(x + 3)^2-1=35

Create a list of steps

Answers

(X+3)^2-1=35
(X+3)^1=35
X+3=35
X=35-3
X=32

Answer:

Step-by-step explanation:

(X + 3) ( x + 3) is x^2 + 3x + 9

-1 is now 8

X^2 + 3x + 8 = 35

Subtract 8 from both sides so it now equals 27

Divide everything by 3 so its now

X^2 + x = 9 use quadratic formula and get x = -3.541 and 2.541

How many square inches are in 60 square feet?

5 square inches
72 square inches
720 square inches
8,640 square inches

Answers

Answer:

8,640

Step-by-step explanation:

One foot is 12 inches, so a square foot would be 144 inches (12×12 -> l×w) So, you would multiply 60 by 144, and you would get 8,640 square inches.

NEED HELP THIS IS MY LAST QUESTION (WRONG ANSWERS GET BLOCKED)

Answers

The greatest number of bags she can make without having any stickers or pencils left over is 18 bags.

Step-by-step explanation:

The best way to go about this is by dividing the total number of pencils and stickers by the answer choices given and starting with the highest number (27). We already know that 27 goes into 54 twice without anything left over, but can only go into 36 once while having 9 leftover. This would eliminate 27 as an answer choice as it does not meet the criteria.

Repeat the same process with 18, so 54 divided by 18 is 3, and 36 divided by 18 is 2. There is nothing left over, every bag will have an equal number of pencils and stickers. With this answer, the question criteria is true, making this the correct answer choice.

x+y=14
2x+3y=30
How do I determine which method is used for this and what is it? (Thorough explanation please)

Answers

Answer:

x = -18

y = 4

Step-by-step explanation:

x + y = 4

2x + 3y = 30

You can do any math operation to each side of the equal sign as long as you do the same operation to both sides.

change x + y = 4       to        x = 4 - y  

Now substitute (4 - y) into the second equation, in place of x.

2(4-y) + 3y = 30

multiply the 2(4-y) part:

8 -2y + 3y = 30

simplify:

8 + y = 30

subtract 8 from each side:

y = 22

now substitute the value of y back into the first equation to solve for x:

x + 22 = 4

subtract 22 from both sides:

x = -18

Check:

x + y = 4

22 -18 = 4  

4 = 4       (this checks)

2(-18) + 3(22) = 30

-36 + 66 = 30

30 =30     (this checks also)

PS: you could have solved for y first if you had wanted to. The results would be the same.

The midpoint between two points is the average of the coordinates.

mp=((x2+x1)/2, (y2+y1)/2)

In this case we are given one end point and the midpoint.

Just look at the x coordinate first.

If the mid x is 8 and the x from j is 10 we have

(10+x)/2=8

10+x=16

x=6, now for the y for j when y=6 and mid y of 5

(6+y)/2=5

6+y=10

y=4

So the coordinates of K are (6,4)
