Perform the operation. (-x^2 – 1) – (-2x^2 – 4)

Mathematics
1 answer:
ivolga24 [154]3 years ago
6 0

Answer:

Okay!

Step-by-step explanation:

I have simplified the operation, and I got x^2 + 3.

If you wanted me to evaluate, the answer is still  x^2 + 3.

If you wanted me to subtract then the answer is again,  x^2 + 3.

Basically the answer is  x^2 + 3.

Have a good day!

A salesperson earns a commission based on the number and type of vehicle sold. A person selling 6 cars and 3 trucks earns $4,800
madam [21]
4800 divide by 3=1600 (2 cars 1 truck)

4600-1600-3000 (6 cars)

3000 divide by 3 = 1000(2cars)

1000 times 2=2000(4 cars )

4800-2000-2800 (2 cars 3 trucks)

<h2><u>PLEASE MARK BRAINLIEST!</u></h2>

Answer:

To find the scale factor, all you have to do is <em>divide a side value of one figure by its congruent side value on another figure. </em>

Step-by-step explanation:

To start:

  • The values 15 and 10 are both for the same congreunt side --> EF and E'F'
  • The values 4 and 6 are both for the same congreunt side --> DE and D'E'
  • The values 4 and 6 are both for the same congreunt side --> DG and D'G'
  • The values 8 and 12 are both for the same congreunt side --> FG and F'G'

So, to find the scale factor, all you have to do is divide the smaller congruent value from the larger congruent value.

Larger congruent value ÷ smaller congruent value = scale factor

              15                      ÷                10                        = scale factor

              \____________________/

                                    1.5

<h3>So, the scale factor is 1.5</h3>

To double check, we will use another congruent side to find the scale factor:

12 ÷ 8 = scale factor

1.5      = scale factor

<h3>So, the scale factor is most definitely 1.5</h3>

I hope this helps!
