Answer:

3.) (x + 5) (x - 6)

Step-by-step explanation:

Factor the following:

x^2 - x - 30

Hint: | Factor x^2 - x - 30 by finding two numbers whose product is -30 and whose sum is -1.

The factors of -30 that sum to -1 are 5 and -6. So, x^2 - x - 30 = (x + 5) (x - 6):

Answer: (x + 5) (x - 6)

If the point (a,3) lies on the graph of the equation 5x + y = 8 then a =?

Contact [7]

Answer:

a = 1

Step-by-step explanation:

Given the point (a, 3) is on the line: 5x + y = 8.

Any point on the line satisfies the equation.

So, (a, 3) should satisfy the equation 5x + y = 8

Substituting x = a and y = 3, we get:

5(a) + 3 = 8

$\implies 5a = 5$

⇒ a = 1

Therefore, (1, 3) is the point on the line.

63 Jelly Beans

Step-by-step explanation:

The unknown is the number of jelly beans originally in the bag or x

First he had x jelly beans

The he ate one-third of them

$\frac{1}{3}x$

He then ate 16 more jelly beans

$\frac{1}{3}x+16$

This was equal to 37 jelly beans

$\frac{1}{3}x+16=37$

This is the equation

Now solve for x

Subtract 16 from both sides

$\frac{1}{3}x=21$

Multiply both sides by 3

$x=63$

What is the approximate volume of a cylinder with a radius of 3 ft and a height of 4 ft?

Inessa [10]

The formula for the volume of a cylinder is pi x radius^2 x height, so after substituting the values, we get 3.14 x 3^2 x 4. First, we find the value of 3^2, which is 9. 3.14 x 9 equals 28.26, so now we have 28.26 x 4, which gives us 113.04. So the volume of the cylinder is 113.04. :)
