Combine like terms to simplify the expression. 5x + 4 + 2x + 5 will give 20 if you can answer my next question
sp2606 [1]

5x + 4 + 2x + 5

First add the like terms.

You will get this: 7x + 9

And these can't be simplified anymore because they do not both go into the same multiple.

So your answer will be:

7x + 9

Please help.

Answer:

3 2/3 square feet.

Step-by-step explanation:

You just need to multiply 6 and 4 2/3. To do this you have to change both of them into improper fractions so 6 would be 21/3 and 4 2/3 would be 14/3. If you cross cancel the 21/3 will become 7/3 and the 14/3 will become 14/1. Now you have to multiply across and you should get 98/3. To change the improper fraction into a mixed number you have to divide 98 and 3 so you can get 3 2/3. Therefore, the answer to the area of the quilt is 3 2/3 square feet.

A square acre of land is 4,840 square yards. The length of one side of the square is between which of the following?
maks197457 [2]
Hi there!

If we know the area is a square, we can use the formula for the area of a square to figure out what one side would be between. Knowing the value allows us to determine what it would be between. In this case, it is between 69 and 70.

WORK:
squareroot(4840) = 69.6

ANSWER:
Option B - 69 yd and 70 yd

The ratio of the coefficient of the quadratic term to the constant term is; a/b = 4

<h3>How to interpret quadratic equation formula?</h3>

We are told that;

1) The coefficient of the quadratic term and the coefficient of the linear term of a quadratic are equal.

2) the quadratic has a double root

Now, for the quadratic equation to be a perfect square, it must be of the form ax² + ax + b and also for this to be a perfect square, it must be (√ax+ √b)² which is ax² + b + 2(√ab)x.

Thus, we have 2√ab = a

Square both sides to get;

4ab = a²

Taking square root of both sides gives us;

a/b = 4.

Thus, the ratio of the coefficient of the quadratic term to the constant term is; a/b = 4
