PLEASE QUICKLY HELP ME!!

Mathematics
1 answer:
Ksju [112]3 years ago
3 0

Answer:

Part A: 16x^2 -56x+49

I'm not quite sure on Part B and C though, sorry :/.

Step-by-step explanation:

To find the expression we need to solve (4x-7)•(4x-7)

4x•4x = 16x^2

4x•-7= -28x

-7•4x= -28x

-7•-7=49

Combine alike terms

16x^2-56x+49

Hope this helps! If you have any questions on how I got my answer feel free to ask. Stay safe!

according to the 2000 U.S. Census, 138,053,563 Americans are male, and 143,368,343 Americans are female. About what percent of f
Novosadov [1.4K]

Givens

Male  =      138,053,563

Female =   143,368,343

Total

The total equals 281 421 906

Percents

Male = (138,053,563 / 281 421 906) * 100 = 49.1%

Female = ( 143,368,343/ 281 421 906) * 100 =  50.94%

Rounded

Male =  49

Female = 51

Comment.

To find this %s you could just use the first 3 digits of everything.

Total = 138 + 143 = 281

% male = (138/281) = 49.1

% female = (143/281) * 100 = 50.88

These give you the same answers when rounding.

Two integers A and B have product of 24 what is the least possible sum of A and B
jeka94

The answer would be -25.


Before we get to the solution, we need to remind ourselves that integers are whole numbers, but they include even negative numbers.


First we need to look at least two factors of 24.

Positive:

24 x 1 = 24

12 x 2 = 24

8 x 3 = 24

6 x 4 = 24

Negative:

-24 x -1 = 24

- 12 x -2 = 24

-8 x - 3 = 24

-6 x -4 = 24


Now lets add these factors and see the sum of each of these factors:

24 + 1 =25

12 + 2 = 14

8 + 3 = 11

6 + 4 = 10


-24 + -1 = -25

- 12 + -2 = -14

-8 + - 3 = -11

-6 + -4 = -10
