Substitute y - 1 for x in the second equation
[tex]3x-y=5[/tex]
[tex]3(y - 1) - y = 5[/tex]
Open the brackets
[tex]3y - 3- y = 5[/tex]
Collect the like terms
[tex]3y - y = 5+3[/tex]
Evaluate the like terms
[tex]2y = 8[/tex]
Solve for y
[tex]y = 4[/tex]
Hence, the y-coordinate is 4
