-12(-3)+7 please help me

-12(-3)=36

36+7 =43

hope it helps

36+7 =43

hope it helps

-12(-3)+7= 43. The parentheses makes it into multiplication, and the two negatives create a positive. -12x-3= 36. Then you add the 7 next, which makes it 43.

If n(A-B)=18,n(AuB)=70 and n(AnB)=25 then find n(B)

n(A-B) denotes elements which are in A but not in B

n(Au B) denotes elements in A and B

n(AnB) denotes elements that are common in A and B

Now I will add one more set

n(B-A) which denotes elements in B but not in A

So, n(AuB) = n(A-B) + n( B-A) +n(AnB)

70 = 18 +n(B-A) + 25

70 = 43 + n(B-A)

n(B-A) = 70-43

n(B-A) = 27

So, n(B) = n( B-A) + n( AnB)

= 27+25

= 52

A manufacturer of a certain brand of appliance estimates that he can sell 5000 units a year at Php 900.00 each and that he can sell 1500 units more per year for each Php 100.00 decrease in price? What price per unit will give the greatest returns?

First solve the return in each price per unit

Return = number units sold x price per unit

Return1 = 5000 units x Php 900

Return1 = php 4,500,000

Next is solve the other price per unit

Return2 = number units sold x price per unit

Return2 = (5000 + 1500 units0 x ( php 900 – 100)

Return2 = php 5,200,000

So the php 800 per unit will have greater return

Answer: Php 800 per unit will given the greatest returns.

Step-by-step explanation:

Since we have given that

Number of units = 5000

Cost of each unit = Php 900.00

Total cost would be

If it increased by 1500 units.

So, the number of units = 5000+1500=6500

cost is decreased by Php 100.00

So, cost becomes 900-100=Php 800

So, total cost would be

So, Php 800 per unit will given the greatest returns.

What are mathematical operations?Calculate the answer using a math operator is referred to as a mathematical operation.

Basic mathematical operations are addition, multiplication, subtraction and division.

The given numbers are 1 and 2/3,

To find 1 minus 2/3

Take difference of 1 and 2/3 by using mathematical operations,

1 - 2 / 3

= (3 - 2) / 3

= 1 / 3

The required difference is 1/3.

Add the following polynomials, then place the answer in the proper location on the grid. Write the answer in descending powers of x. Find the sum of 4x3 + 2x2 - 4x + 3 and 7x3 -4x2 + 7x + 8.

Answer:

11x^3 - 2x^2 + 3x + 11

Step-by-step explanation:

we need to find the sum of 4x^3 + 2x^2 - 4x + 3 and 7x^3 -4x^2 + 7x + 8

To find the sum we add both the polynomials

4x^3 + 2x^2 - 4x + 3 + 7x^3 -4x^2 + 7x + 8

To add the polynomials we combine like terms

4x^3 + 7x^3 = 11x^3

2x^2 - 4x^2 = -2x^2

-4x+7x= 3x

3+8 = 11

So final expression is 11x^3 -2x^2 +3x+11

4x^3 + 2x^2 - 4x + 3 + 7x^3 - 4x^2 + 7x + 8 =

11x^3 - 2x^2 + 3x + 11

11x^3 - 2x^2 + 3x + 11
