Answer:

( x + 3 )(x - 6)

Step-by-step explanation:

if you factor x2−3x−18

x2−3x−18

The middle number is -3 and the last number is -18.

Factoring means we want something like

(x+_)(x+_)

Which numbers go in the blanks?

We need two numbers that...

Add together to get -3

Multiply together to get -18

Can you think of the two numbers?

Try 3 and -6:

3+-6 = -3

3*-6 = -18

Fill in the blanks in

(x+_)(x+_)

with 3 and -6 to get...

(x+3)(x-6)

The output of a plant is 4335 pounds of ball bearings per week (five days). If each ball bearing weighs 0.0113 g, how many ball
Setler79 [48]

Answer:

The plant makes 34,802,178 ball bearings in a single day

Step-by-step explanation:

The total output of a plant in a 5-day week is 4335 pounds

Each ball bearing weighs 0.0113g

We are to calculate the number of ball bearings made per day

First, we ensure both mass are in the same unit

Now 1 pound =453.5924 grams

4335 pounds=453.5924 X 4335 =1966323.054 grams

Number of bearings made in a week therefore

= 1966323.054 /0.0113=174010889.7

≈174010890 (to the nearest whole number)

Since there are 5 days in a week of production,

Daily Production=174010890/5

=34802178

The plant makes 34,802,178 ball bearings in a single da

Answer:

The number in the middle is 60.

Step-by-step explanation:

The 2nd number = A

The 3rd number = B

The 4th number = C

Given:

(1) 130 + A + B = 300

(2) A + B + C = 200

(3) B + C + 10 = 100

Now, the work:

(2) can be modified to become A + B = 200 - C

Now, we can insert that into (1) and get the following;

130 + (200 - C) = 300

Open parentheses, simplify, you get C = 330 - 300.

C = 30

Using (3), we use above answer to get B + 30 + 10 = 100

Calculate, and get B = 100 - (30 + 10)

Simplify,

B = 60

There is your answer!

Cheers
