Answer:

x=-1

x=-2

Step-by-step explanation:

1. To solve this problem you can graph the quadratic function, as you can see in the graph attached.

2. You can estimate the solution of the quadratic function by observing two points where the parabola intersect the x-axis.

3. Keeping the the information above on mind, you can estimate that the solution is:

x=-1

x=-2

NOTE:

You can also find two numbers whose sum is 3 and whose product is 2. Then:

(x+2)(x+1)=0\\x=-2\\x=-1

Can someone please fill in blank ASAP
Annette [7]

Answer:

The quotient is 48.

Step-by-step explanation:

Estimate the quotient using compatible numbers:

45 (or I guess any number close the answer above, not sure tbh)

Multiply the estimate by 21:

945

45*21

Is the estimate to high or too low?

too low

Adjust and continue until the product is 1008.

1008/21=48

Have a good day/evening! I hope my answer is correct!

Three sevenths of a children's choir are boys. If there are 12 boys in the choir, how many children, c, total are in the choir?
ruslelena [56]

Answer:

Here c represents the total number of children  in choir.

As per the statement:

Total number of boys in choir = 12

It is also given that: Three sevenths of a children's choir are boys.

⇒ Total number of boys = \frac{3}{7} c

or

12 = \frac{3}{7}c

By cross multiply we have;

84 = 3c

Divide both sides by 3 we have;

c = 28

Therefore, the total number of children in choir is 28 children
