Answer:

The answer is: 3 feet.

Step-by-step explanation:

The area is found by multiplying the width times the length. For a square, the length = the width.

Multiply 3 * 3 to get 9. So each side is 3 feet.

Solve for all values of x by factoring.<br> x^2 + 4x – 30 = -3x
vichka [17]

Answer:

{x}^{2}  + 4x - 30 =  - 3x \\{x}^{2}  + 7x - 30 = 0 \\  {x}^{2}  - 3x + 10x - 30 = 0 \\ x(x - 3) + 10(x - 3) = 0 \\ (x - 3)(x + 10) = 0 \\  \boxed{x = 3} \\  \boxed{x =  - 10}

<h3><em><u>x=3 or x=-10</u></em> is the right answer.</h3>

Answer:

700,000

Step-by-step explanation:

To explain this, we need to know the basics.

If you look at the number 790,390, you should automatically know that you can also write the same number as:

700,000 + 90,000 + 300 + 90

How did we do this?

Because each number in 790,390 has a <u>value.</u>

In fact, we can do this for any number! Like this:

12,345

You can also write the same number like this:

10,000 + 2,000 + 300 + 40 + 5

Back to the original question. If there is a seven in the hundred thousands place, that means that the 9 is equal to 700,000

Examples:

12,345

The 3 in this number stands for 300, since it is in the hundreds place.

678,900

The 7 in this number stands for 70,000 because it is in the ten thousands place

Now you know!

9. Order the angles of the triangle from smallest to largest
12345 [234]

Answer:

It is b. ACB

Step-by-step explanation:

If draw a triangle, you would give the longest side to BC, because their angles equal 10

And you would give AC the shortest side of the triagle because their angles equal 7

And AB the last side because it is in between the other sides

Since AC have the smallest angle, they would have the smaller numbers

then that leaves B as the biggist number
